The Conception of the Theotokos + December 9
Anna besought the Lord in fervent prayer for a child. The voice of the angel proclaimed to her: God has granted you the desire of your prayer. Do not weep, for you shall be a fruitful vine, bearing the wondrous branch of the Virgin who will bring forth in the flesh the blossom Christ, Who grants great mercy to the world.
Today the great mystery of all eternity, whose depths angels and men cannot perceive, appears in the barren womb of Anna. Mary, the Maiden of God, is prepared to be the dwelling place of the eternal King Who will renew human nature. Let us entreat her with a pure heart and say: Intercede for us with your Son and God that our souls may be saved.
