Gordias, Centurion, Martyr, Lincinius -- 3 Jan [307-324]
The First Sunday after Christmas
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.
