I do believe that the Scriptures teach that the blessed mother is the new Eve. This is the earliest of blessed mothers titles in the Scriptures. This was the first prophesy when God said to the serpent:
(Gen 3:15 DRB) I will put enmities between thee and the woman, and thy seed and her seed: she shall cursh thy head, and thou shalt lie in wait for her heel.
This is the first prophecy that in the beginning was Eve and though she was disobedient she will be victorious over the evil one (CCC489)
This passage in Genesis is called the Protoevangelium or first Gospel announcing the Messiah and Redeemer of a battle between the Woman and the serpent. It is clear that the Woman announced in the Protoevangelium is the Mother of Christ and the new Eve, restoring mankind to their hope of eternal life through her yes to bear Christ. In doing so she reverses Eve’s disobedience with her own obedience in cooperation with Christ, the New Adam, who reverses Adam’s disobedience with His obedience “unto death on the cross”……
(1Co 15:21 DRB) For by a man came death: and by a man the resurrection of the dead.
(1Co 15:22 DRB) And as in Adam all die, so also in Christ all shall be made alive.
(1Co 15:45 DRB) The first man Adam was made into a living soul; the last Adam into a quickening spirit.
(Phi 2:8 DRB) He humbled himself, becoming obedient unto death, even to the death of the cross.
It cannot be denied and is recognized by the Church, “Death through Eve, life through the blessed mother”. She is the New Eve.
