“Spiritus domini super me, propter quod unxit me ad evangelizandum pauperibus” (Tert. Adv. Marc. IV.14.13) || “Spiritus Dei super me, quapropter unxit me, evangelisare” (Iren. Adv. Haer. III.18–19 context)
Methodologically, IV.14 is doing exactly what Irenaeus promises for the projected anti-Marcionite book: refutation from the materials Marcion still “keeps”, i.e., from dominical sayings (here the Lukan beatitudes / woes complex) read as already prophetically pre-scripted by the Creator. Irenaeus’s programmatic notice—Marcion “secundum Lucam autem Evangelium et Epistolas Pauli decurtantes… hæc sola legitima esse dicunt … ‘Nos autem etiam ex his quæ adhuc apud eos custodiuntur, arguemus eos…’” —matches Tertullian’s repeated tactic in IV.14: he treats the beatitudes not as “new law” from an alien deity but as the Creator’s own long-foretold dispensation now “recognized” when Marcion’s Gospel is forced to cohere with the prophets and psalms.
Structurally, the chapter advances by a stable sequence that is highly compatible with an inherited anti-Marcionite dossier rather than a merely occasional Tertullianic flourish: (i) the “edictum Christi” is introduced as a definitional block (“Beati…”), (ii) each dominical saying is then anchored in a chain of scriptural testimonia (Psalms, Isaiah, etc.), and (iii) the whole is closed by a programmatic identification of Christ with Isaiah 61 (“Spiritus domini super me… ad evangelizandum pauperibus”), i.e. a “fulfillment key” that retro-reads the beatitudes as the execution of the Creator’s prophetic plan. That exact Isaian anchor is not a random prooftext: in Irenaeus the Isa 61 “unction” formula is used to explain what “Christus” means (the anointer, the anointed, the unction-Spirit), i.e. a compact anti-gnostic/anti-Marcionite doctrinal gloss that naturally serves as scaffolding for a “refutation from the Gospel” project.
Historically/polemically, IV.14’s posture corresponds to Irenaeus’s habitual anti-Marcion frame: Marcion’s “new” beatitude-ethic is treated as a theft from the Creator’s prior promises, and the Christian present (“nomen Christianorum… odium… hodie”) is made an evidentiary bridge tying prophecy to the church’s experience—precisely the sort of “ecclesial reality as confirmation of prophecy” move that pervades Irenaeus’s argumentation when he insists that the apostolic proclamation and the prophets converge in one economy rather than two gods. Even where IV.14 is not explicitly rehearsing succession lists, it is operating with the same recensio-logic: the catholic reading is the “received” coherence of prophets + dominical logoi; the Marcionite reading is an excisionary, posterior dislocation.
Most importantly for dependence, Irenaeus’s corpus preserves a strikingly adjacent conceptual nexus: in the very section where he describes Marcion’s mutilation of Luke, Irenaeus immediately cites the Lukan “woe to the rich” theme as something Marcion cannot tolerate—“Væ vobis divitibus, quia habetis consolationem vestram… Væ… qui saturati estis… qui ridetis…” etc. That sits on the same beatitudes/woes axis that dominates Tertullian IV.14, and it functions in Irenaeus as a diagnostic for Marcion’s textual and theological strategy (cutting what contradicts his “good” god). The simplest historical model is that a pre-Tertullian anti-Marcionite dossier already paired (a) the beatitudes/woes material with (b) the Creator’s preferential concern for the poor and (c) Isaiah 61 as the interpretive “key”; Tertullian’s IV.14 then looks like an expanded, rhetorically amplified version of that prior frame.
Signs of inherited exegetical scaffolding are therefore strong: the pericope is handled as a continuous scholion-chain on dominical logoi, each lemma generating a pre-fabricated testimonia cluster, with Isaiah 61 functioning as a capstone “identity proof” (Christ = the prophetic speaker’s fulfillment). That is exactly the sort of portable, harmony-compatible commentary structure that can be (and in Irenaeus already is) weaponized against Marcion “from what he still retains.”
Condensed result: IV.14 materially supports dependence upon an earlier Irenaean anti-Marcionite framework insofar as its controlling procedure—refutation from retained dominical sayings by testimonia-chains, climaxing in Isa 61 as the Christological key—coincides with Irenaeus’s announced method (“ex his… quae adhuc custodiuntur”) and with Irenaeus’s own immediate deployment of the beatitudes/woes complex as a Marcionite pressure-point.
