Sure, but it's OK to lop off the head of the Catholic Church. This is not about Jorge or his predecessors. If Jorge were going around spewing heresy on his papal plane or in interviews with Scalfari, I could hardly care less and would let the Cardinals deal with him.
You keep quibbling about the "5 Opinions" when NONE of the 5 Opinions held that the Pope could become a heretic as Pope, i.e. that he could teach error to the Church. They all discuss Pope "as private person".
More missing the forest for the trees, focusing on the "5 Opinions" (what Avrille called the a priori arguments for sedevacantism, but they're really a list of possible explanations for the how/why) and quibbling about the precise limits of infallibility. Those are both distractions from the core problem which you keep dodging by continuing to bring everyone's focus down on the trees (into arguments that we'll never resolve here).
I keep trying to point out, "Look at the forest. It's rotten." but you ignore that perspective and keep responding by saying, "No, look at this tree and that tree. I see a piece of bark here."
Yes, Ladislaus, I do understand what you are saying. I'm not focusing on the tree, I do see the woods. Archbishop Lefebvre saw the woods from afar better than anyone. However, I think you are trying to say too much, it is not in any way certain that a Pope cannot be a heretic and promote heresy through the Ordinary Magisterium.
If you read Dom Paul Nau's study, he talks about the
intention manifested by the Pope in his teaching which determines whether or not he is teaching as a private person, rather than the mode of teaching, such as a radio interview, an encyclical, a Wednesday allocution, etc. I get the same impression reading past theologians, opposing private teaching to infallible teaching. Am I wrong here? Maybe.
I don't doubt that you are right that St Robert Bellarmine was not envisaging, in his five opinions, a situation like we currently have in the Church. Let's face it, he didn't even believe that the Pope would or could fall into heresy. And yet his is only an opinion. We can't lop off the head of the Pope so easily it seems to me, the Church has never made certain these teachings, whether it is regarding the magisterium, or the heretic pope...
Nothing has substantially changed with this current Pope, I don't believe, let us continue to observe the prudence of Archbishop Lefebvre. Maybe the African Cardinals will now join ranks with Archbishop Vigano and bring the Pope to account... I shudder to imagine the consequences if such a thing happened, I think the Good Lord will wait for more opportune times following upon a chastisement to give us a truly Catholic Pope for His greater glory and the greatest salvation of souls.
