Eve sorrowed, but Mary exulted; Eve carried weeping in her womb, but Mary carried joy, for Eve brought forth a sinner, but Mary innocence itself. The mother of our race brought punishment into the world, but the Mother of our Lord brought salvation into the world. Eve was the source of sin, Mary the source of merit. Eve by killing was a hindrance, Mary by giving life was a help. Eve wounded, Mary healed. Obedience takes the place of disobedience, faith makes up for faithlessness.
Mary may now play on her instruments, the Mother strike the cymbals with swift fingers. The joyful choruses may sound out and songs alternate with sweet harmonies. Hear, then, how she sings, she who leads our chorus. For she say, 'My soul magnifies the Lord, and my spirit rejoices in God my Savior; because He has regarded the lowliness of His handmaid; for, behold, henceforth all generations shall call me blessed; because He who is mighty has done great things for me.' And so the miraculous new birth takes away the cause of our increasing burden of sin, and Mary's song puts an end to the weeping of Eve." (St. Augustine of Hippo, Sermon 18, On the Saints)
