You misunderstand what I said. I was making the point that the Pope can't invent what we must believe. It is not up to him to teach anything new whatsoever. His office gives him authority only to teach what the Church has always taught and what Catholics have always believed--in other words, what has already been handed-down by Catholic Tradition. But if he does not do this, and will not protect that tradition but teaches novelties instead--then by default it falls to others to defend the true faith. That is not something that traditional Catholics wish to do--but they are forced by default to do this in a crisis.
Spin it any way you want.
It still does not get around the fact that when the Pope teaches and writes, either you or you confreres or both, must sit down and decide whether what he is saying falls within the ambit of "tradition" or whether it is a "novelty".
It's at precisely that point that you become the Pope.
My point is that the charism of judging what is and is not in accord with Catholic tradition is not given to each and every member of the Mystical Body, though many, in their pride, think that it is.
