The Nativity of Our Lord: Christmas Day December 25

O God, you make us glad by the yearly festival of the birth of your
only Son Jesus Christ: Grant that we, who joyfully receive him as our
Redeemer, may with sure confidence behold him when he comes to be our
Judge; who lives and reigns with you and the Holy Spirit, one God, now
and for ever. Amen.

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.

Almighty God, you have given your only-begotten Son to take our
nature upon him, and to be born [this day] of a pure virgin: Grant that
we, who have been born again and made your children by adoption and
grace, may daily be renewed by your Holy Spirit; through our Lord Jesus
Christ, to whom with you and the same Spirit be honor and glory, now
and for ever. Amen.
