Pope John Paul has just died as we film this program. Now there is urgent speculation about choosing a successor who will modernize the papacy. "Why can't women become priests?", many ask. Why teach against birth control when most Catholics practice it anyway? Why can't priests marry and have a family like everyone else? At the same time, the protestants are all divided about abortion. Many major protestant denominations are moving toward ordaining homosexuals as ministers. Who decides what is right and what is wrong? Who decides what sin really is?
