To reply to what you said about Trinitarians, I believe in the Trinity. For one, in Genesis God says, "Let us make man in our own image". Us! Who was he talking about; God the Father, God he Son, and God the Holy Spirit! Jesus said that he was gonna send us a Comforter. Who was he talking about; The Holy Spirit! And how could God have sent his son if he didn't already exist? God isn't schizo, but there is a tri-union.
