This lovely prayer by Fr. Peter John Cameron (Magnificat) serves as my daily Christmas prayer:
Oh, divine fruit of Mary's womb, may I love you in union with the holy mother of God. May my life be filled with the obedience of St. Joseph and the missionary fervor of the shepherds so that the witness of my life may shine like the star that leads the Magi to your manger. I ask all this with great confidence in your holy name, Lord Jesus, Amen.
