Jesus is the I AM but not God since Jesus is the gate, bread of life, the Shepherd, the only way to the Father, and etc. You interpretation of John 5 is defeated by John 17:22 since God will not give His glory to another (Isaiah 42:8, 48:11).
Your explanation of Dueteronomy 6:4 is not an explanation and has no connection to John 17:3 other than Jesus' affirmation that the Father is the only true God.
The Father is complete in Himself or the Spirit could not have proceeded from the Father. So once again your rhetoric is exposed as nothing more than an attempt of advance a tradition of men.
The fact you want to pull Ephesians 4:5 out of context by ignoring vs. 6 shows just how desperate you are. Baptism is not the same thing as God or are you trying to add to your Godhead? One God and Father of all is a clear statement that does not need to be interpreted.
Your reasoning and logic (really lack of reasoning and logic) is getting sloppy Believer. The man Jesus Christ existed in God's predetermined plan, not as a divine entity and pulling words, phrases, and sections of Scripture out of context and interpreting words to show Jesus was preexistent may support a tradition but does not make the Trinity true.
What you have exposed with your posts is that you cannot rationalize away the truth that God the Father is the only true God.
The first Christians were the Lord's disciples and those who converted because of Peter's sermon in Acts 2. Now since Peter did not preach that Jesus is part of a triune God but is a man who God highly exalted we see that the earliest Christians were not Trinitarians. We know that a man canonized by the Catholic Church was not a Trinitarian and that man was Justin Martry. So we have both Biblical and historical facts that show the Trinity was not taught in the Bible or in the earliest centuries of Christianity.
