Nativity in the flesh of our Lord God and Savior Jesus Christ

Gospel of John 1:1 "In the beginning was the Word, and the Word was with God, and the Word was God ...  He came to his own home, and his own people received him not. But to all who received him, who believed in his name, he gave power to become children of God; who were born, not of blood nor of the will of the flesh nor of the will of man, but of God. And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only Son from the Father."

St. Augustine in a Christmas Sermon: "Our Lord Jesus Christ, the Son of Man as well as the Son of God, born of the Father without a Mother, before all days. By his birth from a Mother without a Father, he consecrated this day. In his divine birth he was invisible; in his human birth, visible; in both births, awe-inspiring."

Kontakion of Advent: “The Virgin cometh today to the cave to give birth ineffably to bring forth the Word eternal. Therefore, rejoice, O Earth at the message with the angels and shepherds give glory to Him who shall appear by his own will as a young child, he who is from eternity God”
