Your birth, O Christ our God, has shed upon the world the light of knowledge; for through it, those who worshiped the stars have learned from a star to worship you, the Sun of Justice, and to know you, the Dawn from on High. Glory to you, O Lord!

Today the Virgin gives birth to the Transcendent One; and the earth offers a cave to the Unapproachable. The angels sing his glory with the shepherds; the wise men journey with the star. The eternal God is born for us as an infant child.
