Can you envision a world in which the Catholic Church still held the kind of sway over all matters, not only religious but civil and political, that it did in the Fifteenth Century? (Several good sci-fi/alternative history books have been written with that premise, of course.) Outside of the realm of imaginative fiction, however, it's difficult to believe that such a situation could exist in modern times. I understand what it is that you're suggesting; I guess what I'm asking, then, is don't you think the schisms, the divisions, the multiplication of sects and denominations and cults was inevitable? After all, there were many breakaway sects before Luther's time which defied the Church's dogmatic pronouncements; is there any reason to think that things would have turned out differently without him?
