The Child born today is the Savior of the world

"For a child is born to us, a son is given to us;
upon his shoulder dominion rests.
They name him Wonder-Counselor, God-Hero,
Father-Forever, Prince of Peace.  (Isaiah 9: 5)

"Father, the child born today is the Savior of the world.  He made us your children.  May He welcome us into your kingdom where He lives and reigns with you for ever and ever."  (Opening Prayer - Mass of Christmas Day)
