"Of course Jesus was a theist, but that is the least interesting thing about him. He was a theist because, in his time, everybody was. Atheism was not an option, even for so radical a thinker as Jesus. What was interesting and remarkable about Jesus was not the obvious fact that he believed in the God of his Jewish religion, but that he rebelled against many aspects of Yahweh's vengeful nastiness. At least in the teachings that are attributed to him, he publicly advocated niceness and was one of the first to do so. To those steeped in the Sharia-like cruelties of Leviticus and Deuteronomy; to those brought up to fear the vindictive, Ayatollah-like God of Abraham and Isaac, a charismatic young preacher who advocated generous forgiveness must have seemed radical to the point of subversion. No wonder they nailed him."
