Saved by a Virgin

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,
but the latter was persuaded to obey God,
so that the Virgin Mary might become the
advocate of the virgin Eve. As the human
race was subjected to death through [the
act of] a virgin, so it was saved by a virgin.
