Type: supporting argument (off-timeline) · Assessment: sound — the Fathers routinely filed as "allegorists" read the Flood on multiple levels, affirming the historical event and building the figurative sense (ark = Church / Christ's cross) on it, not in place of it; and no named ancient Christian writer can be shown to have denied the Flood's historicity. The one real caveat is that Augustine attests a figure-only-no-history reading existed as a category in his day — he simply names no one who held it

See also: the historic-consensus thesis (assessment: sound), of which this argument tests sub-claims (i) "the pre-modern Church read the Flood as history, not pure allegory" and (ii) "no Saint denied it before the modern era."
Here the claim is a thesis about the history of interpretation: that the patristic allegory of the Flood layered figurative meaning atop an affirmed history rather than dissolving it, so that "allegorist" never meant "denier."
"Who was the first Saint to say the Flood story did not really happen?" — the challenge presumes the answer is no one: Origen, Clement of Alexandria, Ambrose, and Augustine are routinely filed as "allegorists," yet they read the Flood on multiple levels, affirming the historical event and its figurative sense. Calling them "allegorists" does not make them deniers of the history.
The challenge is a staple of popular debate over Genesis. The argument turns on a single equivocation: the assumption that to read a narrative figuratively is to read it instead of historically. Against that, the question is sharpened two ways — (a) did the patristic allegorists in fact retain the history under their figures? and (b) can any named ancient Christian writer be shown to have denied the Flood's historicity outright?
The substance of the thesis is a mainstream finding of the history of exegesis: that the patristic "allegorical" reading of the Old Testament was, with vanishingly few real exceptions, a both/and — the literal-historical sense first, the spiritual sense built on it. The strongest witness for it is the allegorists' own texts, and above all Augustine, who states the two-level reading as a rule and explicitly polices its boundaries against a figure-only reading.
Augustine states the rule and rejects both errors. In City of God 15.27 — the chapter whose very title is "Of the Ark and the Deluge, and that We Cannot Agree with Those Who Receive the Bare History, But Reject the Allegorical Interpretation, Nor with Those Who Maintain the Figurative and Not the Historical Meaning" — Augustine sets the two-level reading down as a rule:
Yet no one ought to suppose either that these things were written for no purpose, or that we should study only the historical truth, apart from any allegorical meanings; or, on the contrary, that they are only allegories, and that there were no such facts at all, or that, whether it be so or no, there is here no prophecy of the church.
and closes by affirming that the events both happened and signify:
… we must rather believe that there was a wise purpose in their being committed to memory and to writing, and that they did happen, and have a significance, and that this significance has a prophetic reference to the church.
The preceding chapter (15.26) had drawn the figure in full — "That the Ark Which Noah Was Ordered to Make Figures in Every Respect Christ and the Church" — so Augustine is the anchor case of allegory atop history: he reads the ark as a type of Christ and the Church because, not instead of the fact that, Noah really built it and the Flood really came.1
Even Philo, the heaviest allegorist, keeps the literal sense as the floor. The Alexandrian Jewish exegete whose method the Christian allegorists inherited insists that Moses "is a man as far removed as possible from any invention of fables, and one who thinks fit only to walk in the paths of truth itself," and, expounding the Flood's destruction of the animals, marks off "the literal statement of the holy scripture" as the base on which his moral reading is built.2 If even Philo treats the narrative as truth and not fable, the Christian writers downstream of him are not plausibly read as history-deniers.
Origen, the arch-allegorist, defends the ark as a real structure. Against Celsus — who mocked the story as a garbled copy of the Greek Deucalion flood — Origen argues in Against Celsus 4.41 for the ark's literal build and capacity (reckoning its dimensions so as to answer the ridicule), defending the Mosaic account as a real event even while he reads it figuratively elsewhere: the opposite of denying its history.3
A survey of the Genesis 6–9 commentary across the patristic record turns up the same pattern in every Father usually called an allegorist — Clement, Ambrose, and the rest read the figure on top of the event — and turns up no named writer who treats the narrative as pure allegory with the history denied.4
What holds. Both halves of the sharpened question come out for the thesis. (a) The patristic allegorists retained the history: Augustine makes the both/and a rule and condemns the figure-only reading by name of its error; Philo keeps "the literal statement" as the floor; Origen defends the ark's real construction against a pagan scoffer. "Allegorist" did not mean "denier." (b) No named ancient Christian writer is securely shown to have denied the Flood's historicity. The popular conflation of "read figuratively" with "judged unhistorical" simply does not survive contact with the texts.
What is overstated or imprecise. The one datum that cuts against a maximal reading of the thesis is, ironically, Augustine's own. In rejecting "those who maintain the figurative and not the historical meaning," he testifies that such a reading existed as a recognized category in his day — otherwise there would be nothing to reject. So it is not quite true that no one in Christian antiquity ever read the Flood as figure-only; rather, the position was live enough to be named and refuted, yet Augustine attaches no individual to it, and no other source fills in a name.1 The honest finding is therefore narrower and stronger than the slogan: not "the thought never occurred to anyone," but "no named patristic writer can be shown to have held it, and the major allegorists demonstrably did not." That is enough to defeat the "allegory = denial" inference without pretending the figure-only reading was unthinkable.
Sound. The interpretation this argument serves — that the patristic allegory of the Flood was layered atop an affirmed history rather than substituted for it, and that no named ancient Christian writer denied the Flood's historicity — holds on the primary texts. Augustine states the two-level reading as a rule and rejects both the bare-history and the figure-only errors (City of God 15.26–27); Philo and Origen, the heaviest allegorists, keep the literal event as the floor of their figures. The single correction to register is that Augustine's own refutation shows a figure-only reading existed as a category — so the precise claim is "no named denier," not "no one ever entertained it." Trust the thesis that allegory was not denial and that the historical reading was universal among named writers; flag only the over-strong form that treats the unhistorical reading as literally inconceivable in antiquity, when Augustine himself names it to condemn it.
Augustine, The City of God 15.26–27, trans. Marcus Dods (NPNF1 2), newadvent.org / ccel.org. Chapter 27 (titled "… that We Cannot Agree with Those Who Receive the Bare History, But Reject the Allegorical Interpretation, Nor with Those Who Maintain the Figurative and Not the Historical Meaning"): "no one ought to suppose either that these things were written for no purpose, or that we should study only the historical truth, apart from any allegorical meanings; or, on the contrary, that they are only allegories, and that there were no such facts at all"; and "… that they did happen, and have a significance, and that this significance has a prophetic reference to the church." Chapter 26 is titled "That the Ark Which Noah Was Ordered to Make Figures in Every Respect Christ and the Church." That Augustine bothers to reject "those who maintain the figurative and not the historical meaning" attests that a figure-only reading existed as a category in his day, though he names no one who held it. ↩↩
