O God, who by the fruitful virginity of Blessed Mary
Catholic
O GOD, who, by the fruitful virginity of Blessed Mary, hast given unto mankind the rewards of eternal salvation; grant, we beseech Thee, that we may feel that she intercedes for us, through whom we have been made worthy to receive the Author of life, our Lord Jesus Christ, Thy Son. Amen.
