“[The Son of God] became man through a Virgin, so that the disobedience caused by the serpent might be destroyed in the same way it had begun. For Eve, who was virgin and undefiled, gave birth to disobedience and death after listening to the serpent’s words. But the Virgin Mary conceived faith and joy; for when the angel Gabriel brought her the glad tidings, that the Holy Spirit would come upon her and that the power of the Most High would overshadow her, so that the Holy One born of her would be the Son of God, she answered, “Let it be done to me according to your word” (Lk 1:38). Thus was born of her the [Child] about whom so many Scriptures speak, as we have shown. Through Him, God crushed the serpent, along with those angels and men who had become like the serpent.”Justin Martyr , Dialogue with Trypho 100: PG 6,790-12
I think each of us is called to crush the serpent. Virgin Mary submitted to God’s will and bore God. In a sense, we can work with the Holy Spirit, submit to God’s will, and we will bear Christ inside us.
