I have done some research on the Truth regarding the Godhead and who the God of the Bible Truly is. I have studied all the denominations of Christianity, those who deny the deity of Christ, and those who don't, those who believe in a Trinity and those who do not. After years upon years of diligent studies I have concluded:
The Deity Of Christ :
John 8:58 - Jesus{Iesous}said{epo}unto them{autos}, Verily{amen}, verily{amen}, I say{lego} unto you{humen}, Before{prin}Abraham{Abraam}was{ginomai}, I{ego}am{eimi}.
In this immediate context the Jews are not asking Jesus who He is. Rather, they are questioning (HOW OLD) He is. Jesus had made the point that Abraham had seen His (Christ's) "day." They responded by saying, "You are not yet 50 years old, and have You seen Abraham?" That is, "Abraham lived 1800 years ago, and you are not even 50. So, how is it possible for Abraham to have seen your 'day'?" The question, then, involves age--Christ's age. How long Jesus has been around. In fact, Christ shows us this by starting his statement with the Adverb "before": "before Abraham was born..." Again, Jesus here is talking about length of TIME. "Before Abraham was born, I AM." Before Abraham was born, Christ was existing and continues to exist (the very trait of God described in Exod. 3:14).
In fact, the Jews' response to this statement also shows that Jesus described Himself with a term of deity: they tried to stone Him to death for blasphemy (which would have been the case if Christ had been a mere human).John 10:30-31 specifically states this reason for them trying to stone Jesus. the Jews challenged Jesus along these lines. But, again, in the immediate context of John 8:58, the question is not about greatness, but about just how long Christ had been around...and He clearly said that He had been around even before Abraham...which is exactly what the Jews understood Jesus to be saying, too. To repeat, the question was not "Who?" (answered by "I am He"), but the question was "How long?" (answered by "I EVER EXIST", and so existed before Abraham).
John 1:1 - In{en}the beginning{arche}was{en}the Word{logos}, and{kai}the Word{logos} was{en}with{pros}God{theos}, and{kai}the Word{logos was{en}God{logos}.
Distinction of Christ from His Father:
John 6:38 - For{hoti}I came down{katabaino}from{ek}heaven{ouranos}, not{ou}to{hina} do{poieo} mine own{emos}will{thelema}, but{alla}the will{thelema}of him that sent{pempo} me{me}.
John 8:17 - {kai}It is{grapho also{de}written{grapho in{en} your{humeteros}law{nomos}, that{hoti}the testimony{marturia}of two{duo}men{anthropos}is{esti}true{alethes}.
If Jesus and the Father are the same person, then Jesus would be bearing witness of HIMSELF, therefore His testimony would not be True, and as we know that Jesus is incapable of lying, neither is any deceit found in Him.
John 5:31 - If{ean}I{ego}bear witness{martureo}of{peri}myself{emautou}, my{mou} witness{marturia}is{esti}not{ou}true{alethes}.
John 17:24 - Father{pater}, I will{thelo}that{hina}they also{kakeinos}, whom{hos}thou hast given{didomi}me{moi}, be{o}with{meta}me{emou}where{hopou} I{ego}am{eimi}; that{hina}they may behold{theoreo}my{emos} glory{doxa}, which{hos}thou hast given{didomi}me{moi}: for{hoti}thou lovedst{agapao}me{me}before{pro}the foundation{katabole}of the world{kosmos}.
If the Father became the Son at the incarnation, then then it would be in direct conflict with the above verse that teaches that the Son had shared both the Love and Glory with His Father before the foundation or creation of the Word and before the incarnation.
We find in the New Testament that Jesus is explicitly referred to as "the Son" more than 200 times and He is never even once called the "Father." The Father? is referred to as someone else who is clearly distinct from Jesus by Jesus. Furthemore it is found that Jesus referred to "the Father" or "my Father," or "your Father" in the Gospels as distinct from himself over 179 times, you will not once find any scriptures where Jesus refer to "my Son" as distinct from himself! Even furthermore in the Gospel of John alone, Jesus refers to himself as "sent by the Father," over 40 times and He never once referred to himself as the Father who had sent the Son.
On another note, Jesus did not say that He "is" the Father, but rather that He and the Father "are" one.{ego kai ho pater hen esmen} which is rendered literally as "I and the Father one we are" The verb esmen (are) is plural in the Greek, for this reason, Jesus didn?t say, "I and the Father am{eimi} one," but rather He said that, "I and the Father are{esmen}one."
Now an examination of the word "ONE" When translated the word "one"{hen} is in the neuter gender. In the greek the neuter{hen}is indicating a UNITY of essence and not an absolute identity. Think of it this way, if Jesus wanted to communicate that He Himself was the Father, then He would certainly would have used the masculine{heis} not one person, but of one essence or nature.
When Jesus said that if you see Him then you see the Father can be explained: As God, the Son in His pre-existence was always {hos on} or "who being" the prefect and "exact representation" or{charakter} of the very Person {hupostaseos} of Him{autou} and not as Him; Hebrews. 1:3. So when you see Jesus, you "see" {as the only way to and in exact representation} the invisible unseen Father.
The God-Breathed Scriptures teach that God is "ONE" {echad},{heis} in Unity and is ONE BEING that is manifested as three eternal persons.
God Bless!
