I can't say anything on the topic but this impressed me:
" For example, the Romans, who in 451 declared Jesus to be fully God and fully man, viewed all those Christians from Arabia as heretics. The Modalist Christians however considered the Trinity as representing three successive modes -- the Father, the Son, and the Holy Spirit. Nestorian Christians argued that Jesus had two distinct natures -- one human and the other divine. The Gnostic Christians in turn claimed that Jesus only appeared human but is in fact God. On the other end of the scale, the Arians rejected the Trinity altogether."Thats really confusing

I had no idea were so many christians.
