Jesus is the One through whom all things have been made and on Christmas, Who has been made in the midst of all things. He is the Revealer of His Father and the Creator of His mother, the Son of God through His Father without a mother and the Son of Man through His mother without a father.

He is great in the eternal day of the angels but small in the time-conditioned day of men. He is the Word of God before all time and the Word made Flesh in the fullness of time. Maker of the sun, He is made under the sun.

Disposer of all ages in the bosom of His Father, He consecrates Christmas Day in the womb of His mother. In Him, He remains while from her He goes forth. Creator of the heavens and the earth, He is born on earth under the heavens. 

Augustine of Hippo, 354-430
