The Trinity, in principle, as I understand it, is supposed to make God more intimate and by extension to demonstrate the myriad of ways that God can be understood. I agree that God can be understood in myriad of ways; however the concept of the trinity I believe is un-scriptural, and contrary to reason. I am a proud, unapologetic Christian in the Universalist and Unitarian traditions. Jesus being a devoted Jew, and an itinerant Rabbi was a human prophet who constantly subordinated himself to God, and was attuned to God's presence and voice. He constantly recited the Shema- O Hear O Israel the Eternal our God is one and only one (Deuteronomy 6:49) Later as Jesus was being crucified at the hands of the Romans for preaching God's all inclusive love, and radical hospitality he questioned God in the famous words of Psalm 22, "My God, My God- why have you forsaken me?" In Luke 22:42, Jesus as he is ready to be executed is going through a crisis of faith and asks his God, "Father, if you are willing, remove this cup from me; yet, not my will but yours be done" When Jesus is praying in the garden, then why is it is necessary, if Jesus is God? I believe in worship that one worships and prays to God, and to God alone not the messenger. If one is finite as Jesus is, then one cannot also be infinite. If one is infinite as God, then God cannot be finite. In John 4:24, it states that God is spirit, and those who worship God must worship in spirit and truth" With God being spirit, spirit doesn't have a body, and spirit therefore cannot be divided. A Unitarian Godhead makes more sense to me as it brings Christianity back into harmony with Judaism, that rather than saying that there is a God of y tradition, and a God of x tradition, that by affirming God's oneness then all of us are beloved children of a singular unitary God. Further, Unitarian theology allows us to follow to the religion of Jesus (his teachings, and example) as opposed to the religion about Jesus (creeds, dogmas made up about him) finally, if God is one it also says that the human family is one, our Earth is one. In regard to the verses that seem to defend the Trinity, when it comes to John 10:30 of Jesus claim that I and the Father are one. He is not talking about being the same substance of God of but instead he refers to spiritual oneness of being attuned to God's voice. Next comes John 8:5-8 where Jesus is said to "tell people the truth" that before Abraham was born, "I am". I am is the name of God, and nowhere in this passage is it referring to Jesus he is pointing back to God. In John 14: 7, which says that if you have seen Jesus, you have seen his Father? This verse tells us that by Jesus actions and his words you are given a glimpse of God.
I still use the language of Father, Son, and Holy Spirit or in the modern speak Creator, Redeemer and Sustainer. The traditional language can be interpreted from a Unitarian theology. Father is the Eternal God, Jesus is a son of God in that we are all children of God, and the Holy Spirit is the power of God's love manifest in the universe or the divine spark within.
