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.

OR

ALMIGHTY God, who hast given us thy only. begotten Son to take our nature upon him, and as at this time to be born of a pure virgin; Grant that we being regenerate, and made thy children by adoption and grace, may daily be renewed by thy Holy Spirit; through the same our Lord Jesus Christ, who liveth and reigneth with thee and the same Spirit ever, one God, world without end. Amen.
