Although the state of infancy, which the majesty of the Son of God did not disdain to assume, developed with the passage of time into maturity of manhood, and although after the triumph of the passion and the resurrection all his lowly acts undertaken on our behalf belong to the past, nevertheless today’s feast of Christmas renews for us the sacred beginning of Jesus’ life, his birth from the Virgin Mary. In the very act in which we are reverencing the birth of our Savior, we are also celebrating our own new birth. For the birth of Christ is the origin of the Christian people; and the birthday of the head is also the birthday of the body.
