“I once overheard him saying to my mother that, in spite of the lack of contemporary evidence, he believed a historical Jesus had existed, a Jewish teacher of morals, of great wisdom and gentleness, a prophet like Jeremiah or Ezekiel, but that he could not for his life understand how anyone could regard this Jesus as "Son of God". He found blasphemous and repellent the conception of an omnipotent God who could passively watch His Son suffer that bitter and lingering death on the cross, a Divine "Father" with less than a human father's urge to come to his child's assistance.”
