Yeti: Thank you for suggesting the term sedeagnostic. I had not come across that term and I am glad to learn it. I don't believe there is a word, sedeapocryphist, so truthfully, I thought I was bringing in a new word to describe someone who holds that the seat of Peter is occupied by one of doubtful authenticity. A key part of this is who is and who is not in a position to say with any certainty? Never-the-less, here's my thinking. Is it possible to identify a heretic? I think it is. If it is, then even one occupying the seat of Peter, unwilling to recant of heretical statements, could be aptly identified as a heretic. So, the next question to contemplate is whether one unwilling to recant of heresy can be aptly seen as a Catholic? I do not think someone can be a willful heretic and a Catholic. And if being a heretic and a Catholic are not compatible, the final question is how could it be possible for a heretic, who is not a Catholic, to occupy the seat of Peter and be authentically recognized as the Pope? Anyway, that's my logic. I believe that God can use a heretic to bring the faithful closer to Him, or to test His flock's faith, and perhaps that is what He is doing. I also believe we are called to use common sense, logic, and reasoning to direct our thinking, our faith, and our actions.
