John 1:1–14
The Word became flesh
1 In the beginning was the Word: and the Word was with God: and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him: and without him was made nothing that was made.
4 In him was life: and the life was the light of men.
5 And the light shineth in darkness: and the darkness did not comprehend it.
6 There was a man sent from God, whose name was John.
7 This man came for a witness, to give testimony of the light, that all men might believe through him.
8 He was not the light, but was to give testimony of the light.
9 That was the true light, which enlighteneth every man that cometh into this world.
10 He was in the world: and the world was made by him: and the world knew him not.
11 He came unto his own: and his own received him not.
12 But as many as received him, he gave them power to be made the sons of God, to them that believe in his name.
13 Who are born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14 And the Word was made flesh and dwelt among us (and we saw his glory, the glory as it were of the only begotten of the Father), full of grace and truth.

Why this matters
John proclaims the eternal Word’s divinity and Incarnation. Mary is not named. The text supplies Christological context for the title Mother of God, which refers to the identity of her Son.
