Adversus Marcionem IV.1.9 and Irenaeus Adversus Haereses IV.17 - 18 (Identical Follow Up to Malachi 1.10,11)

 

Structural Element	Tertullian — Adv. Marc. IV.1.5–10	Irenaeus — Adv. Haer. IV.33.14	Irenaeus — Adv. Haer. IV.17–18 / Demonstratio
Jeremiah 31 — New Covenant	Ecce venient dies… perficiam domui Iacob et domui Iudae testamentum novum…	“God would make a new covenant… not such as that made with the fathers…”	New covenant foretold by prophets; fulfillment in Christ
Immediate transition formula	Et alibi… introduces next prophecy	“and again…” introducing Isaiah	Same prophetic chaining method
Isaiah 43 — New things prophecy	Ne rememineritis priorum… vetera transierunt… ecce facio nova…	“Remember not the things of old… behold I make new things…”	Same Isaianic renewal motif used for new covenant theology
Hermeneutical function	Creator foretold innovation → anti-Marcionite proof	New covenant predicted by Creator → continuity	Renewal comes from same God; law fulfilled not replaced by alien deity
Malachi 1:10–11 — Pure sacrifice	Non est voluntas mea in vobis… a solis ortu usque ad occasum… sacrificium mundum…	(not in IV.33 but same logic present elsewhere)	Explicitly quoted: universal pure offering replacing former sacrifices
Meaning of Malachi	New sacrifice among nations predicted by Creator	Same prophetic renewal argument	Church’s universal oblation foretold
Sequence of prophetic catena	Isaiah shortened word → Isaiah new things → Jeremiah new covenant → Malachi pure sacrifice	Jeremiah + Isaiah paired	Malachi added to same renewal framework
Follow-up philosophical reasoning	Innovation ⇒ diversity ⇒ apparent contrariety; contrariety ≠ different god	Transformation interpreted as unity of salvation history	Change of sacrificial form without change of divine identity
Polemic target	Marcion’s dualism (“difference of powers”)	Heretical rejection of Creator continuity	Same anti-dualistic aim
Conceptual core	Creator Himself predicted change	Creator announces renewal	Same Creator institutes new oblation
