Incarnation

He it is by whom all things were made, and who was made one of all things; who is the revealer of the Father, the creator of the Mother; the Son of God by the Father without a mother, the Son of man by the Mother without a father; the Word who is God before all time, the Word made flesh at a fitting time, the maker of the sun, made under the sun; ordering all the ages from the bosom of the Father, hallowing a day of today from the womb of the Mother; remaining in the former, coming forth from the latter; author of the heaven and the earth, sprung under the heaven out of the earth; unutterably wise, in His wisdom a babe without utterance; filling the world, lying in a manger.

Augustine
