O God, who didst vouchsafe that, as at this time, thy Word was made flesh in the womb of the Blessed Virgin Mary: grant to us thy humble servants; that we, believing her to be indeed the Mother of God, may by her intercession find favor in thy sight. Through the same Jesus Christ our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, now and for ever. Amen.
Or this:
O God who by the childbearing of a pure Virgin hast bestowed upon all mankind the rewards of everlasting life: Grant, we beseech thee; that we may know the succor of her intercession, through whom we have been found worthy to receive the author of life, even Jesus Christ thy Son our Lord, who liveth and reigneth with thee and the Holy Spirit, one God in glory everlasting. Amen.
