@neologist,
I agree--I am NOT a Trinitarian neither were the apostles. The early church knew nothing about Trinitarianism. This was the making of Constantine and the Catholic Church.
God indeed was manifested in the flesh. See John the first chapter.
He was seen of angles, received up into glory--Who? The scriptures say God. Who was Jesus? According to the scripture below HE IS GOD! Not a second person in a triune god head nor was he an angel nor was he Jehovah JR.
I Timothy 3:16
16And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
