Does the Latin preserve a Greek account of Marcion and his scriptures, rather than merely Tertullian’s translation of Marcionite biblical texts?
1. What would distinguish the two explanations?
A Greek biblical expression proves very little about the surrounding argument’s origin. Tertullian could translate the expression himself, encounter it in a commentary, or reproduce an established Latin rendering. More significant is a combination of a particular reading, an unusual explanation of that reading, and the same theological use of the explanation in an earlier writer.
Three questions must therefore remain distinct: Does the argument depend on Greek? Does Tertullian inherit the argument? Was the immediate document he used Greek? An inherited Greek argument can reach him through a Latin translation. Conversely, Tertullian’s own bilingual learning can produce a Greek explanation without any borrowed commentary.
Scope: all five Latin books were screened across their 146 chapters, using Evans’s online text, followed by close reading of the linguistic notices and source-critical candidates below. The working segmentation contained 1,190 numbered units. This is a targeted textual audit, not a claim of exhaustive line-by-line source attribution. Editorial apparatus interspersed with the online Latin was excluded from the interpretation. The Irenaean and Valentinian comparisons were also checked against the primary passages and Riley’s study.
2. The strongest positive cases
A. V.11.9–11: a borrowed way of reading 2 Corinthians 4:4
In V.11.9–10, Tertullian counters Marcion by moving the interpretive break after “God.” The expression “of this age” is then attached to the unbelievers rather than to God. His announcement is Nos contra sic distinguendum dicimus: he proposes a different division of the sentence.
Irenaeus, Against Heresies III.7.1–2, offers the same unusual rescue and explains it through Paul’s transposed word order. This is agreement in a grammatical and theological operation, beyond agreement in the verse. It is the strongest candidate here for an inherited antiheretical explanation of a canonical passage.
The conclusion is literary mediation, plausibly Irenaean or shared with Irenaeus. It does not identify a lost book: the surviving Against Heresies already contains the argument. Nor does the construction require a Greek document on Tertullian’s desk, since the argument can be transmitted in Latin. Tertullian also adds, in V.11.11, an alternative interpretation identifying the worldly ruler with the devil; the parallel should not erase that development.
B. V.3.3–4: Galatians 2:5, a variant accompanied by its defence
Tertullian first states the negative wording about refusing submission, but then argues for the contrary historical sense: Ergo cesserunt, “therefore they yielded.” Irenaeus III.13.3 likewise knows the affirmative reading and uses it to reconcile Paul’s conduct with the Jerusalem narrative.
The diagnostic feature is the combination of the affirmative reading and its defence of apostolic agreement. A manuscript could supply the variant; it would not itself supply the apologetic interpretation. The two writers develop the defence differently, and the reading also has a wider textual history. This is substantial evidence for a shared exegetical tradition, less specific evidence for one identifiable immediate source.
C. II.9.1–7: Greek anthropology adapted to a Latin translation problem
Tertullian distinguishes the “breath” of Genesis 2:7 from divine Spirit: Greek πνοή and πνεῦμα, Latin afflatus and spiritus. He criticizes quidam de Graeco interpretantes, translators who have obscured the distinction. He then connects the distinction with 1 Corinthians 15:45 and the difference between a maker and what the maker produces.
Irenaeus V.12.2 also distinguishes breath and Spirit, relates them to the Pauline Adam contrast, and insists on the difference between something made and its maker. The theological settings differ: Irenaeus argues about vivification, Tertullian about whether the soul’s sin compromises its divine origin. Tertullian does not simply reproduce Irenaeus’s entire chain of Isaiah citations.
This looks like selective reuse of a Greek exegetical argument, with a Latin-facing translation complaint attached to it. That complaint is precisely the kind of adaptation expected when Greek theological material is rewritten for Latin readers. Dependence on Irenaeus specifically remains less secure than the existence of the shared argumentative tradition.
D. III.18.3–4: the cross inferred from the horns of the unicorn
The unusual interpretation of Deuteronomy 33:17 has a close precedent in Justin, Dialogue 91: the animal’s horns become the projecting parts of the cross, and the thrusting of the nations becomes the cross’s activity among the nations. Tertullian adds his own ridicule, including the two-horned minotaur.
This is inherited Christian interpretation of Greek scripture, beyond anything obtainable from Marcion’s Gospel or Pauline collection alone. It does not prove that Tertullian used Justin’s lost Against Marcion: Justin’s surviving Dialogue, a testimonia collection, another writer, or Tertullian’s own earlier Latin treatment could mediate it. Its value is that it reveals a developed interpretive tradition underneath the polemic.
3. Audit of the remaining significant passages
| Passage | Observation | What it can establish |
|---|---|---|
| I.1.1–2; III.1.1 | The account of successive versions and a lost earlier work. | These refer to Tertullian’s own compositional history. They are not an acknowledgement of translating a lost Greek predecessor. |
| I.13.3–4 | Greek naming and the conception of the world as ornament: κόσμος. | Greek cultural and philosophical explanation outside the canon. Too commonplace to identify a literary source. |
| I.19.2 | Marcion is placed under Antoninus; a precise interval from Christ is reported while Tertullian declines to investigate the exact year. | Possible received chronology. Historical information about Marcion has an origin beyond his biblical text, but neither that origin nor its language is identified. |
| II.20.1–4 | The Egyptians’ losses are treated as compensation for Hebrew labour. Compare Irenaeus IV.30.1–3. | Shared apologetic tradition. Tertullian expands the courtroom presentation; he does not reproduce every component of Irenaeus’s discussion. The wage argument alone cannot establish direct dependence. |
| II.24.5, 8 | Greek “evil” can denote affliction; repentance is explained through the change of mind expressed by μετάνοια. | Greek semantic argument embedded in a defence of the Creator. A candidate for inherited commentary, but also something Tertullian could construct himself. |
| II.29.1–2; IV.1.1–2 | Marcion’s Antitheses is treated as an argument organizing the separation of law and Gospel. | The work engages a noncanonical Marcionite interpretive text. Marcion’s own treatise must be distinguished from a hostile Greek account of him. Engagement does not by itself prove direct inspection. |
| III.15.4 | The Greek rhetorical category of catachresis explains borrowing an existing name. | Greek rhetorical education, not a specific source notice. This is weaker than a shared distinctive interpretation. |
| III.22.6 | The Greek Tau is localized as nostra autem T, “our T,” in cross typology. | A Greek-oriented explanation accommodated to Latin readers. Compatible with a Greek source, established Latin tradition, or Tertullian’s own explanation. |
| IV.2.3–4 | The Gospel has no named author; its relationship to Luke is presented as an inference from comparison with the church’s accounts. | A literary identification, not a direct report of a manuscript bearing Luke’s title. The commentatores here are Gospel writers; the word does not mean commentators on Marcion. |
| IV.4.3 | Marcion’s earlier Catholic faith, donation, expulsion and letter enter the argument. | A historical/documentary tradition about Marcion. A dossier is possible; Greek provenance is not specified. |
| IV.6.1–2; V.1.9 | The announced method is to refute Marcion from material he retains. | Comparable to Irenaeus’s announced project in III.12.12. A suggestive methodological continuity, but a natural polemical strategy, not an identifying fingerprint. |
| IV.8.4 | Greek “carrying” is explained as “removing” in the healing prooftext associated with Isaiah 53 and Matthew 8. | An explanation of an external prooftext, not merely translation of Marcion’s Gospel. An inherited testimonium is possible; independent Greek knowledge suffices too. |
| IV.9.15 | The charge that Marcion removed Matthew 5:17 is justified from Jesus’ conduct: Constat ergo dixisse illum, quia et fecit. | An inference from theological consistency, rather than a neutral record of collation. It could be inherited polemic; it does not itself identify a Greek source. |
| IV.11.8 | Lebanon in Song 4:8 becomes Greek λίβανος, incense; incense evokes idolatry; the bride becomes the church called from the nations. | One of the better Greek-dependent commentary candidates. The entire explanatory chain matters. Without an independent parallel, borrowing remains a hypothesis. |
| IV.14.1 | The beatitude’s poor are rendered more pointedly as beggars, with an explicit appeal to Greek πτωχοί. | A genuine notice of Greek lexical control. It cannot distinguish a biblical manuscript from a commentary containing the biblical expression. |
| IV.25.10–14 | The unknown Father saying is treated as a shared heretical prooftext. Compare Irenaeus IV.6, which actually cites Justin’s Against Marcion. | A demonstrable earlier Greek anti-Marcionite argumentative setting for this saying. This does not establish verbatim reproduction of Justin’s lost book. |
| V.1.1–4 | Tertullian explicitly performs the part of an uninstructed disciple questioning Paul’s credentials. | First-person inquiry is a rhetorical device here. It cannot be treated automatically as a record of Tertullian’s own discovery process. |
| V.4.5 | The double sense of στοιχεῖα is explained by observing that “elements” means elementary letters among Romans too. | A possible Latin accommodation of Greek exegesis. The Latin word already permits the argument, so a borrowed Greek commentary is not required. |
| V.4.8 | The two covenants are also called duae ostensiones, followed by sicut invenimus interpretatum. | An explicit appeal to a received rendering or interpretation. It may concern translation, an explanatory gloss, or another interpretation; it is not securely a notice of a Greek anti-Marcionite treatise. |
| V.17.1 | Ephesians 1:10 is explained through “recapitulating,” Greek ἀνακεφαλαιώσασθαι. | Greek lexical explanation and a concept prominent in Irenaeus. The word occurs in Paul himself, so its presence cannot identify Irenaeus as the source. |
| V.18.1–2 | Removing Latin in changes the apparent force of deo in Ephesians 3:9. | A serious constraint on a straightforward Greek-transcription model; detailed below. It is not positive proof of a Greek commentary. |
4. Comparison with Tertullian’s handling of sources elsewhere
Against the Valentinians: the best demonstrable comparison
Here the source’s survival lets us observe what remains hypothetical in much of Against Marcion. From chapter 7 onward, Tertullian follows Irenaeus’s account of Valentinian teaching, while reshaping its presentation. Chapter 5 names Irenaeus among predecessors; chapters 6 and 9 explicitly address difficulties in rendering Greek terminology.
| Passage | Observable treatment | Relevance to Against Marcion |
|---|---|---|
| Val. 6.1–2 | Tertullian explains his use of Greek names, translation glosses, and the mismatch of grammatical gender. | Greek conceptual material is deliberately accommodated to Latin readers. An explanatory Latin aside can belong to the adapter. |
| Val. 7.1–5 / Irenaeus I.1.1 | The Irenaean account is surrounded by Ennius, a Roman apartment-house joke and comic dialogue. | Roman colour and a forceful authorial voice can coexist with substantial source dependence. |
| Val. 9.2 | The treatment of Sophia as an Aeon produces the aside viderit soloecismus, acknowledging awkward gender. | Translation friction can be localized and openly managed; it need not make an entire chapter sound translated. |
| Val. 14.3 | The Iao episode is fitted with Roman cries invoking citizens and Caesar. | A Greek narrative can become immediate Latin satire. Direct ridicule of Marcion would not establish independent access to him. |
| Val. 29.1; 33–39 | Tertullian gathers dispersed material and reorganizes later doctrinal variants. | Reordered material and transitions can reflect adaptation, although neither is a source marker without a surviving comparator. |
Riley’s introduction supplies the close comparison and also discusses the unresolved relationship to the ancient Latin Irenaeus. Consequently, even this secure example distinguishes dependence on a Greek original’s contents from certainty about the immediate exemplar’s language. It would be inconsistent to ignore that distinction in reconstructing Against Marcion.
On the Soul: Greek argument, named authority, Christian revision
In De anima 6.6–7 Tertullian names Soranus’s four-book treatment, accepts his argument for the soul’s corporeality, and rejects his denial of immortality. At 8.3 he attributes to Soranus the analogy of a ship becoming heavy and motionless out of water: the soul’s departure does not show it was incorporeal. This is engagement with an argumentative discussion of a topic, not merely a collection of primary quotations.
At 25.6 the derivation of Greek ψυχή from cooling is answered by asking whether Romans and other peoples acquire souls differently because their names for the soul differ. The language shift is exposed and challenged. This is a useful comparison for how Tertullian can transmit a Greek explanation while adding his own Latin-facing criticism. Soranus’s lost work cannot now be checked continuously against the Latin; the extent and immediacy of dependence remain questions.
Against Praxeas and On the Veiling of Virgins: useful controls
Adversus Praxean 5.2–4 distinguishes λόγος as reason and as spoken word, using Latin ratio and sermo. It demonstrates how readily Tertullian’s own exposition can turn on Greek semantics. Greek glosses in Against Marcion therefore cannot be assigned to an inherited commentary simply because they are Greek.
De virginibus velandis 1.1 promises a demonstration “in Latin too.” This is conventionally understood to imply a previous Greek treatment. Since that treatment is lost, it supports bilingual authorship but supplies no observable line-by-line model of self-translation.
5. Two passages that prevent an overconfident reconstruction
V.4.8: “as we have found it interpreted”
This initially looks like an unusually explicit intermediary notice. It should not be hidden, but neither should it bear more weight than it can carry. Michael Graves and H. A. G. Houghton discuss it as evidence for a received Latin biblical rendering. Roth’s discussion of Braun and Schmid shows why the matter is disputed: the verb can concern interpretation rather than translation, and an explanatory gloss has been proposed.
The surrounding Galatians quotation is itself expanded with material resembling Ephesians 1:21 and an ecclesial formulation. Its boundaries therefore deserve careful treatment. The wording establishes reception of an interpretation or rendering more readily than it identifies either a separate commentary or a distinct Marcionite textual alteration. This passage belongs in the evidence table with its ambiguity intact.
V.18.1: Ephesians 3:9 works more readily in Latin
T. J. Lang draws attention to Tertullian’s allegation that Marcion removed the preposition. In Latin the change from in deo to deo permits the latter to be construed as an ablative, “hidden from God.” Removing Greek ἐν, however, leaves τῷ θεῷ in the dative. It does not automatically produce the same effect.
The Greek construction is awkward for Tertullian’s accusation, rather than impossible: concealment with a dative has parallels, including Wisdom 6:22. The omission of the preposition also occurs in non-Marcionite transmission. Accordingly, the passage challenges the picture of uniformly transparent reporting from a Greek Marcionite copy. It could reflect a Latin exemplar, Tertullian’s Latin recasting, or a polemical inference. It does not by itself favour a Greek hostile source over these alternatives.
Roth’s broader comparison, conversely, argues that similarities between Tertullian’s Marcionite and non-Marcionite citations often favour his own translation from Greek. That is substantial counterevidence to a simple Latin-only explanation. But translation by Tertullian would still not, by itself, identify whether the immediate Greek material consisted of a complete Marcionite codex, excerpts, or quotations within another work. That further inference requires evidence about context and quotation boundaries.
6. Assessment
The evidence supports inherited Greek-origin argumentation more securely than it supports one immediately consulted Greek anti-Marcionite exemplar. V.11 is the strongest individual parallel; V.3 and II.9 add independent examples, while III.18 supplies a close comparison with Justin’s typological interpretation. IV.11.8 is a particularly worthwhile candidate where Greek wordplay is integrated into an extended ecclesiological argument but a specific predecessor has not been identified.
The comparison with Against the Valentinians establishes the practical possibility of the proposed mechanism. Tertullian can retain a predecessor’s sequence and arguments while supplying the Roman imagery, invective, questions and explanatory transitions that make the work sound unmistakably his own. Those features cannot certify eyewitness inspection of an opponent’s canon.
The narrow claim that he works only from a Greek biblical text is therefore inadequate as an account of his argumentative resources. The stronger exclusive claim—that his entire knowledge of Marcion’s canon came from one lost Greek work—is not established. Irenaeus is a serious candidate at particular points, but the surviving Against Heresies, other Greek predecessors, common exegetical traditions, Latin intermediaries, and direct consultation can coexist in a composite explanation.
A defensible formulation for the research is: Tertullian preserves not only representations of Marcionite scripture but also earlier arguments about how such scripture should be read. His demonstrable rewriting of Irenaeus elsewhere provides a close model for this combination of inherited substance and an assertive Latin authorial voice.
