One God. Period. No "coequals." Note the name "Jesus Christ." Jesus is a perfect Man. Christ is God. Jesus Christ is God in the flesh. Same God as the Father only revealing Himself in the Person of Jesus.
This is where you have wandered into silliness.
There has never been and never shall be a human being who was God or became God either before during or after their human existence.
God is incorporeal, he has no physical shape or material form. Jesus said that God is the source of his existence. Any being whose source is God cannot be God.
If God revealed himself in the person of Jesus Christ it was through his word that Jesus received like manna from heaven that became his own flesh, a body of teaching, given for the life of the world, a revelation about the only right way to understand and comply with the divine commands that leads to the eternal life promised for obedience that had been lost to time ever since the death of Moses..
The key is given in the first chapter of John where it clearly states that the word of God became flesh, a metaphor for teaching, in the person of Jesus Christ.
This did not make Jesus God anymore than receiving the words of God made Moses or any of the other prophets who learned from God and spoke for him God..
John 1:1, "In the beginning was the Word, and the Word was with God, and the Word was God."
John 1:14, "And the Word was made 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."
Isaiah 9:6, "For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counseller, The mighty God, The everlasting Father, The Prince of Peace."
A God Who is able to create an entire universe and all life on it can visit His creation in a vessel of His own creation. Not hard to understand.
That is simply untrue.
God is incorporeal and has no material shape or physical form. It is impossible that God would become something that he is not and what a human being could never be.
The word became flesh is simply the author establishing that flesh is a metaphor for teaching from God in words that are both spirit and life that came into the world through Jesus in what he said was his own flesh, a metaphor for the body of teaching that was from God and received in him.
and as far as 'he shall be called mighty god', being called mighty god is not the same thing as actually being God.
There never was and never shall be a human being that was God or became God either before, during or after their human existence.
The entire teaching of the torah is a testimony against the lie prevalent in the ancient world that a human being could also be a god.
