The Future: A repressive religious dictatorship rules a stratified, opiated society in America where no man may advance himself except through religious hypocrisy.
Suddenly a young priest, sincere in his religion, finds himself the power of spontaneious healing, a power of overwhelming political import in a society whose medical care is reserved for citizens of high status.
He is rescued by the underground after fleeing the police, and while trying to develop and control his unique talent, he inadvertently encounters a survivor of a decadent alien civilization and finds his power increased enormously.
It took a while for the stories to come together, and the title really doesn't suit the book well. It's got cultural extremes of both too much sex and too little sex, and the unlocking of human potential trope.
