Mary’s birth makes women equal to men, and makes them equal partners in the new creation, Christ and God himself.
“At first, the feminine sex was obligated to give thanks to men, because Eve, born of Adam but not conceived by a mother, was in a certain sense born of man. Mary, instead, paid off the debt of gratitude: she did not give birth by means of a man, but by herself, virginally, through the working of the Holy Spirit and the power of God.”Cyril of Jerusalem, Catecheses 12, 29; PC 33, 761 B-C.
