Notice also that the Father did not become the Father and the Son did not become the Son until the incarnation:

Hebrews 1:5 (NIV)
5 For to which of the angels did God ever say, “You are my Son; today I have become your Father”? Or again, “I will be his Father, and he will be my Son”?


We have a preincarnate ***le for the Son before he became the Son:

John 1:1 (NIV)
1 In the beginning was the Word, and the Word was with God, and the Word was God.


John 1:14 (NIV)
14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.


The Father is mentioned in this verse but from the perspective of post incarnation. There is no other ***le or name given to the Father (other than the general "God" or "Lord / YHVH" which applies to all three persons / individuals of the Godhead.
