So much for the conversion of ABL to sedevacantism after Assissi (much less the assertion that Catholics could determine when a pope ceased to be pope and act accordingly)!
It does appear that way. However, I don't see why somebody can't recognize the unorthodoxy of the pope, conclude he couldn't possibly be representing the Church, and realize there are a very limited number of real actions one can actually take. Then realize these actions are the same ones almost everybody (who notices the unorthodoxy) takes.
Now, in light of the protracted and contentious debate I have been having with Cupertino, what I have to say may surprise you.
I have never been a dogmatic anti- sedevacantist.
From time to time, I even wonder if it could be true.
My whole position, which has probably been lost amongst the heated rhetoric, and which I believe was also ABLs position, is that sedevacantist might be possible, but is too uncertain to take a dogmatic stand on.
In other worde, you could say we give the benefit of the doubt to the post-conciliar popes.
Yes, ABL did say things at various times when Rome did something particular egregious that would tend to traject in the sede direction, but he never made it his position, and in fact became more active in suppressing them as time went by.
And certainly he never advocated that people could discern and judge individually, and act accordingly. That they could not is the primary reason he never did himself.
