Obviously, your conclusion does not follow.
You in fact set yourself up as pope and declare a new doctrine of the Church - the doctrine of sedevacantism.
You're completely missing the point. It was OP who made his argument against SVism rest upon the premise that Honorius had become a pertinacious heretic. SkidRow was merely refuting that particular argument, not using it to further any particular contrary position.
As Skid points out, AL created this poll because he thought he had some slam-dunk argument against sedevacantism, and not just against sedevacantism, but promoting the one Opinion that Bellarmine dealt with in his treatment of the "5 Opinions", namely, that a Pope cannot lose his office short of death or resignation. He stated precisely that "conclusion" early on in this thread.
MAJOR: Honorius was a pertinacious manifest heretic.
MINOR: Honorius remained Pope his entire life and did not lose the papal office.
CONCLUSION: Pertinacious Manifest Heresy does not cause loss of office.
THIS is what the whole point of this stupid thread was.
We pointed out early on that the MAJOR is disputed, and therefore, due to the logical principle of
peiorem partem sequitur conclusio (logical weakest link, where the conclusion can be no more certain than the weakest of its premises), the CONCLUSION is equally disputed.
Instead of dealing with the fact that the MAJOR is disputed, he kept wasting everyone's time by just repeating the assertion over and over again, applying the
ad nauseam technique.
"Catholic writers dispute that Honorius ever became a pertinacious manifest heretic."
To which he would just say ...
"Third Council of Constantinople declared him a heretic. Pope Leo II approved the Council." like the parrot, "baaaah, baaaah, baaah"
This whole stupid argument went on interminably, and apparently this dead horse is still being beaten here ... when intellectual honesty would have put an end to it within the first couple pages.
Despite his brilliant reasoning, which he tries to pretend has the support of an Ecuмenical Council and Pope Leo II ... by far the two most widely held opinions about a heretic pope are those of Bellarmine (
ipso facto deposed) and Cajetan (must be "ministerially" deposed), but evidently none of these theologians saw the light of OP's unassailable argument, or else, they would have dropped that opinion. Bellarmine, for instance, argued that 3 Constantinople didn't condemn Honorius but that some Greeks interpolated his name into the Council texts. That's a minority opinion, but ... no matter how you slice it, OP's argument fails, but he remains clutching it with his cold dead brain no matter what evidence has been adduced against it.
