And Mary said: “My soul proclaims the greatness of the Lord; my spirit rejoices in God my Savior . . . From this day all generations will call me blessed: the Almighty has done great things for me, and holy is his Name ” (Lk 1:39-56)

The Visitation to Elizabeth help us to understand the great plan of Salvation: God comes to rescue the poor and the lowly. And as Elizabeth says, “Who am I, that the mother of my Lord should come to me?” The church rightly calls Mary, “Theotokos” (God-bearer), in Latin “Mater Dei” (Mother of God). The Western Church prays: “Pray for us O holy Mother of God, that we may be made worthy of the promises of Christ.” The Eastern Church prays: “Remembering our most holy, pure, blessed, and glorious Lady, the Theotokos and ever virgin Mary, with all the saints, let us commit ourselves and one another and our whole life to Christ our God.”
