For as Eve was seduced by the word of an angel to flee from God, having rebelled against His Word,
so Mary by the word of an angel received the glad tidings that she would bear God by obeying His Word.
The former was seduced to disobey God and so fell, but the latter was persuaded to obey God,
so that the Virgin Mary might become the advocate of Eve.
As the human race was subjected to death through the act of a virgin, so was it saved by a virgin,
and thus the disobedience of one virgin was precisely balanced by the obedience of another.
Then indeed the sin of the first formed man was amended by the chastisement of the First Begotten,
the wisdom of the serpent was conquered by the simplicity of the dove,
and the chains were broken by which we were in bondage to death.
Irenaeus, Against Heresies
