Nativity feast (Birth of Jesus)
In the beginning was the Word, and the Word was with God, and the Word was God ... and the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth" (John 1:1, 14)
Clearly we understand that He was born a man, "for He became flesh." He was like the earthly human but without sin dwelling among us. He was born both as God and man never denying His Divinity. The two are united without confusion between them. God has entered into earthly history as a man.
Thus with understanding we recite, "Begotten not created, of one essence with the Father, by Whom all things were made; Who for us, men, and for our salvation, came down from Heaven, and was incarnated of the Holy Spirit and became man" in the Nicene Creed.
