O Almighty God, who out of the mouths of babes and sucklings hast ordained strength, and madest infants to glorify thee by their deaths: Mortify and kill all vices in us, and so strengthen us by thy grace, that by the innocency of our lives, and constancy of our faith, even unto death, we may glorify thy holy Name; through Jesus Christ our Lord. Amen.
Then shall follow the Collect of the Nativity.
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.
