“ I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel."
This is how the Douay-Rheims explains the passage:
"15 “She shall crush”… Ipsa, the woman; so divers of the fathers read this place, conformably to the Latin: others read it ipsum, viz., the seed. The sense is the same: for it is by her seed, Jesus Christ, that the woman crushes the serpent’s head. "
So no, God had not said something different. The verse makes a lot more sense when put properly doesn’t it? He seed is Jesus, and with her acceptance, obedience and sinless life Thru her seed Jesus the serpent’s head was chrushed. She had a very important part to play in God’s plan for our salvation, and those that ignore or ridicule the mother of God are going to have a lot to answer to…do I hear an Amen from anyone?
