No they just philosophize doctrines into existance and when they think it sounds good, the pretense is that it has been "revealed." Binding and loosing does not allow the creation of new doctrine save under a very narrow scope - that of amplifying an existing doctrine. That is the way things were under the law. As we are no longer under the law, even that extent of authority is questionable. And in any event, such things had to be made in full agreement with scripture, just as any "revelation" had to be in full agreement. Thus, saying that they don't invent doesn't moot the point that the revelation isn't in line with scripture. Therefore one must question who revealed it. But that upsets people who demand to be followed no matter what they proclaim. That isn't How it works. That's how your religion is setup; but, that isn't how Christianity is setup. And therein is the beef.
