The basis of the difficulties, as it has been in so many of the Church’s scandals and human tragedies, is the institution’s moronic insistence on a celibate clergy. Nine hundred years is a sufficient data set to conclude that the experiment, which has no basis in the gospels unless you reverse engineer them beyond all recognition, has been a terrible failure on every level. If Papa Francesco wants to leave a mark on the Church, and on the people in it, that will bring him the praise of ages, he at least could make the requirement optional. Otherwise, the Church is going to be working poor Rezendes to death.
