Jesus was revered as the Messiah, a favored son of God and at least semi-divine from the earliest days of Christianity. Constantine did strong arm the bishops at Nicaea into rejecting Arianism in favor of "consubstantiality" that conceives of Jesus as co-equal with the Father. I guess my quibble is that it wasn't an abruptly demarcated transformation, but more an official sanction of a certain theological tradition.

I agree with you that Jesus didn't consider himself to be God. I think he believed himself to be the Messiah.
