One of my favorite Doctors of the Church, St. Augustine, wrote: “He 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.
Unspeakably wise, He is wisely speechless. Filling the universe, He lies in a manger. Ruler of the stars, He nurses at His mother’s bosom. He is both great in the nature of God and small in the form of a servant, but His greatness is not diminished by His smallness nor His smallness overwhelmed by His greatness.”
