Seems to me, Amos, that Jesus' theism was pretty much conventional for his time...he believe in the same God as the others. It was his ideas about proper human moral conduct that were quite unusual:

forgiveness
turning the other cheek
nonviolence
treating everyone the same...even if they weren't Jews
driving moneylenders out of the temple

It was those kind of radical ideas that set him apart from the Jewish authorities of his time, not his notions of theism. They were afraid he would upset the applecart, as it were.

He spoke on a level they were not prepared to deal with, and they chose to take some of his symbolic statements in a literal fashion...as fundamentalists always seem to do. I guess that subtlety escapes them. ;-)
