The Great Expansion: Proto-Mark and the Pro-Gentile Enlargement of Canonical Mark

1.1 The Criteria

Based on the proposed synoptic tree, we argue that proto-Mark can be identified by three source-critical criteria applied on purely formal grounds, without reference to theme. First, Luke shows no knowledge of Mark's specific wording in these passages. Second, Luke shows no knowledge of Mark's ordering of them. Third, the material forms a single large contiguous block — precisely what one would expect when an author is inserting into a scroll rather than recopying from scratch, since a scroll admits new material most economically at a single splice point rather than at many distributed ones.

A fourth confirming mark is that the text shows internal seams where the material was joined. The thematic character of expansion to canonical Mark is a result of applying these formal criteria: the material turns out to be uniformly pro-Gentile, in most cases not on the surface of the text but against the scriptural substructure the following sections trace.

That the pro-Gentile sense is so often concealed rather than displayed is, I will suggest, not accidental. The meaning was not meant to be read off the page but disclosed in the telling: Mark read the narrative to his hearers while expounding its hidden sense to them. That larger thesis — Mark as a reserved text disclosing Pauline soteriology in the reading — is reserved for a forthcoming study (Gentile, 2026c). The present study concerns itself with the form of proto-Mark and its expansion into canonical Mark.²

2.1 The Centerpiece of the Argument

The core of the argument is the so-called Great Omission — the block of material present in canonical Mark (6:45–8:26) but absent from Luke. The standard explanations are that Luke's copy of Mark was physically damaged at this point, or that Luke knew the material and chose to omit it. We argue for a third account: proto-Luke relied on proto-Mark, which never contained the block except for its closing pericope, the two-stage healing of the blind man at Bethsaida (8:22–26). The block is therefore not an omission at all but an expansion — material the original author added when he enlarged proto-Mark into canonical Mark.

The thematic character of the block turns out to be uniformly pro-Gentile, and that uniformity tells against both rival explanations. Luke was demonstrably not anti-Gentile, so there would be no reason for him to selectively excise just such material. Against the damaged-scroll explanation the point is sharper still. A damaged scroll can, of course, remove thematically unified material — but only if the text already held that material in a single thematically unified span. Had canonical Mark's Gentile material been distributed through the gospel, interleaved with the rest, a random loss would have carried off a thematically mixed stretch, and Luke would be missing a miscellany. The uniformity, in short, points past accident to design — confirmed below by the still stronger fact that the clustering is not merely thematic but structural, the missing material proving to be, pair by pair, the Gentile member of doublets whose Israel members Luke retains.

The expansion's design is shown most decisively by that structure. The added material does not merely share a pro-Gentile theme; it repeatedly pairs with material already standing in proto-Mark, forming Jewish/Gentile doublets in which an inherited Israel member and an added Gentile member answer to each other. The most transparent of these pairs is the feeding of the five thousand, present in Luke — proto-Markan, Israel-facing, laden with Exodus typology — alongside the feeding of the four thousand, absent from Luke, which belongs to the expansion, faces outward to the nations, and carries the typology of Isaiah's new Exodus (Watts, 1997). Material missing from Luke that turns out to be, pair by pair, the Gentile half of a set whose Israel halves Luke retains is not what accident produces; it is what composition produces. The pairs themselves are set out below; here it is enough to say that the structure they form is the signature that the block was built.

2.2 The Secondary Blocks: Beelzebul and the Fig Tree

The Great Omission is the centerpiece of the argument, but two further places meet our three criteria, each with a caveat that must be stated openly.

The first is the Beelzebul controversy (3:22–30). This is the largest of what Two-Source Hypothesis scholars call "Mark/Q overlaps" — passages where Luke appears to draw on both Mark and Q simultaneously. In reconstructions, Q collapses onto the text of Matthew: Luke shows no independent knowledge of Mark's wording, and no knowledge of Mark's placement of the controversy. The two-fold absence is clean. Adjacent to the Beelzebul controversy³ in canonical Mark stands the appointment of the Twelve (3:13–19), which forms the Gentile half of a Jewish/Gentile pair — its Jewish counterpart being the sending of the Twelve (6:7–13), which stood in proto-Mark. Together, the Beelzebul controversy and the appointment constitute a block of two successive pericopes, satisfying our size criterion for a large section.

The caveat here is twofold. On order: while Luke technically does not share Mark's placement, the two are close — both agree the material belongs shortly after the healing of the paralytic, which makes the order criterion weaker here than for the Great Omission. On wording: Luke shows one clear connection to his Markan source that cannot be explained through Matthew. In the disciple list, Luke and Mark read "Matthew, Thomas" where Matthew reads "Thomas, and Matthew the tax collector" — Luke agrees with Mark against Matthew at exactly this point, showing that his Markan source carried a form of the Twelve list. Our hypothesis therefore is not that the appointment was wholly absent from proto-Mark, but that proto-Mark already carried the choosing of the Twelve and their list — the naming of Peter included — in a form Luke's tradition received, and that the canonical expansion framed it: linking it to the Isaiah 49 commission of the Servant and to the Beelzebul controversy that follows, and making the appointment the Gentile-facing counterpart to the Jewish-facing sending of the Twelve — then inserting the reframed appointment together with the Beelzebul controversy as a new block. Luke's wording agreement is with the proto-Markan list he inherited; the expansion's framing additions are what he does not attest.

The second relatively secure candidate is the cursing of the fig tree (11:12–14, 20–25). Luke shows no knowledge of Mark's wording and no knowledge of Mark's order for this material, satisfying the first two criteria. The size criterion, however, requires a caveat of a different kind: the fig tree qualifies as a large section only if the temple cleansing (11:15–19) is counted as part of the intercalation it brackets. The cleansing itself stood in proto-Mark — Luke attests it (19:45–46), together with its aftermath. What the expansion added was the frame: the two fig-tree halves, absent from Luke in both position and wording, were wrapped around the inherited cleansing to create the characteristic Markan intercalation (Edwards, 1989), in which the withered tree and the judged temple interpret one another. The insertion was a physical act of recopying — to sandwich the cleansing between the two fig-tree halves, the expander had to transcribe it anew — and it is in that recopying, we argue below, that he made at least one light interior edit: the clause "for all the nations" at 11:17, which carries the cleansing's pro-Gentile sense. Its assignment to the expansion rests on the converging grounds set out below, source-critical among them — the clause is absent from Luke, who of all the evangelists would least have dropped "a house of prayer for all the nations." The internal seams that each of these blocks bears in the text of Mark — traces that would mark them as insertions even without Luke — are developed block by block in the sections that follow.

2.3 The Tertiary Fragments

Up to this point the expansion material has been identified by source-critical means alone. When we turn to search for smaller items that may also belong to the expansion, however, the third criterion — that the material form a large contiguous block — can no longer apply. And if we rely on the first two criteria alone, all of Sondergut Mark would technically qualify, since by definition Luke attests neither the wording nor the position of material unique to Mark. The pro-Gentile character established for the larger blocks is therefore pressed into service as an additional criterion at this stage. We look for material where Luke shows no direct connection to Mark's wording or order, and where the text is pro-Gentile — or at least plausibly so in the mouth of an author standing behind his text and expounding its hidden sense to his hearers. We also search for plausible seams in the text of Mark.

Two passages answer to this description, and we review them briefly below. But because none can be secured by the formal criteria that anchor the larger blocks, and because the additional pro-Gentile criterion is softer and more open to dispute, the safer course is to leave these smaller fragments out of the reconstruction as a whole, noting them as possibilities rather than incorporating them. The firm boundaries of the expansion are therefore the three sections fixed by the formal criteria above.

A further candidate is the night trial (14:55–64). This candidate was raised in correspondence after this study was first drafted and is treated at full length in a supplement (Gentile, 2026d). The evidence — an insertion seam with resumptive stitch (14:54 → 14:66), the emptied morning slot at 15:1, the shape of Luke's hearing (22:54–71), and a mimesis argument published by Wendling in 1908 — supports the candidate in a specific form: not outright insertion but relocation and expansion of a morning hearing proto-Mark already contained, in the slot where 15:1 still stands and where Luke still holds it. The candidate is graded below the centerpiece, for its Lukan evidence is divergence rather than absence; what carries it is that the divergence falls along the seam Mark's own text marks. Among its yields for the series: the expansion, on this candidate, converted the hearing's deflection ("you say that I am," so still Luke 22:70) into the gospel's one open messianic declaration (ἐγώ εἰμι, 14:62) — a result whose weight belongs to the third study.

One refinement to the model above emerged from the supplement's candidate and is recorded here because it belongs to the tree rather than to any one pericope. The two editions of Mark did not travel in sealed containers: they circulated in the same communities within a generation, and copies of the new edition inevitably carried sporadic wording of the old, harmonized in by copyists who knew proto-Mark by ear. Matthew's copy of Mark was such a copy — canonical in structure, occasionally proto-Markan in phrasing at the points the expander had altered. The refinement is additive, not corrective: nothing in this study's arguments assumed otherwise. Its yield, argued in the supplement, is a solution to the minor agreements of Matthew and Luke with Holtzmann's pedigree and two testable distributional predictions.

2.4 The Thematic Character of the Expansion

The thematic character of the expansion is a finding, not a premise — and it is this finding that licenses the search among the smaller fragments. The expansion proves to concern two faces of a single program: the inclusion of the Gentiles, and the supersession of the temple cult that had excluded them. Its members distribute across three groups according to how directly they display this orientation. In the first, the Gentile bearing is on the surface or nearly so: the Syrophoenician woman, the handwashing dispute over clean and unclean, the Decapolis deaf-mute, the feeding of the four thousand. In the second, it emerges only against the scriptural substructure the following sections trace: the appointment of the Twelve under the Servant's call to be "a light to the nations" (Isa 49:6). In the third, the bearing is anti-cultic and Gentile by consequence: the fig tree's "house of prayer for all the nations" framing the temple's judgment (Isa 56:7). Some members wear the theme openly; others disclose it only to a reader who follows the scripture beneath them — which is, as a forthcoming study (Gentile, 2026c) will argue, exactly the design the gospel's own esotericism would predict.

That this orientation is an output of the criterion rather than an input to it can be verified directly. The criterion excludes the Gerasene demoniac (5:1–20): Luke follows Mark's wording and order there, so it does not qualify, despite being one of the more overtly Gentile episodes in the gospel. The criterion does not simply gather up everything that looks pro-Gentile. And this exclusion carries a further implication: proto-Mark was not anti-Gentile. The Gerasene demoniac shows that Gentile-positive material stood in proto-Mark from the beginning. What the expansion did was not introduce a new orientation but intensify and systematize one already present, making it the explicit program of the enlarged gospel.

2.5 A Possible Objection

An objection must be met before these criteria can do any work — one that will already have occurred to any reader who has studied the source diagram above. If Luke used Matthew, and Matthew reproduced much of the expansion material from canonical Mark, then Luke had indirect access to that material through his Matthean source. Does this not cause a problem for the model? If Luke saw the material in Matthew and declined it, why can we not conclude that he might have declined it in his Markan source too — in which case its absence from Luke tells us nothing about whether it stood in proto-Mark?

The objection dissolves once the documentary model's own structure is kept in view, for it conflates two authors at two different layers into one. The model posits not a single Lukan writer with multiple source-routes but a proto-Luke and a later canonical Luke, and the silence is explained differently — and without competition — at each layer. The proto-Luke author could not include the expansion material: it was not in proto-Mark, his only Markan source, and one cannot transmit what one has not received. His lack is source-absence in the strict sense, and requires no motive. The canonical-Luke redactor, by contrast, could in principle have drawn the expansion material from Matthew, whom he now had in hand — and did not. His failure to restore it is not source-absence but decline, and there are two independent reasons for it.

The first reason turns on how canonical Luke used his two sources, and it is here that the objection's central assumption breaks down. The objection treats "Luke declined material in Matthew" and "Luke would have declined it in Mark" as symmetrical, but the model gives the two sources entirely different roles, and Luke reads them in entirely different ways. Proto-Luke follows his Markan source continuously — transcribing its narrative spine in order, as proto-Luke does with Mark throughout the gospel — so that a large connected block standing in that source would have been carried over as a matter of course; its absence from Luke is therefore strong evidence of its absence from the source. Canonical Luke, by contrast, does not transcribe Matthew; he mines it selectively, taking individual items that serve his purposes and leaving the great bulk of Matthew's distinctive material — special-M — untouched. His borrowings from Matthew (along with occasional coincidences) explain the minor agreements (Neirynck, 1974) and are the likely source of much of what Two-Source scholars call the Mark/Q overlaps, but they are borrowings of items, not of blocks. One would not expect such a redactor to lift a large, connected block of Markan narrative out of Matthew and splice it in; that is simply not how he treats that source. The asymmetry is the whole answer: continuous transcription of one source, selective mining of the other. Silence in a continuously-transcribed source is telling; silence in a selectively-mined one is not.

The second reason is thematic, and it turns on the character of the later Lukan redactor. That canonical Luke expanded an earlier Lukan text with Matthean material is argued in the previous study (Gentile, 2026a); that this expansion served to re-ground the gospel in its Jewish origins, against the de-Judaizing tendency Marcion would come to represent, is argued by Tyson (2006), who reads canonical Luke-Acts as a redaction shaped in that struggle. Luke's addition of the birth narratives — saturated with temple piety and Jewish expectation, and precisely the material Marcion's gospel would lack — works to the same end. His unifying aim is no less clear: canonical Luke's authorship of Acts makes its irenic, faction-reconciling theme unmistakable, and in the next study of this series (Gentile, 2026c) we argue that his soteriology, too, reads as a compromise between competing parties. His additions from Matthew were governed by this double program — to re-ground the gospel in Israel and to hold its Jewish and Gentile faces together — and what he took fits it with precision.

On the reconstruction offered here, he drew from Matthew chiefly the largest narrative pieces of the double tradition, and his selections cluster around John the Baptist and the beginning of Jesus's ministry — material adjacent to the origins his own opening chapters would re-ground in Israel — together with items serving his unifying aim, most notably the Beelzebul controversy (most plausibly for the "house divided" saying, apt to a writer preaching against faction). His two objectives — to re-ground the gospel in its Jewish origins and to hold its Jewish and Gentile faces together — are served by exactly these selections. A large block of Markan Gentile-mission narrative served neither: it re-grounded nothing in Israel, and a block of miracles among the nations served his unifying purpose no better than the material he had already taken. Available to him though it was, secondhand through Matthew, it was simply not what this program reached for — and so, like most of what he found in Matthew, he left it. Proto-Luke could not include the expansion material; canonical Luke, mining Matthew selectively and by a program the block did not serve, would not⁴.

2.6 The Relative Weight of the Criteria

In the course of writing this study, our view of the relative weight of these criteria shifted, and it is worth stating plainly which of them bear the most load. They are not of equal force. The size of a block, and the absence of Mark–Luke agreement in wording against Matthew, each must be examined in detail, but each is typically applied with caveats; thematic fit, once a block has been identified, can do real work, but it is the most subjective of the criteria. The load-bearing pillars are of a different kind: an internal seam in the text of Mark that coincides with Luke either placing the material in a non-Markan location or lacking it altogether. These leave no room for caveat. Every major block identified in this study — together with one minor one, the anointing, which may meet them — meets them and also satisfies the slightly more flexible criteria; but it is the seams, and Luke's placement, on which the strength of the case for the existence of proto-Mark rests.

3.1 The First Internal Seam: Bethsaida

The first argument generally raised in favor of omission was observed by (Streeter, 1924), and it has been a standard argument ever since. Luke, having no part of the block, nonetheless betrays knowledge of one item within it. At Luke 9:10 he locates the feeding of the five thousand at Bethsaida — "he withdrew privately to a city called Bethsaida" — but in Mark the feeding is in a deserted place (6:31–32), and Bethsaida belongs not to the feeding but to what follows: it is where the disciples are directed as the block opens (6:45) and, at its close, where the blind man is healed (8:22). Luke's Bethsaida is attached to the wrong episode. The conventional reading takes this as a fossil proving Luke knew the whole block and dropped it⁵.

The standard theory's best evidence, however, can be turned against it. The seam is real; its implication is not what the conventional reading supposes. A bleed of the name Bethsaida is evidence of contact with the Bethsaida pericope — the blind-man healing — and with nothing else in the block. It is not evidence of contact with the walking on the water, or the Syrophoenician woman, or the four thousand, none of whose locales or names surface anywhere in Luke. The economical inference is that proto-Mark carried the feeding of the five thousand and, in close proximity, the Bethsaida healing; that Luke's tradition received both; that Luke omitted the healing while retaining the feeding; and that the displaced place-name thereby lodged against the feeding. Strip the expansion away and proto-Mark reads, in effect, "…and they took up twelve baskets. He went away to pray. And they went toward Bethsaida. And they come to Bethsaida, and they bring to him a blind man…" — feeding and healing all but consecutive, exactly the adjacency a single bleeding place-name requires.

These points deserve emphasis. First, in canonical Mark Bethsaida appears at 6:45 and again at 8:22 — separated by the entire expansion block. In proto-Mark, by contrast, the departure for Bethsaida and the arrival at Bethsaida were consecutive: a coherent journey that the expansion has split apart. Second, on the standard view Luke skipped those eighty verses and the name migrated backward across that gap to attach to the feeding — a considerable displacement requiring explanation on any account. On our hypothesis no such displacement is needed. When Luke omitted the healing, the place-name found itself adjacent to the feeding and lodged there naturally. The bleed is a short step, not a long one.

This converts the opposition's strongest datum into a support for the expansion case, but it carries a debt that must be paid honestly. The Bethsaida healing becomes the one pericope within this stretch that Luke genuinely omitted — possessed and discarded — and the reader is owed a reason why this single unit was dropped while the model's general claim is that Luke's absences across the block are non-existence rather than omission. There is a principled reason, and it does not strain. The healing is a two-stage, saliva-mediated cure (Mark 8:23–25), the most physically graphic of Markan miracle techniques, and it is exactly this kind of healing the early redactors found awkward. Matthew, who plainly had the block, likewise omits this healing, and likewise generalizes away the other spittle-cure within it, the Decapolis deaf-mute (7:31–37), into a summary notice (Matt 15:29–31). Two evangelists independently declined the same saliva-based cures. Luke's omission of the Bethsaida healing is therefore not an ad hoc rescue invented to save the seam; it is an instance of an editorial reflex demonstrable elsewhere in the tradition, and wholly in character for an evangelist who makes choices at the level of the individual pericope.

3.2 Contiguity: Against Deliberate Omission

A first-century gospel was written on a papyrus roll, manufactured by gluing prepared sheets edge to edge (Gamble, 1995). To insert new material into the middle of such a roll, an author could recopy the whole onto a fresh roll — an immense labor — or cut the roll at one point and splice in additional sheets carrying the new text. The second is far cheaper, and it has a textual consequence: additions made this way cluster, because one splice admits one block, and distributing the same quantity throughout would require many cuts and many splices. Single-author expansion of a roll will therefore tend to be lumpy and contiguous rather than evenly diffused.

This consideration does real work, but its limits should be conceded plainly. It does not tell against the damaged-exemplar theory at all: a lost leaf also produces a contiguous gap, so contiguity is equally at home there. Against deliberate omission, however, it does tell, and with some force. The block comprises eight or nine distinct pericopes — separate stories, not a single repeated unit. If Luke's grounds for omitting Markan material were specific to each pericope, as his scattered omissions elsewhere in the gospel are, then his dropping eight such units and their happening to fall in an unbroken run is a coincidence of low probability: on a rough estimate, treating the omissions as independent, the odds against eight displeasing pericopes lying contiguous in Mark, with no retained island among them, run to the order of many tens of thousands to one. Note, we are not claiming that the author Luke acted randomly, but that a priori, one would expect “Luke-displeasing text” to be randomly distributed in his source text.

The omitter has one escape, and only one. He may deny that the omissions are independent — recasting the block not as eight decisions but as a single one, a unified stretch Luke rejected as a block for some feature common to the whole (a perceived "duplicate cycle" of sea-crossing, feeding, and dispute, say). If the block is one displeasing thing, its contiguity is no coincidence and the probability argument lapses, for one cannot compute the odds of eight independent events coinciding where there were never eight independent events.

But this escape is barred by the content of the block itself, and it is the content that decides the matter. The recasting works only if the block is uniformly the kind of material Luke would wish to drop, and it is not. The Syrophoenician woman (7:24–30) is a Gentile-faith vignette of exactly the sort Luke elsewhere prizes — compare his amplification of the centurion's faith ("not even in Israel have I found such faith," 7:9) and his programmatic appeal to the widow of Zarephath and Naaman the Syrian (4:25–27); the Decapolis deaf-mute healing (7:31–37) ends in an acclamation Luke would have had no reason to spurn. A block containing material Luke wanted cannot be the unified, wholesale-displeasing block the escape requires — which throws the omitter back upon independent, pericope-by-pericope decisions, and it is independent decisions that the improbability of contiguity tells against. The argument is therefore not a probabilistic knockdown pressed in the abstract; it is the conjunction of two observations — that the omissions, if deliberate, must be independent, and that their falling contiguous is improbable if they are. Neither alone suffices; together they make deliberate omission an uncomfortable account of the block.

The typical rejoinder conflates individual decisions with a block decision: "Luke saw enough to dislike that he junked the whole thing." But this is precisely the conflation the conjunction defeats. If Luke saw "enough to dislike," then within the block there must be material he would have welcomed — the Syrophoenician woman being the clearest case — and a competent editor does not junk material he welcomes to be rid of material he dislikes, when omitting only the latter would cost him nothing. The "block decision" presupposes a uniformity of distaste the block does not have. Either Luke chose unit by unit (and the contiguity becomes improbable) or he discarded a block (and the welcome-able material inside it becomes inexplicable).

3.3 The Argument from Distribution: Against the Damaged Exemplar

Against the damaged-scroll theory the decisive consideration is distribution. If Luke lacks the block because his exemplar of Mark was physically defective, the defect must be confined to Luke's copy alone — for canonical Mark has descended to us with the block intact, and Matthew plainly had it, reproducing its walking on the water, its dispute over defilement, its Canaanite (Syrophoenician) woman, and its feeding of the four thousand (Matt 14:22–16:12). The damage would thus have to fall on a single late branch while leaving the archetype that reached Matthew, and the entire surviving manuscript record, untouched — a special and unattested accident, localized exactly where the theory needs it and invisible everywhere else.

The expansion hypothesis requires no accident at all. Luke's line descends from proto-Mark, which never contained the block; Matthew's descends from canonical Mark, which did; and the manuscript tradition transmits canonical Mark. The observed distribution — Matthew has it, we have it, Luke lacks it — falls directly out of the document tree, with no appeal to physical damage anywhere. The damaged-exemplar theory must posit a defect both perfectly placed and perfectly invisible; the expansion theory derives the same facts from the relationships among the documents themselves.

It has occasionally been suggested that the abrupt ending at Mark 16:8 reflects similar physical damage to the gospel's autograph. Whatever the merits of that proposal in its own context, it cannot be enlisted in support of the omission view here, and indeed creates a difficulty for it. The supposed damage at 16:8 is what the entire surviving tradition transmits — every manuscript ends at that point — whereas the supposed damage at 6:45–8:26 is not what the tradition transmits, since canonical Mark and Matthew alike preserve the block. The two cases distribute oppositely, and to make them both physical damage requires positing two independent accidents at different stages of transmission: one to the archetype, which everyone inherited, and one to a later branch, which only Luke inherited. The two-stage story is not incoherent, but it doubles the cost — the expansion theory posits no accidents at all, while the damage account now needs two. The Great Omission and the abrupt ending stand or fall on different evidence; they are not parallel cases of damage.

3.4 The Seam Falls Between Stories

A further argument from (Streeter, 1924) held that the Great Omission shows the marks of physical damage in the way Luke seems to lose contact with Mark in the middle of one pericope and regain it in another. The judgment depends, however, on where one locates the boundaries of Luke's contact and on the boundaries used to count pericopes. A closer look at the text changes the picture.

On Streeter's reading the supposed tear in Luke's exemplar fell after Mark 6:47 — Luke shows knowledge of Jesus dismissing the crowd, withdrawing to the mountain, and being "alone on the land," and this material surfaces at Luke 9:18 as "he was praying alone, his disciples were with him." On the present model the observation is granted and accounted for differently. Mark 6:46–47 is not a fragment Luke salvaged from damage; it was already in proto-Mark. It is transitional material — a brief notice that after the feeding Jesus dismissed the people and withdrew alone to pray — and some such transition had to stand in proto-Mark between the feeding and what followed it, since one pericope cannot simply abut another without a connecting sentence. Strip the walking-on-water and the rest of the expansion away, and proto-Mark reads naturally: the feeding and the twelve baskets, the dismissal of the crowd and the withdrawal to pray alone, and then they come to Bethsaida and a blind man is brought to him. The expansion built the walking-on-the-water into this existing transitional space, taking the proto-Markan notice of Jesus alone and developing it into the theophany on the sea. Luke received the proto-Markan transition and reproduced it; what Streeter read as the upper edge of a tear is on our model the proto-Markan bridge over which Luke crossed when he omitted the Bethsaida healing.

The block, with this seam properly located, is not a uniform stretch but a series of relatively self-contained story-blocks linked by brief transitional sentences — typically a single sentence carrying the characters from one episode to the next. Wherever one places the proposed tear, both of its edges fall on these connecting sentences: at the upper edge, on the transition that follows the feeding; at the lower edge, on the brief notice that they came to Bethsaida and a blind man was brought to Jesus (Mark 8:22). Both edges land on transitions, not within stories.

This is improbable on a random-damage hypothesis. The transitions between stories make up a small fraction of the text; the stories themselves make up the great majority. A tear falling at random would be expected to land inside a story at each end — the abrupt mid-sentence interruption that is the normal signature of physical damage in a textual witness. For both edges of the tear to fall on the short transitional sentences, leaving the story-blocks themselves intact at both boundaries, requires either a low-probability coincidence or a torn text whose breaks have been smoothed by the copyist.

If smoothing is invoked, the damage theory loses what it most needs. Its strength has always lain in the claim that Luke transparently transmits the damage in his exemplar — that the gap in Luke is a window onto a physical defect in the text he used. The moment Luke is allowed to repair or smooth the broken edges, his text no longer transparently shows the damage, and the position becomes "Luke had a damaged copy and produced a clean text" — at which point there is no longer any evidence in Luke for the original damage at all, and the theory rests on nothing the text can support. Either Luke is the faithful witness the theory needs and the tear is improbably clean, or he is the editor the theory does not allow and the cleanness of the seam ceases to be evidence of damage.

The expansion hypothesis has no such dilemma. On our view there is no tear and no transition to smooth: proto-Mark already read continuously from the feeding through the dismissal-and-prayer transition to the Bethsaida healing, and Luke received and reproduced that continuous text.

3.5 The Cross-Reference

The block displays internal cross-reference. At 8:19–20, well inside the expansion, Jesus rehearses both feedings — the five thousand of proto-Mark and the four thousand of the expansion — pressing the disciples on the difference between the twelve baskets and the seven, and, in the Greek precisely, between the κόφινοι of the first and the σπυρίδες of the second. On our hypothesis the author has here reached back across the seam to bind his new material to the old. The cross-reference is the place where the addition acknowledges the inheritance it was joined to, and the seam where the two strata are visibly held together by the hand that composed the second. This by itself refutes any "doublet by accident" view of the four thousand — the view that it was an unintended scribal or transmissional duplication (Fitzmyer, 1981). Combined with the arguments above that this material is expansion, it shows the expansion to be a composed one.

The passage also bears on the intentional-omission view. The most common form of the intentional-omission argument holds that Luke dropped the four thousand as a redundant duplicate of the five thousand. But Mark himself does not regard them as duplicates: 8:19–20 is composed precisely to insist that the two feedings differ — in their numbers, in their baskets, in their very vocabulary. An omitter who treated as redundant what Mark himself rehearses as significantly distinct would be reading the gospel against its grain. The point does not refute intentional omission as such — other motives might be supplied, and the case against those has been made above on different grounds — but it removes the easiest and most common motive a defender might offer.

3.6 The Bethsaida Gap in Mark

A further argument is available without any appeal to Luke at all. In canonical Mark the Twelve depart for Bethsaida at 6:45 and arrive at Bethsaida at 8:22. Between the departure and the arrival lies the entire expansion block. This is an oddity unique to this stretch of the gospel. Mark's other journeys do not behave this way. Where the text records a departure for a named place, it records the arrival there directly afterward, or — more commonly — the characters simply go somewhere without a separate departure verse. Mark 5:1 has them arrive at the Gerasenes immediately after departing at 4:35; the Tyre and Decapolis legs of 7:24 and 7:31 each resolve at once; the journey-to-Jerusalem sequence in chapter 10 moves in short stages. Nowhere else in Mark do the disciples set out for a destination and reach it only many pericopes later, after an unrelated chain of intervening events.

The anomaly is sharpened by what happens in the middle. The boat does not in fact reach Bethsaida on the 6:45 departure. The walking on the water intervenes, and the disciples land instead at Gennesaret (6:53) — not the destination they were set toward. The original journey is thus not only suspended but redirected: a departure for one place, an arrival at another, and only later, after further intervening material, a fresh arrival at the original destination. Whatever the literary effect intended, this is the structural fingerprint of insertion rather than of continuous composition.

The point can be put in counterfactual form. Suppose we had no access to Luke at all. Searching Mark for possible late insertions, one of the things we would look for is exactly this — a stretch where the narrative connects more cleanly without the intervening material than with it, where a departure and an arrival appear to belong together but are separated by a long detour, where the surface story has had to be re-routed to accommodate a block. The Bethsaida span supplies that signature. Combine it with the unified pro-Gentile theme of the intervening material, and we would already have sufficient grounds, internal to Mark itself, to argue for a late expansion of this exact stretch.

Luke's independent witness then becomes decisive rather than primary. The internal-Markan argument identifies the suspected expansion on structural and thematic grounds alone; Luke's lacking the same block, in the same boundaries, with no contact except at the Bethsaida seam itself, then confirms what the internal evidence already suggested. Two independent lines — the Markan structural anomaly and the Lukan distribution — converge on the same boundaries of the same block. The damaged-exemplar theory must explain both the structural anomaly and the Lukan absence, and explain them as unrelated coincidences. The expansion theory explains both as a single act: the proto-Markan departure-to-Bethsaida and arrival-at-Bethsaida ran consecutively; the expansion was inserted between them; Luke's branch never received the insertion.

3.7 Conclusion – a Composed Expansion

The arguments against the two omission theories now converge, and they converge from two independent directions — the internal structure of Mark itself, and the distribution of the material across the synoptic tradition.

From within Mark, two features mark the block as inserted. The Bethsaida span is structurally anomalous: the disciples depart for Bethsaida at 6:45 and arrive only at 8:22, with the whole block between, and with a redirected landing at Gennesaret in the interim — a departure-and-arrival broken apart in a way no other Markan journey is. And the cross-reference at 8:19–20, in which the author rehearses both feedings and insists on their distinction, shows the block to be built rather than accumulated, and binds the new material to the old across the seam. These features, combined with the unified pro-gentile expansion this study argues, would suggest a late expansion of this exact stretch even if Luke did not exist.

From the distribution, the same boundaries are independently fixed. The block is present everywhere but Luke's line — Matthew has it, the manuscript tradition transmits it — as the stemma requires and as physical damage cannot economically explain. The Bethsaida seam, long the omission theory's best evidence, marks Luke's contact with a single proto-Markan pericope, the blind-man healing, rather than with the block; strip the expansion away and proto-Mark runs continuously from the departure for Bethsaida to the arrival there, the two references are consecutive.

The two lines meet on the same block with the same boundaries. The economics of the papyrus roll make a single spliced section the natural form a single author's expansion would take; a run of independently dropped pericopes would not be expected to fall in an unbroken row; and the material Luke would have welcomed, standing inside the block, forbids recasting the omission as one wholesale rejection. Damage must treat the Markan structural anomaly and the Lukan absence as unrelated accidents; intentional omission must supply a motive the content withholds and an editorial clumsiness Luke does not elsewhere display. The expansion hypothesis treats both as a single act — proto-Mark ran continuously from feeding to Bethsaida healing; the author inserted the block between them; Luke's branch, descending from proto-Mark, never received it.

4.1 The Two Feedings: The First Composed Pair

If the Great Omission is a composed stratum rather than a damaged one, the two feedings are where the composition is easiest to see, because here the expansion has left its method on the surface. Mark narrates the same miracle twice — a multiplication of loaves and fish for a crowd in a deserted place, with surplus gathered into baskets — and the modern reader's first instinct, that one is a clumsy doublet of the other, is precisely the instinct the text was built to correct. The two are not redundant. They are a matched pair, the first set in Jewish terms and inherited from proto-Mark, the second set in Gentile terms and supplied by the expansion, and the gospel itself, at the climax of the sequence, stops to insist that the difference between them is the point.

4.2 The Twelve: Sending and Appointing

The next two paired structures concern the Twelve themselves, and it is the pair in which the expansion's governing scripture comes most clearly into view. Mark twice constitutes the Twelve: he appoints them on the mountain (3:13–19) and he sends them out (6:7–13). Read together, the two acts carry the program of the whole expansion. The sending dispatches the Twelve to Israel — the inherited mission, Jewish in scope. The appointment reconstitutes that same body under a different sign: twelve still, for the tribes of Israel, yet commissioned now, by the logic of the Servant-scripture the scene invokes, to reach beyond Israel to the nations. The inherited act sends the Twelve to the tribes; the added act makes them, in Isaiah's own terms, a light to more than the tribes.

4.3 The Sea: Storm and Walking, the First and the New Exodus

The third pair takes the same structure — an inherited episode and an added one — onto the water, and its axis is the disclosure of who Jesus is. Here the expansion does not supply a Gentile counterpart to a Jewish scene, as the feedings did; it escalates the Christology of the inherited miracle from the first Exodus to the new, and by the logic of the new Exodus's own scripture, established at the Twelve, carries the gospel's reach toward the nations. The pair's primary axis is Christological; its Gentile bearing is consequent upon that, not independent of it.

4.4 The Senses: Sight and Hearing, Israel and the Nations

The last of the paired structures concerns the opening of the senses — a blind man given sight, a deaf man given hearing — and it divides along the proto-Mark/expansion line as cleanly as the feedings, once the two members are correctly assigned. The healing of the blind man at Bethsaida (8:22–26) is proto-Markan: Luke had it in his source and omitted it, as argued above, from discomfort with its two-stage, saliva-mediated technique, the displaced place-name surfacing at Luke 9:10 as the trace of his contact with it. The healing of the deaf man of the Decapolis (7:31–37) is expansion: Luke never received it. The inherited member gives sight; the added member gives hearing; and the distinction between the two senses carries, in compressed form, the whole salvation-historical claim of the expansion — that Israel saw and the nations hear.

4.5 The Pairs as Proof of Composition

With the four pairs before us, the argument they jointly carry can be stated plainly, for it is the strongest evidence that the expansion was composed rather than lost or excised. In three of the four, the inherited Israel member survives in Luke's gospel while only the added Gentile member is absent: Luke has the five thousand but not the four thousand, the storm but not the walking on the water, the sending of the Twelve but not the framing of the appointment under the Servant's call. The material missing from Luke is therefore not a thematically random stretch, nor even simply a pro-Gentile stretch, but the Gentile member of a matched set whose Israel members Luke continues to attest.

No accident produces this. A lost leaf removes whatever text occupies a span of the roll; it cannot single out the four thousand while sparing the five thousand, or the new-Exodus sea-crossing while sparing the first, for a tear does not know which member of a pair is the Jewish one. Nor does deliberate omission account for it, except by crediting Luke with exactly the pair-by-pair surgery the hypothesis attributes, in reverse, to Mark's expander: a Luke who recognized each doublet and struck only its Gentile half, while retaining its Israel half in place. The one process that does produce a series of Gentile members built upon inherited Israel members is the process this study has described: an author expanding proto-Mark, composing for each retained Israel episode a Gentile counterpart. It is Luke's retention of the inherited members that makes the design legible; without the surviving Israel halves we could not see that what Luke lacks is, every time, the half that turns to the nations.

The fourth pair, the two healings of the senses, stands slightly apart and must be stated carefully, for here Luke attests neither member directly: the deaf-mute (the nations' hearing) belongs to the expansion and is absent, while the blind man (Israel's sight) belongs to proto-Mark yet was dropped by Luke — recoverable in his text only as the displaced place-name Bethsaida, the trace of a pericope he received and declined for its two-stage, spittle-mediated cure. The senses pair thus shows the expansion's hand — but it cannot show it in the way the other three do, by the survival of the Israel member alongside the absence of its Gentile twin.

4.6 The Isaian Architecture of the Expansion

The four pairs have been read each on its own terms, but they share a scriptural substructure that becomes visible only when they are set side by side, and that substructure is the strongest evidence that the expansion is a single composed program rather than an accumulation of Gentile-friendly episodes. In each pair the inherited, proto-Markan member is keyed to the first Exodus — to Moses, the wilderness, the deliverance of Israel — and the added, expansion member is keyed to the new Exodus of Isaiah, the restoration that Deutero- and Trito-Isaiah declare will reach beyond Israel to the nations. The expansion does not merely add Gentile material; it adds material drawn from one identifiable region of scripture, and it sets that material against the Mosaic typology of the layer it was joined to.

The distribution is consistent across the pairs. In the feedings, the five thousand (proto-Mark) is the manna of Exodus 16, Israel's wilderness ration in its very measure, gathered into the twelve baskets of the tribes; the four thousand (expansion) feeds those "from far off" (ἀπὸ μακρόθεν, 8:3), the phrase by which Isaiah names the nations gathered from the ends of the earth (Isa 49:12; 57:19). In the constitution of the Twelve, the sending (proto-Mark) provisions a mission to Israel's lost sheep in the manner of the wilderness; the appointment (expansion) constitutes the Twelve under the second Servant Song, called and named as the Servant is called and named (Isa 49:1), and so under the declaration that to raise up the tribes of Jacob is "too light a thing," the Servant being given as "a light to the nations, that my salvation may reach to the end of the earth" (49:6). In the sea-miracles, the stilling of the storm (proto-Mark) is the mastery of the waters in the mode of the first deliverance; the walking on the water (expansion) is the new Exodus of Isaiah 43 — the way through the sea, the "new thing" that the hardened of heart cannot perceive, and the ἐγώ εἰμι by which Isaiah's God declares himself (43:10, 16–19). In the senses, the blind man of Bethsaida (proto-Mark) gives Israel its halting, partial sight; the deaf man of the Decapolis (expansion) gives the nations their hearing, in the words of Isaiah 35, the man named μογιλάλος after the rare word that, in the sense of a healed impediment, is distinctive to Isaiah 35:6.

To these four the fig-tree pericope, treated below, adds a fifth instance of the same hand. The cursing of the temple's fruitless tree (expansion) frames the temple's judgment with the one prophetic oracle of Gentile worship — "my house shall be called a house of prayer for all the nations" (Isa 56:7) — the universalist clause that Matthew declines to preserve, and that Luke never saw. Across five expansion units, then, the controlling scriptures are Isaiah 35, 43, 49, and 56: a single body of prophetic material, and not a random sampling of it.

That this body is coherent, and that Mark's selection from it is principled rather than opportunistic, is the point on which the whole architecture turns, because the obvious objection is that Isaiah is long and rich in nations-material, so that a verse can be found to suit any pericope. The objection is answered by what the chosen texts have in common. They are not scattered across Isaiah; they cluster in the new-Exodus complex — the second half of the book together with the proto-apocalyptic chapter 35 that anticipates it — and within that complex they are precisely the passages in which the restoration of Israel overflows into the inclusion of the nations. That complex is not a unit defined here to fit the argument; it is a recognized division of the book, identified by Isaiah's interpreters on grounds internal to Isaiah and without reference to any question about Mark. Isaiah 49 makes the gathering of Jacob "too light a thing" and turns the Servant to the Gentiles; Isaiah 56 admits the foreigner and the eunuch to the house of prayer for all nations; Isaiah 43's new thing is the new Exodus whose telos, in the Servant Songs that surround it, is the ends of the earth; Isaiah 35's healed senses are the signs of God's coming to save, breaking out, in Mark, on a Gentile.

The decisive point is not merely that the expansion clusters, but what it clusters away from. Isaiah's nations-material is not all of one kind: the book is equally full of oracles against the nations — the judgment cycle of chapters 13 through 23, Babylon and Moab and Tyre arraigned and destroyed — and that material is nations-language in abundance. The expansion draws on none of it. It confines itself, without exception, to the texts in which the nations are gathered in rather than judged. An author reaching at random for nations-language would have caught some of the judgment, for there is at least as much of it; this author caught only the ingathering. The principle of selection is thus single and visible, and doubly so: the expansion draws on the Isaian texts in which Israel's new Exodus is declared to be for the world, and it leaves untouched the equally available texts in which the world is condemned.

Two honest qualifications keep the architecture within its limits. First, the first-Exodus/new-Exodus division between the layers is a strong tendency, not an exceptionless law: the inherited blind-man healing latently shares the Isaiah 35 frame that the added deaf-man healing makes explicit (the same oracle opens both eyes and ears), and the storm-stilling draws as much on the Psalter's mastery of the sea (Ps 107:23–30) as on the first Exodus proper. The claim is that the expansion systematically makes explicit and verbally anchors an Isaian new-Exodus reading, against a proto-Markan layer that is Mosaic in its typology and only latently Isaian — the expansion intensifying and systematizing an orientation already present in the earlier text. Second, "Deutero-Isaiah" and "Trito-Isaiah" are modern designations; Mark knew Isaiah as one scroll, and the claim is not that he cited a recognized division but that he drew, with evident deliberateness, on the thematically unified new-Exodus-and-nations material that modern scholarship locates in the book's later chapters and in chapter 35.

Within those limits the conclusion stands, and it is the capstone of the case for the pairings. The expansion is not a series of separately motivated additions that happen to favor the Gentiles. It is a single Isaian program: against the first Exodus of the inherited gospel — Moses, manna, the gathering of the tribes — the expansion sets the new Exodus of Isaiah, in which the God who made a way through the sea does a new thing, opens the ears of the nations, and gives his Servant as a light to the ends of the earth. The Gentile telos of the expansion is not imported by the modern reader; it is Isaiah's own, and the author of the expansion has built his additions upon it.

4.7 The Rest of the Great Expansion

We now turn to the non-paired parts of what we will now call the “Great Expansion”.

5.1 The Criteria

The Beelzebul controversy meets the position criterion strictly. Luke has the corresponding material at 11:14–23, in the travel narrative — the long central section (9:51–18:14) into which Luke gathers his non-Markan material from the sayings source and from Matthew. This is the part of Luke's gospel where Markan material does not live, and the placement of the Beelzebul material there is positive evidence rather than mere absence: it stands precisely where material drawn from Matthew or the sayings source would be expected to land, and conspicuously not where it would land had Luke been following his Markan source. The Markan position at 3:22–30 is not merely unattested by Luke; the controversy is located in his gospel at a position that betrays its non-Markan source.

The appointment of the Twelve meets the position criterion more loosely. Luke 6:12–16 places the appointment close to where Mark 3:13–19 has it — both fall shortly after the healing of the paralytic. The slight difference in placement is intelligible on our model, and is best shown by setting the reconstructed sequences side by side.

On our model, proto-Mark ran roughly: the paralytic is healed; the Twelve are called; Jesus departs with them to the sea; the crowds press in; a boat is made ready; unclean spirits are rebuked; he enters the boat and teaches from it; true family is those that do the will of God, then he departs by boat.

Luke, following that inherited structure, runs: the paralytic is healed; the Twelve are called; Jesus goes down with them to a level place; the crowds gather; unclean spirits are rebuked; he teaches at length; and — after the intervening material Luke has gathered here — we have the “true family” and he departs by boat at 8:22. The chief structural change is that Luke sets the teaching on a plain rather than in a boat. (The stretch of Lukan material between the teaching and the boat departure is considerable; what the parallel claims is a shared skeleton — paralytic, Twelve, crowds, healings, teaching, family, boat — not an unbroken adjacency.)

Canonical Mark, we suggest, reworked the inherited sequence at this point: the paralytic is healed; (the old call of the Twelve is crossed out); Jesus departs with the Twelve to the sea; the crowds press in; a boat is made ready; unclean spirits are rebuked; and here the expansion is spliced in — the reframed appointment of the Twelve and the Beelzebul controversy and Jesus’s true family as a frame to Beelzebul — after which he enters the boat, teaches from it, (the old “true family” sentence is crossed out)⁸ and departs by boat.

The appointment is, on our model, the inherited calling of the Twelve, moved slightly and reworked into a formal constitution of the body; the constituting language and the Servant-naming are treated in §4.2.2. What concerns the criteria here is how the block divides under the wording test — and it divides, along the line between what the expansion added and what it inherited.

Luke shows no knowledge of canonical Mark's wording of the Beelzebul controversy itself. He agrees with Mark only where Mark and Matthew themselves agree; at every point where the two diverge, Luke follows Matthew or supplies his own wording. A single substantive exception — Luke and Mark read "Holy Spirit" against Matthew's plain "Spirit" — is readily explained as Lukan style, the fuller phrase being a marked Lukan preference attested throughout the Gospel and Acts. Luke is handling this material in a non-Markan stretch of his gospel, with no other contact with the Markan text nearby, so the agreement on "Holy Spirit" is better read as Lukan idiom than as Markan dependence.

In the appointment Luke does not attest the expansion's framing additions — the imposed names, "Boanerges," the whole weighted conferral; he retains only a single plain naming (6:14). Yet at one point he agrees with Mark against Matthew: the disciple list pairs "Matthew" and "Thomas" in the same order in Luke and Mark, against Matthew's own "Thomas and Matthew the tax collector." The two facts fit together on our reading. What Luke lacks is precisely the expansion's frame; what Luke preserves — the bare list, in its Markan order — is precisely the proto-Markan substrate the expansion built upon. Luke's silence falls on the added frame, his agreement on the inherited core. The wording criterion is thus satisfied for what the expansion added, while the received list survives in Luke as its proto-Markan base.

For size, the criterion is met without caveat: two successive pericopes form the contiguous block — and they are not merely adjacent but thematically interlocked, the appointment's grant of exorcism authority (absent from Luke) setting up the Beelzebul controversy that defends it (§4.2.2).

5.2 The Synoptic-Problem Argument

The synoptic-problem case for treating the Beelzebul controversy as non-Markan is set out in our previous study (Gentile, 2026a); here it is enough to recall its result and its bearing on the present reconstruction. The difficulty the passage poses for the Two-Source Hypothesis is that it must be handled as a Mark–Q overlap, yet the Q reconstructed for it turns out to reproduce Matthew's own wording — so that "Q," in this passage, becomes indistinguishable from Matthew, and positing it explains nothing that Luke's direct use of Matthew would not. The plain reading of the evidence, taken by itself, is a simple chain: Mark, then Matthew, then Luke.

What matters for the expansion hypothesis is the coincidence that any Luke-had-canonical-Mark account must absorb. On such an account Luke, in this one passage, departed from both Mark's order and Mark's wording at once, when he could have done either alone. The proto-Mark reconstruction dissolves the coincidence rather than absorbing it: there was no Markan version for Luke to depart from, because the controversy was not in the Mark his line received. His dual silence — no Markan position, no Markan wording — is then not a double editorial choice but a single fact about his source, and it is exactly the silence the expansion hypothesis predicts. Luke has done everything he possibly could to tell us he never saw this material.

5.3 The Blasphemy Saying

A further detail confirms the source-chain. Both Mark (3:28–30) and Matthew (12:31–32) follow the Beelzebul controversy with the saying on blasphemy against the Holy Spirit; Luke omits it from the Beelzebul context, where it would have followed 11:23, but has the saying later, at 12:10. A form of it also appears in Thomas 44, consistent with its circulation in the sayings tradition independently of the narrative Beelzebul setting. On our model the explanation is straightforward: the saying already stood in the proto-Luke spine at 12:10, drawn from the sayings source, before Matthew's Beelzebul material was worked in. Incorporating that material into his framework, Luke reached the blasphemy saying and, finding it already present in his existing text, passed over it rather than duplicating it. He is following Matthew's text until he meets a unit already fixed in his spine — and the omission marks exactly the seam between his two sources.

5.4 A Second Internal Seam: The Boat

The Bethsaida gap is not the only internal-Markan trace of the expansion. The Beelzebul block displays the same structural fingerprint. At 3:9, immediately before the expansion block begins, Jesus instructs his disciples "to have a boat ready for him because of the crowd, lest they should crush him." The boat is prepared, and the narrative reason for the preparation is explicit: the press of the crowd by the lakeshore. Then the expansion intervenes — the appointment of the Twelve on the mountain (3:13–19), the family scene and Beelzebul controversy (3:22–30) — none of which involve the boat or the lakeshore at all. The mountain is the wrong location, and the controversy with the scribes and his own family takes place in a house. When the narrative returns to the lake at 4:1, the boat is at last used: Jesus gets into the boat and teaches from it because the crowd is too large to gather around him on shore.

The setup and the payoff belong together. Read continuously, proto-Mark connects 3:9 directly to 4:1: "and he told his disciples to have a boat ready for him because of the crowd, lest they should crush him… and a very large crowd gathered about him, so that he got into a boat and sat in it on the sea." The intervening material in canonical Mark — the mountain appointment, the indoor family scene, the controversy — has displaced the boat preparation from its narrative payoff, just as the expansion displaces the departure for Bethsaida from the arrival at Bethsaida. The pattern is the same. Strip the expansion away and the boat instruction is followed directly by the boat being used; leave the expansion in and the instruction is given, the narrative wanders elsewhere for two full chapters of material, and the boat is used only after a long delay.

As with the Bethsaida case, this argument requires no appeal to Luke. Searching Mark for possible late insertions, one of the things we would look for is exactly this — a stretch where a narrative setup waits for its payoff across intervening material that has nothing to do with the setup. The Beelzebul block supplies that signature, and supplies it on the same pattern as the Great Omission. Luke's independent witness then converges on the same boundaries: the appointment of the Twelve at near-Markan position (the proto-Markan inheritance Luke received), the Beelzebul controversy displaced to the travel narrative where Luke's non-Markan material lives (the expansion content Luke never had in Markan form), and the parables discourse resuming after the block in Markan position and wording (proto-Markan inheritance again).

Two independent boat seams in two independent expansion blocks — the Bethsaida journey broken at 6:45–8:22, and the boat instruction broken at 3:9–4:1 — is more than coincidence. It is the recurring trace of a hand inserting material into a continuous narrative, leaving the original setups and their delayed payoffs as the scars of the insertion. The expansion has not just added material; it has interrupted ongoing journeys and waiting boats, and the interruptions can be read off the surface of Mark itself before any synoptic comparison is undertaken.

5.5 The Pro-Gentile Reading

The controversy, read within the expansion, addresses the question that haunts the whole Gentile mission: by what authority does Jesus cross the boundaries the Torah and the Pharisaic tradition have set? The opponents' answer is that he does so by demonic power — "he has Beelzebul, by the prince of demons he casts out the demons" (3:22). Jesus's reply turns the charge inside out. He is not Satan's agent but Satan's conqueror: "no one can enter a strong man's house and plunder his goods unless he first binds the strong man" (3:27). Far from operating by the prince of demons, Jesus has bound him and is despoiling his house — and in the Pauline frame the expansion works within, the house the strong man held is the domain of the nations, long under the power of the adversary and now being plundered back. (Paul names exactly this conquest: God "disarmed the rulers and authorities, triumphing over them," Col 2:15; the risen Christ sends Paul to turn the Gentiles "from the power of Satan to God," Acts 26:18.) The reply closes with its sharpest edge — that to attribute the Spirit's work to demonic agency is the one unforgivable blasphemy (3:28–30), the charge turned back on the accusers. The reading of the plundered house is the program's, not the surface's — the saying speaks of a strong man and his goods, not of the nations — but it is of a piece with everything the expansion elsewhere makes explicit. The Markan setting confirms the direction: the controversy is intercalated between the family's coming to seize him as "out of his mind" (3:20–21) and the redefinition of family as those who do God's will (3:31–35), so that natural kin who reject him are set against the new family of those who follow — the very shape of the Gentile mission, rejected by his own and acknowledged from outside. The Beelzebul controversy is thus the expansion's narrative defense of the mission: the boundary-crossing is not the work of a foreign spirit but the plundering of the strong man's house, and the new family it creates is the mission's fruit.

The companion piece is the appointment of the Twelve under Isaiah 49 — treated in a previous section — which constitutes the body whose Gentile commission the controversy defends. Together they form the second secure block of the expansion, the Beelzebul controversy answering the objection and the appointment naming the commission.

6.1 A Third Internal Seam: The Jerusalem Sequence

The Bethsaida gap and the boat at 3:9 are not the only internal-Markan traces of the expansion. The fig-tree intercalation has left a still more conspicuous seam in the geography of Mark 11, visible without any appeal to Luke. The sequence as canonical Mark presents it sends Jesus and the Twelve in and out of Jerusalem in a way that makes sense only if the fig-tree frame is present; remove the frame, and the journeys collapse into a single coherent visit.

In canonical Mark the triumphal entry brings Jesus to Jerusalem and to the temple, where, surprisingly, he does nothing: he "looked around at everything" and, "since it was already late," withdrew to Bethany with the Twelve (11:11). The next morning, leaving Bethany, he curses the fig tree (11:12–14); the party returns to Jerusalem and he cleanses the temple (11:15–19); in the evening they go out again; the following morning they pass the fig tree, find it withered, and only then — at 11:27 — re-enter Jerusalem to face the chief priests.

Three things in this sequence are strained, and all three are relieved at once by removing the fig tree. The first is the flatness of the entry's climax. A triumphal procession builds toward a deed at its destination; this one arrives at the temple, observes, and withdraws — the note that “it was already late” (11:11) having the air of a writer accounting for a deferral he has himself introduced.

The second is the cleansing's displacement to the following day. The natural shape would put the cleansing on the day of the entry; the expander could not, because his frame required the tree to be cursed immediately before the cleansing, in order to enclose it. The sequence had to be: entry, fig tree, cleansing. So the cleansing was pushed to the second day and the late hour invented to cover the gap. Matthew's handling points the same way: working from canonical Mark, he restored the cleansing to the day of the entry (Matt 21:12) and set the fig tree after it as a standalone sign, withering at Jesus’s word the next morning (21:18–19). The intercalation that strains Mark's narrative is precisely what the next redactor undid.

The third strain is the plainest, and the hardest to explain any other way. The journey of the third day exists for no purpose but to walk the travelers past the tree a second time: out of the city in the evening, back the next morning to find it withered (11:20), after which "they came again to Jerusalem" (11:27). Nothing else happens on that circuit. Strip the fig tree away and the disciples have no reason to leave the city or to return; the entire out-and-back movement is an artifact of the need to view the tree twice.

Read continuously without the frame, proto-Mark gives a single day in Jerusalem: the triumphal entry, the immediate cleansing, and the confrontation with the chief priests, all in one visit. The three-day structure of canonical Mark is entirely an artifact of the fig tree — the evening withdrawal and morning return exist only to curse the tree on the way in and find it withered on the way out. Remove the tree and the days collapse with it: there is no reason to leave Jerusalem and return, and the authorities who resolve to destroy him at the cleansing (11:18) confront him directly (11:27), on the same day, with nothing intervening. The strains are not in that narrative; they appear only once the fig tree is woven through it. As at Bethsaida and at the boat of 3:9, the expansion is detectable in the surface of Mark itself — the deferred action, the manufactured explanation, the redundant journey are the scars of an insertion the text still bears. Three independent internal seams, in three independent expansion blocks, are far harder to dismiss as accidents of literary structure than any one would be.

6.2 The Old Testament Background

That the fig tree carries a symbolic charge is not a premise this argument must defend; it is the consensus reading of the passage. The fruitless or withered fig tree is standard prophetic shorthand for Israel under judgment for covenant failure (Jer 8:13; Hos 9:10; Mic 7:1; Joel 1:7), and the flourishing vine-and-fig-tree is the corresponding figure of covenant peace (Mic 4:4; Zech 3:10; 1 Kgs 4:25). The enacted-judgment reading of Mark 11 — the barren tree as a prophetic sign-act against a fruitless Israel — is the mainstream interpretation.¹⁰

The one feature of the text that has troubled interpreters, Mark's parenthetical "for it was not the season for figs" (οὐ γὰρ ἦν καιρὸς σύκων, 11:13), tells in favor of the symbolic reading rather than against it. On any horticultural construal the curse is arbitrary, even unjust: the tree is condemned for lacking fruit out of season. The note functions precisely to block the literal reading and to redirect the reader toward the sign it enacts. The episode is not about a tree.

6.3 The Intercalation as Expansion Construction

The fig-tree halves, absent from Luke in both position and wording, were wrapped around a cleansing that already stood in the proto-Markan text, converting a freestanding temple demonstration into an intercalation. And the conversion is interpretively decisive, for Markan intercalation makes the frame and the filling read each other. The barren tree, cursed for bearing no fruit, becomes the figure of the temple, and the temple, judged at the center, becomes the meaning of the withered tree. The fruitless tree is the fruitless cult; the tree withered to its roots (11:20) is the temple under sentence. This reading of the intercalation is not novel — it is the mainstream interpretation of the passage — but on the present reconstruction it is also the expansion's own construction: proto-Mark had a cleansing that provoked the authorities to seek Jesus's death; the expansion made that cleansing the center of a sign-act pronouncing the temple barren.

The temple so judged is judged, in Mark's text, under a particular scripture. At the heart of the cleansing Jesus states the charge: "Is it not written, 'My house shall be called a house of prayer for all the nations' (πᾶσιν τοῖς ἔθνεσιν)? But you have made it a den of robbers" (11:17), joining Isaiah 56:7 to Jeremiah 7:11. The first citation is the one prophetic oracle that envisions the temple as a place of Gentile worship — Isaiah 56 admits the foreigner and the eunuch to the house of God — and it is the universalist clause "for all the nations" that carries the cleansing's pro-Gentile sense.

The clause "for all the nations" is most economically assigned to the expansion, for three reasons. First, it bears the expansion's distinctive theme — the inclusion of the nations — in the expansion's distinctive idiom, the Isaian Gentile-oracle, the same register that supplies "a light to the nations" at the appointment of the Twelve (Isa 49:6) and the gathering of those "from far off" at the feeding of the four thousand. Second, it forms a single editorial gesture with the fig-tree frame: the brackets turn the cleansing into a temple-judgment, and the clause makes that judgment specifically a judgment of the temple as the house of prayer for all nations that it failed to be. Third, the clause is absent from Luke — and that absence, on our method, is itself evidence of its origin. Had "for all the nations" stood in proto-Mark, proto-Luke would have carried it over, and it would stand in canonical Luke today; its absence there indicates it was not in the proto-Markan text. The one alternative — that Luke received the clause and deliberately dropped it — we can exclude, for Luke is the most Gentile-minded of the evangelists, given to enlarging rather than suppressing the welcome of the nations (2:32; 4:25–27; the whole trajectory of Acts). He is the last writer who would strike out "a house of prayer for all the nations" had he found it. His silence is therefore not omission but source-absence, and source-absence places the clause in the expansion¹¹.

One further datum corroborates the clause's expansion. Matthew, who on the present model worked from canonical Mark, had the full quotation before him and altered it: Matthew 21:13 reads simply "a house of prayer," striking "for all the nations" while keeping the "den of robbers" charge from Jeremiah. The removal is selective, not an abbreviation — he retained one half of Mark's paired citation and cut only the other, the universalist half — which marks it as targeted, the same defusing of the expansion's Gentile material seen elsewhere in his redaction.

The sayings appended after the withered tree (11:22–25), where Luke also shows no direct knowledge of the Markan text, and on our model part of the expansion, describe what stands in the temple's place: faith in God, the casting of "this mountain" into the sea, prayer that needs no sacred precinct, and mutual forgiveness as the condition of being heard. "This mountain," given the setting, is plausibly the temple mount itself, though the phrase is not decisive. This is a portable, non-cultic piety: access to God by faith and prayer rather than by sacrifice or sacred place. Read against the program of this study, it sketches in miniature the community that the Gentile mission presupposes — one whose standing before God does not run through the temple or its law. The consonance with Pauline theology, access by faith apart from the cult, is a claim of theological affinity rather than literary dependence, and it has a respectable place in the scholarship that reads Mark as broadly Pauline in sympathy (Marcus, 2000a).

6.4 Fig Tree Conclusion

The fig-tree intercalation, visible in Mark’s internal seams, thus belongs to the expansion's anti-cultic strand, in which the Gentile orientation appears by way of the temple's supersession rather than on the narrative surface. The cult that had excluded the nations — the court of the Gentiles given over to the traders Jesus drives out — is pronounced barren, and pronounced barren under the scripture that had named it a house of prayer for all nations. The temple's failure is its failure toward the Gentiles, and the withered tree is the sign of it. The sayings that follow then describe what comes after — faith, prayer, and forgiveness as the standing of a community that does not need the temple — sketching in miniature the Gentile-inclusive community the expansion as a whole envisions. That the pro-Gentile sense is delivered through an anti-cultic judgment, legible only against Isaiah 56 beneath the text, is characteristic of the expansion's manner, and is taken up in the account of the gospel's esotericism reserved for a forthcoming study. (Gentile, 2026c)

7.1 Mark 12:28–34 — The Greatest Commandment

This candidate is the one where the source-critical picture is richest. First, we can note that Luke has this at a non-Markan location, satisfying one criterion. Next, we can note that Luke shows no agreement with Mark’s wording against Matthew. The double love-command is shared by all three Synoptics, but the form in which Luke carries it (10:25–28) shows no dependence on Mark — it is built, rather, from Luke's other sources, the Septuagint, the sayings source (through proto-Luke), and Matthew. Two features establish this. The first is the framing. In Mark the questioner is a scribe (γραμματεύς) who approaches sympathetically, having seen that Jesus "answered well," and whom Jesus commends as "not far from the kingdom" (12:28, 34). In Matthew he is a lawyer (νομικός) who comes "testing" Jesus (πειράζων, 22:35), and the commendation is gone. Luke's questioner is likewise a lawyer (νομικός) who stands up "to test" him (ἐκπειράζων, 10:25) — the title and the hostile intent agreeing with Matthew against Mark, not with Mark. The second is the wording of the commandment itself. The Septuagint of Deuteronomy 6:5 names three faculties; Mark expands them to four, "heart, soul, mind, and strength," a fourfold form unknown to any Old Testament text; Matthew keeps three, "heart, soul, and mind." Luke has four — but his fourth element is exactly what the conflation of his sources would yield: "strength," which the Septuagint supplies and Matthew (and likely the sayings source) lacks, joined to "mind," which Matthew supplies. That Luke's order inverts Mark's — "strength, mind" where Mark has "mind, strength" — is the tell. A writer copying Mark would have small reason to transpose the pair; a writer assembling the list from the Septuagint and a Matthew-like source, neither of which presents the four in Mark's sequence, naturally arrives at a different order. Luke's commandment is a conflation of his sources, not a memory of Mark's. Thus, the first two criteria that govern the secure blocks apply: Luke attests neither its Markan position nor its Markan wording.

What singles this pericope out as expansion material is its uniquely Markan coda. The scribe's rejoinder (12:32–33) does not merely affirm the two commandments but ranks loving God and neighbor "more than all whole burnt offerings and sacrifices" — a subordination of the cult that Matthew and Luke alike lack, and that states the expansion's anti-cultic program almost as a thesis. A small touch sharpens it. Repeating the command back, the scribe does not echo Jesus's word but alters it: where Jesus said "mind" (διάνοια, 12:30), the scribe says "understanding" (σύνεσις, 12:33) — comprehension, insight, the faculty of putting things together. The substitution is Mark's, and it is pointed: the one who grasps that love outranks sacrifice is marked as one who understands, and understanding is, in this gospel, the faculty of those who perceive what the cult does not. On the surface the saying speaks only of love over sacrifice; read within the program the expansion has by now disclosed, the anti-cultic insight is of a piece with the turn to the nations — the sense Mark's surface conceals and his telling would have supplied.

This pericope also bears on the relationship between canonical Mark and the sayings source, and here the evidence runs deeper than the criteria alone. On the model argued here, canonical Mark did not originate the love-command; he took a simpler form of it from the sayings source and elaborated it for his own ends — the same borrowing traced elsewhere in this series (Gentile, 2026c), where Mark takes a saying the source supplied and drives it to the anti-cultic conclusion his program required. Two facts about Marcion's Evangelion support this. The first is that the pericope is attested there at all, in what our model takes to be its proto-Luke form: the sayings-source version, reaching Marcion through proto-Luke and owing nothing to Mark. The second is more pointed. Marcion's text does not attest "neighbor" here — it carries the love of God without the love of neighbor joined to it. That is precisely the form we posit for the sayings source, before canonical Mark's expansion welded the two commands together and set them above the cult. A Marcion presence is stronger evidence than a Marcion absence, since Marcion abridged but did not compose; that the pericope stands in his text, and stands there in the God-only form our stratigraphy predicts, is as close to confirmation as this kind of reconstruction affords.

The document tree then reads as follows:

Stage 1 – Proto-Mark does not have this pericope.

Stage 2 – The sayings source has a pericope like this. But it is only about love of God and not neighbor. Its wording is Matthew’s "heart, soul, and mind", and it does not contain the scribe’s reply or the subordination of the Temple cult.

Stage 3 – Canonical Mark utilizes this for his own purposes. He adds the language of “neighbor” and “burnt offerings and sacrifice” and “understanding” and “strength”.

Stage 4 – Proto-Luke is based only on the sayings source.

Stage 5 – Matthew works from canonical Mark and the sayings source. He shows features of both. He has Mark’s order, and Mark’s “neighbor”. Matthew retains the sayings source’s “heart, soul, and mind", and drops Mark’s subordination of the Temple cult and”understanding”.

Stage 6 – canonical Luke has the sayings source version through proto-Luke, and has access to Matthew. He adds “neighbor” here based on Matthew’s version. And he conflates the attribute list in his sources with the list from the Septuagint. He brings over Matthew’s lawyer who tests Jesus, as a framing.

Stage 7 – Marcion reflects the text of proto-Luke (and thus the sayings source).

This is a complex history, and one we need not have correct in every detail for the pericope to make its point. What it shows, on our model, is canonical Mark drawing a saying from the sayings source and turning what he found toward the subordination of the cult — the scribe's "more than all whole burnt offerings and sacrifices" being the expansion's own addition, not the source's. That canonical Mark should borrow from the sayings source in this way is not unique to this passage, a point taken up in the next paper of this series (Gentile, 2026c).

As a candidate for the expansion the pericope answers two of the formal criteria and carries the program; it falls short of the secure blocks only in being a single pericope rather than a large one, and in showing no internal seam of its own. On that basis it is the strongest of the smaller candidates, though it is held outside the formal reconstruction — not because its expansion status is in doubt, but because the secure list is confined to the large, seamed blocks.

7.2 Mark 14:3–9 — The Anointing

Luke's anointing scene (7:36–50) is a different episode in a different place, so the pericope satisfies both halves of the "no knowledge of Mark" criterion: Luke attests neither its Markan position nor its Markan wording. It is also absent from Marcion's Evangelion. Marcion is an imperfect witness — he abridged his text in places on his own account — so a single absence is corroboration rather than proof; but here it is consistent with the pericope's having been lacking in proto-Luke, and — as the criteria independently indicate — absent from proto-Mark.

The woman’s significance lies in the anti-cultic key the expansion sounds in the fig tree and the greatest commandment. What she performs is an anointing — and anointing is a priestly act, the rite by which kings and priests and the holy things were consecrated. Though the scene names the act a preparation for burial (14:8), the gesture itself carries the older resonance: the Messiah — the "anointed one" — is anointed not in the temple and not by a priest but by an unnamed woman, a layperson, in a private house, and the house of a leper at that, a place of ritual impurity. The true consecration of the Christ takes place entirely outside the cult. The expander's placement makes the point unmistakable. The pericope is set into the passion plot — the chief priests conspiring just before (14:1–2), Judas going out to betray just after (14:10–11) — so that the temple authorities' plot to kill the Messiah stands on either side of an outsider's act of consecrating him. The legitimate cult conspires; the marginal woman anoints. It is the same reversal the fig tree enacts against the temple, here compressed into a single scene.

On this reading the closing saying is the expander's signature rather than an isolated universalism: because the true anointing is freed from the temple, what the woman has done "will be told in the whole world, wherever the gospel is preached" (14:9). The extra-cultic act has worldwide scope — the Gentile reach following from the supersession of the cult rather than standing on its own. The reading is offered as affinity, not as a datum the pericope announces. The unit satisfies the first two criteria, sounds the program's anti-cultic note, and even shows a possible seam, interrupting the passion plot; but it forms no large block, and it is held outside the reconstruction accordingly.
