this man really struggled with the issue of christians blindly following the bible. he seems to want rational thinkers to respect christian philosophy, but he seems to understand that only a heretic will ponder a moral issue and then dissent from what the bible commands, so he is really in a pickle as evidenced by the rhetoric that begins at 4:20 in this video.
he also doesnt seem to support any case for where morals come from. obviously he thinks they come from god, but he didnt address why anyone should believe that.
