Genesis 3:13 Then the Lord God said to the woman, “What is this that you have done?” The woman said, “The serpent deceived me, and I ate.” ... 14 The Lord God said to the serpent, “Because you have done this,
cursed are you above all livestock
and above all beasts of the field;
on your belly you shall go,
and dust you shall eat
all the days of your life.
15 I will put enmity between you and the woman,
and between your offspring and her offspring;
he shall bruise your head,
and you shall bruise his heel.”
Genesis 3:13 And the Lord God said to the woman: Why hast thou done this? And she answered: The serpent deceived me, and I did eat.
14 And the Lord God said to the serpent: Because thou hast done this thing, thou art cursed among all cattle, and the beasts of the earth: upon thy breast shalt thou go, and earth shalt thou eat all the days of thy life.
15 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. God is speaking to Eve and the serpeant. The seed of Eve is Mary. The enmity spoken of first is between Eve and her seed, and satan and his seed. THEN God gives the more specific prophecy that one of Eve's seed offspring, Mary will bear a son Who will bruise satan's head.
Let's look at the way the Hebrew Torah relates this:
Genesis 3:13 And Hashem Elohim said unto the isha, What is this that thou hast done? And the isha said, The Nachash beguiled me, and I did eat.
14 And Hashem Elohim said unto the Nachash, Because thou hast done this, thou art arur (cursed) above kol habehemah, and above every beast of the sadeh; upon thy gakhon (belly) shalt thou go, and aphar shalt thou eat all the days of thy life;
15 And I will put eivah (enmity,personal hostility [see Ezekiel 35:5]) between thee and HaIsha (see HaAlmah, Yeshayah 7:14), and between thy zera and her Zera; it shall bruise thy rosh, and thou shalt crush his akev (heel).
I would say the catholic version is a purposeful deception, to focus the action on Mary, ignoring that Mary is the seed of Eve, and implying Mary is empowered somehow by Her child, her seed crushing satan's head. The text refers 'her seed' as a descendant of EVE. That descendant came through Mary. BUT Jesus was not a 'seed of Mary', unless catholics now want to tell us that a gamete from Mary was used to make the zygotic Jesus!
Even Mary???
