"Rejoice, O Highly Favored Daughter!"

"Annunciation," Master of Panzano

Today would be the feast of the Annunciation, except that the revised calendar postpones the celebration until after Easter.  Arguments against postponement here. 

Courtesy of New Advent, here are a few words from "The Catholic Encyclopedia," 1907 edition, on this great feast:

The Annunciation is the beginning of Jesus in His human nature. Through His mother He is a member of the human race. If the virginity of Mary before, during, and after the conception of her Divine Son was always considered part of the deposit of faith, this was done only on account of the historical facts and testimonials. The Incarnation of the Son of God did not in itself necessitate this exception from the laws of nature. Only reasons of expediency are given for it, chiefly, the end of the Incarnation. About to found a new generation of the children of God, The Redeemer does not arrive in the way of earthly generations: the power of the Holy Spirit enters the chaste womb of the Virgin, forming the humanity of Christ. Many holy fathers (Sts. Jerome, Cyril, Ephrem, Augustine) say that the consent of Mary was essential to the redemption. It was the will of God, St. Thomas says (Summa III:30), that the redemption of mankind should depend upon the consent of the Virgin Mary. This does not mean that God in His plans was bound by the will of a creature, and that man would not have been redeemed, if Mary had not consented. It only means that the consent of Mary was foreseen from all eternity, and therefore was received as essential into the design of God.

You are most blessed of all women, and blessed is the fruit of your womb.
