Against Heresies

The Unity of the Story

The great Gnostic teachers of the second century argued that the God of the Old Testament was a different, inferior God from the Father of Jesus Christ — that the material world was the creation of an inferior deity, that matter itself was evil, and that salvation consisted in escaping the body through esoteric knowledge. Against this, Irenaeus insisted on the unity of Scripture and the unity of the God it reveals.

This insistence has profound implications for TLA. If Scripture is one story — if the God who creates in Genesis 1 is the same God who redeems in the New Testament, if the fall of Genesis 3 is the same fall that the incarnation of John 1 addresses — then Genesis 3:15 is not a minor footnote but the hinge of the entire narrative. Irenaeus saw this and articulated it with a clarity that the tradition has never surpassed.

What Against Heresies Reveals

Irenaeus’s great contribution to biblical interpretation is the concept of recapitulation — the idea that Christ sums up and reverses the entire human story, going over the same ground that Adam traversed but in the opposite direction. Where Adam disobeyed, Christ obeyed. Where Adam fell in a garden, Christ was obedient in a garden. Where death entered through a tree, life was restored through a tree.

This is not a minor typological observation. It is a claim about the structure of reality — about the way that God’s redemptive action is not simply the addition of something new but the healing and restoration of what was broken. The story has a shape, and Christ is its completion.

The Seed of the Woman

Genesis 3:15 is, for Irenaeus, the first announcement of the recapitulation that Christ will accomplish. The seed of the woman who crushes the serpent’s head is, in Irenaeus’s reading, the Virgin’s Son — the one who reverses the disobedience of Eve by a corresponding obedience, who defeats the serpent not by power but by faithfulness.

Irenaeus’s theological framework is the framework within which TLA operates. When TLA reads world literature as a record of the conflict between the seed of the woman and the seed of the serpent, it is reading within the interpretive tradition that Irenaeus established. His work is not background to TLA’s argument — it is its foundation.
