Paragraph 2676. This twofold movement of prayer to Mary has found a privileged expression in the Ave Maria: (722, 490, 435, 146)

Hail Mary [or Rejoice, Mary]: the greeting of the angel Gabriel opens this prayer. It is God himself who, through his angel as intermediary, greets Mary. Our prayer dares to take up this greeting to Mary with the regard God had for the lowliness of his humble servant and to exult in the joy he finds in her.

Full of grace, the Lord is with thee: These two phrases of the angel's greeting shed light on one another. Mary is full of grace because the Lord is with her. The grace with which she is filled is the presence of him who is the source of all grace. "Rejoice... O Daughter of Jerusalem... the Lord your God is in your midst." Mary, in whom the Lord himself has just made his dwelling, is the daughter of Zion in person, the ark of the covenant, the place where the glory of the Lord dwells. She is "the dwelling of God... with men." Full of grace, Mary is wholly given over to him who has come to dwell in her and whom she is about to give to the world.

Blessed art thou among women and blessed is the fruit of thy womb, Jesus. After the angel's greeting, we make Elizabeth's greeting our own. "Filled with the Holy Spirit," Elizabeth is the first in the long succession of generations who have called Mary "blessed." "Blessed is she who believed...." Mary is "blessed among women" because she believed in the fulfillment of the Lord's word. Abraham, because of his faith, became a blessing for all the nations of the earth. Mary, because of her faith, became the mother of believers, through whom all nations of the earth receive him who is God's own blessing: Jesus, the "fruit of thy womb."

Paragraph 2853. Victory over the "prince of this world" was won once for all at the Hour when Jesus freely gave himself up to death to give us his life. This is the judgment of this world, and the prince of this world is "cast out." "He pursued the woman" but had no hold on her: the new Eve, "full of grace" of the Holy Spirit, is preserved from sin and the corruption of death (the Immaculate Conception and the Assumption of the Most Holy Mother of God, Mary, ever virgin). "Then the dragon was angry with the woman, and went off to make war on the rest of her offspring." Therefore the Spirit and the Church pray: "Come, Lord Jesus," since his coming will deliver us from the Evil One. (677, 490, 972)

Paragraph 2001. The preparation of man for the reception of grace is already a work of grace. This latter is needed to arouse and sustain our collaboration in justification through faith, and in sanctification through charity. God brings to completion in us what he has begun, "since he who completes his work by cooperating with our will began by working so that we might will it:" (490)

Indeed we also work, but we are only collaborating with God who works, for his mercy has gone before us. It has gone before us so that we may be healed, and follows us so that once healed, we may be given life; it goes before us so that we may be called, and follows us so that we may be glorified; it goes before us so that we may live devoutly, and follows us so that we may always live with God: for without him we can do nothing.
