I really am posing this to everyone, Catholic or not. When a person claims that God told them to start a new denomination, and they do, is it naturally a part of their “revelation” that God can only or has only guided them and has never reveiled anything to anyone else? Let us say for arguements sake that a man sudenly shows up on TV with some sort of new form of Chrisitanty, radically different than any that exist today. Why should we beleive that God spoke to him about this and has ignored all other Christians up to this point? Further, why should we accept his claims when he says that we are to only follow him?
I hope this post makes sense. I am not talking about those who break away from or reform a denomination. I am asking about those who present radically new ideas about God. By whose authority?
