O God, you have caused this holy night to shine with the brightness of the true Light: Grant that we, who have known the mystery of that Light on earth, may also enjoy him perfectly in heaven; where with you and the Holy Spirit he lives and reigns, one God, in glory everlasting. Amen.
Preface of Christmas
Because you gave Jesus Christ, your only Son, to be born for us; who, by the Holy Spirit and the Virgin Mary his mother, was made truly man, yet without the stain of sin, that we might be cleansed from sin and given the right to become your children.
