Marcion’s Antitheses is usually described as a work contrasting the Old Testament with the gospel. That description captures its central purpose, but it does not exhaust the ancient evidence. The controversy also concerns contradictions within the Creator’s commands, inconsistencies attributed to a divine character, and conflicting statements within an author’s writings. The same comparisons could establish different gods, expose an opponent’s inconsistency, or demonstrate the unity of revelation. We need to distinguish the name of a work from the individual arguments it contained and from a method other writers could adopt.
(a) Tertullian and the plurality of “antitheses”
Tertullian defines Marcion’s antitheses as contrariae oppositiones, “opposing statements” (Against Marcion I.19.4). His explanation moves from differences between scriptural statements to an alleged difference between their divine sources. The comparisons supply the evidence; the separation of the gods is the conclusion.[1]
The plural deserves attention. A count of the word forms in the Latin text of all five books gives the following result:
| Book | Plural antitheses | Singular forms | Total |
|---|---|---|---|
| I | 1 | 0 | 1 |
| II | 6 | 1 | 7 |
| III | 0 | 0 | 0 |
| IV | 14 | 4 | 18 |
| V | 0 | 0 | 0 |
| Total | 21 | 5 | 26 |
These are counts of occurrences, not counts of separate arguments or books. The singular forms are two instances of antithesis and three of antithesim. The totals agree in the Evans transcription and Oehler’s text.[2] Book V’s arguments about Paul show why word frequency and the presence of an argumentative procedure must be assessed separately. Four uses emerge:
- A named work. At IV.1.1, Tertullian describes an opus, a work, “called Antitheses.” The singular opus accommodates a plural title. This syntax is the strongest evidence for a particular written composition.
- An individual comparison. At IV.23.5, the contrast between Christ’s reception of children and the bears that attack Elisha’s mockers is called satis impudens antithesis, “a thoroughly shameless antithesis.” Here the singular identifies one argument. The accusative singular occurs again at IV.36.12–13.
- Counterarguments produced by Tertullian. At II.28.1 he announces antitheses aemulas faciam, “I shall construct rival antitheses.” At IV.24.4, his own comparisons associate Christ with the Creator. The procedure can serve the opposite theological conclusion.
- Oppositions within one creation. At II.29.4 and IV.1.10–11, Tertullian invokes the world’s opposed elements. Light and darkness do not require separate creators. Opposition can belong within an ordered whole.
Accordingly, the plural alone cannot identify a reference to Marcion’s book. Modern capitalization does not settle the question: context must distinguish the composition, its constituent comparisons, and the general argumentative procedure.[3]
“Contradiction” also translates several Latin expressions. At II.21.1, contrarietates praeceptorum means contradictions between commands: Sabbath work is prohibited, yet the ark is carried around Jericho on the Sabbath. II.22 compares the prohibition of images with the commanded bronze serpent. These objections concern the Creator’s own legislation. At IV.1.10, Tertullian describes the charge that the Creator forbids what he commands and commands what he forbids. His response repeatedly distinguishes circumstances, purposes, and stages of divine government.[4]
(b) Other contemporary writers, with the earlier Greek background
Clement supplies an essential lexical control. In Stromateis II.11.52, he quotes 1 Timothy 6:20–21, including ἀντιθέσεις τῆς ψευδωνύμου γνώσεως, “oppositions of knowledge falsely so called.” He then says that the heretics reject the letters to Timothy because this utterance condemns them. This is an explicit occurrence of antitheseis in Clement, embedded in scriptural quotation and anti-heretical argument.[5]
Book III uses a different noun. At III.3.21.2, Clement promises to examine:
τὰς ἐναντιότητας ταύτας ἃς οἵ τε φιλόσοφοι αἰνίσσονται οἵ τε περὶ Μαρκίωνα δογματίζουσιν
“These oppositions which the philosophers express enigmatically and Marcion’s followers assert as doctrine.”
The construction gives philosophers and Marcionites as the two subjects speaking about these oppositions. It does not describe a disagreement between those groups. The context concerns first principles, birth, death, embodiment, and creation. An allusion to Marcion’s book is possible, but Clement does not identify a title here.[6]
The rest of Clement clarifies the noun’s range. At IV.6.40, the knowledgeable believer understands the world’s enantiotētes, its oppositions, as a beautiful harmony of creation. At V.13.114, the word describes light and darkness. Thus “oppositions” need not mean defects in an argument or evidence for incompatible creators. Clement can affirm their place within one harmonious world—much as Tertullian does.[7]
Other passages supply the theological answer. Paedagogus I.8 argues that divine justice and goodness belong together, and that correction can express care. Stromateis III.12.83.4 says that if the same one is lawgiver and gospel-giver, οὐ μάχεταί ποτε ἑαυτῷ, “he never fights against himself.” The immediate discussion concerns Tatian and marriage. At VI.15.125.3, Clement defines the church’s interpretive rule through the concord and harmony of law and prophets with the covenant delivered at Christ’s coming. These passages address how apparently discordant teaching can proceed from one divine source.[8]
Clement also uses opposition language for conduct. Marcionites resist their Maker through abstinence from marriage (III.3.12); the Antitactae oppose commandments through contrary actions (III.4.34–37). These groups should not be collapsed into one. Clement’s vocabulary covers doctrinal opposition, practical resistance, and inconsistency, according to context.[9]
Irenaeus places self-contradiction near the center of his account. In Against Heresies I.27.2, he reports Marcion’s characterization of the Creator as warlike, unstable in purpose, and contrary to himself. I.27.4 promises a separate refutation from Marcion’s writings without naming a work called Antitheses.[10]
At IV.28.1, Irenaeus describes opponents setting the Creator’s punishments against Christ’s saving mercy. The surviving Latin calls this e contrario opponentes, “setting against in opposition.” His answer is that they suppress Christ’s judgments: both mercy and judgment belong to the same God. At IV.32.1, he reverses the accusation, arguing that abandoning the Creator produces inconsistencies in the opponents’ own account. The verbal resemblance to Tertullian is significant, but reconstructing the lost Greek wording of IV.28.1 as a reference to a book title would require an additional argument.[11]
Justin and Ptolemy demonstrate the wider problem. In Dialogue with Trypho 65, Justin refuses to conclude that one scriptural passage contradicts another; apparent conflict instead exposes a deficiency in his understanding. Ptolemy’s Letter to Flora, preserved by Epiphanius, approaches the problem differently: Mosaic permission for divorce conflicts with the original divine joining of husband and wife, so he distinguishes legislation by God, Moses, and the elders. Both writers confront scriptural discord, while assigning it different explanations.[12]
Celsus makes the challenge explicit. As quoted by Origen in Against Celsus VII.18, he contrasts Mosaic commands about wealth, dominion, and warfare with Jesus’ teaching about possessions and non-retaliation. Jesus ἀντινομοθετεῖ, “legislates in opposition.” Celsus asks which is lying, Moses or Jesus, and whether the Father forgot his commands or changed his mind. At VII.25, Origen suspects that Celsus acquired this argument from people who separated the deity of the gospel from that of the law. This supports the circulation of such polemic, without establishing Celsus’s direct access to Marcion’s book.[13]
Rhodon’s report of Apelles supplies another internal critique. Preserved in Eusebius, Church History V.13.6, it says that Apelles considered the prophecies inconsistent and self-contradictory. The disputed material can therefore be the prophetic writings themselves. This late-second-century testimony survives through a fourth-century historian.[14]
(c) Later writers
Origen distinguishes apparent contradiction from its resolution. In Against Celsus VII.20, he compares Ezekiel’s statements about good and non-good statutes with Paul’s contrasting descriptions of the law: a ministry of death in 2 Corinthians 3, yet spiritual, holy, just, and good in Romans 7. His term ἐναντιώματα encompasses the apparent oppositions. His solution distinguishes literal from spiritual meaning. The problem occurs within Ezekiel and within Paul, as well as between scriptural collections.[15]
In Commentary on John X.2–4, Origen also acknowledges chronological difficulties among the Gospels and defends their spiritual coherence. In Against Celsus VI.53, however, he warns that Celsus has mixed different controversies: some accusations he reproduces are arguments against Marcion. Identifying the speaker and the target is indispensable when collecting “contradictions.”[16]
The second part of the Acts of Archelaus provides the closest extended comparison. Diodorus’s report to Archelaus occupies chapters 44–45 in Beeson’s edition, corresponding to the letter in chapter 40 of the older English translation. It presents Mani as denying the compatibility of Moses’ law with Christ’s teaching. The Latin describes them as contrariam et inimicam, “contrary and hostile,” and calls the cited passages quae sibi viderentur esse contraria, “things which seemed to him to be contrary.” This passage does not name a book by Mani entitled Antitheses.[17]
| Issue | Comparison attributed to Mani | Relevant earlier discussion |
|---|---|---|
| Wealth | God makes rich and poor; Jesus blesses the poor and requires renunciation. | Celsus’s contrast of Mosaic prosperity and Jesus’ teaching, Against Celsus VII.18. |
| Egyptian valuables | Moses takes Egyptian silver and gold; Jesus forbids coveting a neighbor’s possessions. | Tertullian IV.24.1–2 compares Israel’s laden departure with the disciples’ unencumbered mission. The motif overlaps; the precise comparison differs. |
| Retaliation | An eye for an eye versus offering the other cheek. | Celsus and Origen, Against Celsus VII.25. |
| Sabbath | The wood-gatherer is executed; Jesus permits carrying a healed man’s bed and the disciples’ gathering grain. | Tertullian II.21 and IV.12 examine alleged conflicts in Sabbath commands and practice. |
| Death and life | The law of Moses ministers death; the new covenant ministers life, using 2 Corinthians 3. | Tertullian V.10; Origen, Against Celsus VII.20. |
The report continues with Paul on flesh and blood, rebuilding what he destroyed, circumcision, and knowledge of sin through the law. The method gathers statements and actions, interprets them as incompatible, and assigns them to opposed religious authorities. Archelaus responds by demonstrating continuity between the scriptural economies.[18]
This connection has received substantial scholarly attention. Jason BeDuhn’s 2007 study identifies eleven comparisons shared by the Acts and the material associated with Adda/Adimantus; seven occur in Diodorus’s report. He considers both transmission through Manichaean teaching and the author’s use of Marcionite or anti-Marcionite material. In a later discussion, BeDuhn argues more firmly for a Marcionite source behind Diodorus’s report, pointing to its concentration on Luke and Paul. This is a specific argument for inherited material, beyond a general resemblance between dualistic systems.[19]
The Acts is a fourth-century polemical narrative, whose complete text survives in Latin translation. Its attribution of arguments to Mani and the earlier origin of those arguments are separate historical questions. BeDuhn’s proposed source relationship deserves attention; the surviving narrative should not simply be treated as Mani’s verbatim speech or Marcion’s autograph.[20]
Other later witnesses show both directions of argument. In the Greek Dialogue of Adamantius, Moses’ outstretched hands bring victory and death, while Christ’s bring salvation; Joshua prolongs daylight for battle, while Paul forbids anger continuing until sunset. Ephrem’s Syriac Against Marcion III reverses the accusation: Christ’s abolition of earlier laws and restoration of injured bodies, he argues, undermine the claim that Christ is wholly alien to the Creator. In Latin, Jerome complains that Rufinus has manufactured Marcion’s antitheses from Jerome’s own writings (Against Rufinus I.5). The comparison there concerns inconsistency within one author.[21]
(d) Conclusions
First, Tertullian gives evidence for a named written work. IV.1.1 supplies that evidence through its description of a work called Antitheses. The grammatical plural alone cannot establish a bibliographical reference in every occurrence.
Second, “antitheses” also names a procedure. Tertullian constructs his own antitheses and applies opposition language to elements within one creation. Clement likewise understands cosmic oppositions as constituents of harmony. The theological conclusion depends on how the comparisons are interpreted.
Third, the controversy has several objects. It can concern conflicting commands within the Creator’s legislation, differences between Moses and Jesus, apparently inconsistent statements within Paul, or inconsistencies alleged against the opponents themselves. A collection of evidence must record which of these is involved.
Fourth, the Acts of Archelaus belongs within this history. Its second part preserves a closely comparable collection of arguments, and BeDuhn supplies an explicit case for Marcionite material behind the report attributed to Mani. Such overlap can illuminate the transmission and reuse of polemic. It does not by itself recover the exact wording or arrangement of Marcion’s lost work.
“Oppositions” is the broadest accurate translation; “contradictions” identifies the force assigned to them when they are alleged to be irreconcilable. The historical question is how particular writers moved from difference to incompatibility—or answered that move through context, interpretation, and the unity of divine action.
