The idea
The same Hebrew verb, shuph, describes both blows in Genesis 3:15: the seed crushes the serpent's head and the serpent strikes his heel. 'The mysterious thing about the battle is that both sides appear to lose.' Pitre's image: crushing a snake's head is the safe way to kill it, but 'if you try to step on its head, you take a fairly big risk of being struck on the heel before killing it.' The next chapter of Genesis reads the oracle spiritually: sin is a beast 'lurking at the door' waiting to strike Eve's son Cain, who must 'master' it.
Key verses
- Genesis 3:15 — 'it shall bruise thy head, and thou shalt bruise his heel' — one verb.
- Genesis 4:7 — sin 'crouching at the door' — the Bible's own gloss on the war.
- John 12:31 — the serpent's head crushed at the cross, where the seed is also struck.
The connection
| Old Testament root | New Testament fulfilment | |
|---|---|---|
| The seed crushes the serpent's head and is struck in the heel | → | Christ defeats Satan at the cross by dying |
The oracle already contains the shape of the passion: victory and wound in one act. And Genesis itself, in the story of Cain, shows that the 'serpent' to be mastered is sin, not a reptile.
