Feast of St. Irenaeus

Today is the feast day of St. Irenaeus, 2nd century defender of the early Catholic faith. I am often fond of citing one of my favorite readings from his work "Against Heresies", Book III, Ch. 22 which portrays Mary as the New Eve:

In accordance with this design, Mary the Virgin is found obedient, saying, "Behold the handmaid of the Lord; be it unto me according to thy word." But Eve was disobedient; for she did not obey when as yet she was a virgin. And even as she, having indeed a husband, Adam, but being nevertheless as yet a virgin (for in Paradise "they were both naked, and were not ashamed," inasmuch as they, having been created a short time previously, had no understanding of the procreation of children: for it was necessary that they should first come to adult age, and then multiply from that time onward), having become disobedient, was made the cause of death, both to herself and to the entire human race; so also did Mary, having a man betrothed [to her], and being nevertheless a virgin, by yielding obedience, become the cause of salvation, both to herself and the whole human race. And on this account does the law term a woman betrothed to a man, the wife of him who had betrothed her, although she was as yet a virgin; thus indicating the back-reference from Mary to Eve, because what is joined together could not otherwise be put asunder than by inversion of the process by which these bonds of union had arisen; so that the former ties be cancelled by the latter, that the latter may set the former again at liberty...

And thus also it was that the knot of Eve's disobedience was loosed by the obedience of Mary. For what the virgin Eve had bound fast through unbelief, this did the virgin Mary set free through faith.

While Eve was made the cause of death to the entire human race, Mary became the cause of salvation to the whole human race. Through her obedience to God, she freely and willfully bore the Savior of the world in her womb.
