January 6 – From the Tome of St. Leo
For, as we must often be saying, he is one and the same, truly Son of God, and truly Son of Man. God, inasmuch as “all things were made by him, and without him nothing was made.” Man, inasmuch as he was “made of a woman, made under the law.” The nativity of the flesh is a manifestation of human nature; the Virgin’s child-bearing is an indication of Divine power. The infancy of the Babe is exhibited by the humiliation of swaddling clothes: the greatness of the Highest is declared by the voices of angels. He whom Herod impiously designs to slay is like humanity in its beginnings; but he whom the Magi rejoice to adore on their knees is Lord of all. — Council of Chalcedon (A.D. 451), Session II
