John 17:1-3,
1 These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
Jesus was talking to his Father and called Him the only true God. This is in complete agreement with Corinthians.
1 Cor 8:6,
But to us [there is but] one God, the Father, of whom [are] all things, and we in him; and one Lord Jesus Christ, by whom [are] all things, and we by him.
Again, the Father is called the one God.
John calls Jesus the son more than 50 times and never calls him the Father.
John 1:1,
In the beginning was the Word, and the Word was with God, and the Word was God.
If we say Jesus is God then that means he is either the Father (which is totally counter to the Creeds) or he is
not the true God (John 17:3) nor the one God (1 Cor 8:6).
Many solve the problem by finding out exactly what the "word" (logos) is in John 1:1. Hint: it's not Jesus.
Please confine the discussion to these verses in John. All the other so-called proof verses don't change what John clearly said. All verses have to fit.
