Hodie Christus Natus Est

When Augustus reigned alone upon earth, the many kingdoms of men came to end: and when Thou wast made man of the pure Virgin, the many gods of idolatry were destroyed. The cities of the world passed under one single rule; and the nations came to believe in one sovereign Godhead. The peoples were enrolled by the decree of Caesar; and we, the faithful, were enrolled in the Name of the Godhead, when Thou, our God, wast made man. Great is Thy mercy: glory to Thee.
