The Only New Testament Reference to Genesis 3:15

There's a debate going on at the Boar's Head Tavern about who is it who is being referred to in Genesis 3:15:

And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.

Who will bruise the serpent's head? Jesus or Mary? (You can find posts debating this question here, here, here, etc.)

The funny thing is (along the lines of this post), is that according to the New Testament, it is neither Jesus nor Mary who bruises the serpent's head, but the congregation of the saints (through whom God the Father works). As Paul wrote to the Roman congregation:

For your obedience is come abroad unto all men. I am glad therefore on your behalf: but yet I would have you wise unto that which is good, and simple concerning evil. And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen.


Has this passage ever received theologization?
