Our Savior, dearly beloved, was born this day. Let us rejoice. No, there cannot rightly be room for sorrow in a place where life has been born. By casting out fear of death, life fills us with joy about the promised eternity. No one has been cut off from a share in this excitement. All share together, a single reason for joy. Our Lord, finding no one free of guilt, has come to liberate all.

Let saints exult, for victory lies within their reach.
Let sinners rejoice, for they have been called to forgiveness.
Let heathens take heart, for they have been summoned to life.

Leo the Great (400-461)
