The Reverend Foster had in common with almost every great religious leader of that planet two traits: he had an extremely magnetic personality ("hypnotist" was a word widely used by his detractors, along with others less mild) and, sexually, he did not fall anywhere near the human norm.  Great religious leaders on Earth were always either celibate, or the antithesis. (Great leaders, the innovators - not necessarily the major administrators and consolidators.) Foster was not celibate.
