Adversus Marcionem IV.5 Programmatic Refutation of Marcion’s Antitheses through His Redacted Luke

Irenaeus (III, 12.12)Tertullian (IV.5)
…secundum Lucam autem Evangelium… decurtantes… “…but curtailing the Gospel according to Luke…”…id evangelium Lucae ab initio editionis suae stare… Marcionis vero… damnatum… “…that Gospel of Luke stands from its original publication… but that of Marcion stands condemned…”
…ex his, quae adhuc apud eos custodiuntur, arguemus eos… “…from those things still preserved among them we will refute them…”…Videamus quod lac a Paulo Corinthii hauserint… quid legant… quid etiam Romani… “…Let us examine what milk the Corinthians received from Paul… what the others read… what also the Romans proclaim…”
…haec sola legitima esse dicunt, quae ipsi minoraverunt… “…they say that these alone are legitimate which they themselves have reduced…”…Marcion flagitandus… quod omissis eis Lucae potius institerit… “…Marcion must be challenged… for clinging rather to Luke while omitting the others…”
…ad intercidendas conversi sunt Scripturas… “…they have turned to cutting apart the Scriptures…”…emendavit quod corruptum existimavit… “…he corrected what he thought corrupted…”
…ex his… arguere… “…to refute from those [texts]…”…dum constet haec quoque apud ecclesias fuisse… “…since it is established that these also were present among the churches…”
…quae ipsi minoraverunt… “…which they themselves have diminished…”…ubi manus illi Marcion intulit, tunc diversum et aemulum factum est apostolicis… “…where Marcion laid his hand upon it, then it became different and rival to the apostolic [texts]…”
…Scripturas… “…the Scriptures…”…temporum ordinem posteritati falsariorum praescribentem… et auctoritatem ecclesiarum traditioni apostolorum patrocinantem… “…establishing the order of times against later falsifiers… and defending the authority of the churches supporting apostolic tradition…”


Passage Unit (IV.5.x)Argument Function (inside Marcion’s Luke)Structural / Irenaean Method SignalsRedaction & Dependence Assessment
IV.5.1Establishes rule of antiquity: priority → origin → apostolicity → authenticityAntiquity as criterion of truth; apostolic succession logic; prefabricated anti-heretical axiomHIGH — methodological spine strongly aligned with Irenaean framework; reads as inherited principle rather than local argument
IV.5.2–3Appeal to apostolic churches (Corinth, Galatia, Philippi, Thessalonica, Ephesus, Rome) as custodians of authentic GospelEcclesial reception as validation; geographic chain of custody; succession-based authorityHIGH — direct structural parallel to Irenaean succession argument; institutional continuity used instead of textual analysis
IV.5.4Episcopal succession (Johannine lineage) as proof of textual integrityEpiscopate genealogy guaranteeing doctrinal continuityHIGH — classic succession logic; suggests reliance on pre-existing anti-heretical dossier
IV.5.5Expansion from Luke to fourfold Gospel under apostolic authorityHarmonizing quadriform canon grounded in apostolic churchesHIGH — strong Irenaean resonance; four-gospel framework presupposed rather than argued
IV.5.6Forensic argument from Marcion’s selective editingExposure of inconsistency within heretical editorial practiceMEDIUM-HIGH — inherited polemical trope applied with juridical framing
IV.5.7Hierarchical authority: apostles → disciples → churches; truth precedes falsificationChronological reconstruction of corruption; apostolic rule of faithHIGH — anti-heretical axiom (“truth precedes falsification”) matches established Irenaean method

Tertullian, Adv. Marc. IV.5: “si constat id verius quod prius … id ab initio quod ab apostolis … quod apud ecclesias apostolorum fuerit sacrosanctum … auctoritatem ecclesiarum traditioni apostolorum patrocinantem … veritas falsum praecedat necesse est” // Irenaeus, AH III.3.1–3: “traditionem apostolorum in toto mundo manifestatam … per successiones episcoporum … cum hac enim ecclesia propter potiorem principalitatem necesse est omnem convenire ecclesiam”; cf. AH III (programmatic statement): “secundum Lucam Evangelium et Epistolas Pauli decurtantes … ex his quae adhuc apud eos custodiuntur arguemus eos”; AH III.11.8 (fourfold Gospel established in the churches).

Methodological parallels. The chapter employs the Irenaean criterion of apostolic antiquity and ecclesial transmission as decisive proof. Tertullian’s formula—truth is earlier, earlier is apostolic, apostolic is preserved in the churches—reproduces the methodological core of AH III.3, where authenticity is established through publicly traceable succession and ecclesial continuity. The appeal to multiple Pauline churches (Corinthians, Galatians, Philippians, Thessalonians, Ephesians, Romans) mirrors Irenaeus’s survey of apostolic communities as witnesses to unbroken transmission. The argument proceeds by internal critique: Marcion’s Gospel is tested against the form of Luke preserved across apostolic churches, consistent with the Irenaean strategy of refuting heretics from the materials they retain.

Structural correspondences. The argument follows the same sequence found in Irenaeus: principle of antiquity → appeal to apostolic churches → canonical stabilization of the Gospel corpus → critique of heretical innovation. Tertullian moves from a general epistemic rule (“id verius quod prius”) to historical verification through ecclesial succession, then to canonical classification (John, Matthew, Mark, Luke) paralleling AH III.11’s establishment of the fourfold Gospel grounded in apostolic authority. The structural logic prepares for detailed Gospel exegesis by first securing the historical legitimacy of the textual tradition.

Historical polemic parallels. Marcion is framed as a later founder of “posteras … adulteras” churches, echoing Irenaeus’s insistence that heretical groups lack antiquity and therefore authority. The contrast between apostolic churches and derivative sectarian communities reflects Irenaeus’s recurring argument that chronological priority and continuous succession validate orthodoxy. Tertullian’s statement that heresy edits while corrupting the Gospel parallels Irenaeus’s description of Marcion as mutilating Luke and Paul. The appeal to episcopal succession in Johannine communities corresponds closely to Irenaeus’s use of succession lists to authenticate doctrinal continuity.

Signs of inherited exegetical scaffolding. The tightly structured chain—antiquity, apostolic origin, ecclesial transmission, canonical authority—suggests dependence on an established anti-Marcionite framework rather than spontaneous rhetorical construction. The integration of multiple apostolic witnesses and churches resembles Irenaeus’s systematic deployment of ecclesial geography as proof. The canonical classification of the four evangelists and the emphasis on shared transmission across churches align with a pre-existing schema organizing Gospel authority prior to pericope-level analysis.

Condensed assessment. The chapter strongly reinforces dependence on an earlier Irenaean anti-Marcionite framework through its explicit reliance on apostolic antiquity, episcopal succession, and the authority of apostolic churches as methodological criteria, closely mirroring the argumentative techniques and terminology of Adversus Haereses III and corresponding to the strategy envisioned in the lost “altera conscriptio.”
