Just stop it, moron.
Let's try this again. We know you've got this stupidity stuck in your cold dead brain, and it'll be nearly impossible to extract it.
By far the majority opinion among theologians is that MANIFEST heresy causes loss of office. Honorius was not a manifest heretic at any point during his lifetime. Nobody considered him a heretic or knew of his heresy. Consequently, he never lost papal office, since at not point while he was in possession of his office did he become a manifest heretic. If in 381 his heresy became manifest (something that's highly disputed but you lie about and claim that it's certain), Honorius no longer held the office at that time, since he had already been separated from it by death for several decades.
I'm so utterly sick of the liars everywhere even on a Traditional Catholic forum.
You also pretend that the issue is just cut and dry, certain, solemnly affirmed by the pope, etc. --- because it's necessary that it be so for your stupid-ass bullshit lying argument.
If you actually look into the matter, many pages have been spent on the question, and it is by no means as cut and dry as you claim with your lies.
St. Robert Bellarmine, along with Baronius, Pighi, and others ... believe that the insertion of Honorius' name into Third Constantinople was a later interpolation by the Greeks, and there had in fact been precedent for that prior to this scenario. Others don't believe that. But there are the later statements by Pope Leo II. But Leo II in his statements did NOT actually call out Honorius for heresy, but for his failure by omission to condemn heresy. So some theologians held that Leo's "endorsement" of III Constantinople included an amendment of the reference to Honorius as a heretic ... even among those who believe that the inclusion of his name on the list was real.
Just the summary of the debate goes on for pages ...
https://www.newadvent.org/cathen/07452b.htmBut you lie about how it's cut-and-dry, that an Ecuмenical Council said it and that Leo II solemnly endorsed it. Bullshit. Both statements are disputed, and then, of course, in the end, some recognition of heresy long after someone's dead cannot result in a loss of office during the person's lifetime. Honorius finished his life with a good reputation, without anyone accusing him of heterodoxy, much less heresy at any time.
Let's say now that someone today uncovered some letter from Pius IX where he admits to being some Masonic agent bent on destroying the Church, and so they decide to anathematize Pius IX. Let's say this letter was dated to 1848. So, what?, then ... does the Dogma of the Immaculate Conception now become an un-dogma, after the fact, after untold millions had accepted it as dogma with the certainty of faith for many decades? Does Papal Infallibility become an un-dogma now also? Does Vatican I now become an un-Ecuмenical-Council? But, then, wait. Pius IX reigned for 31 years. In that case, nearly all the Cardinals who elected the next Pope, Leo XIII, weren't even legitimate. So we've not had a Pope since 1846 either.
Ridiculous. Manifest Heresy removes from office only when it becomes manifest. Occult heresy does not remove from office. Both are "objective" heresy. Heresy that becomes manifest later cannot retroactively depose a Pope.
Next I will pull some quotations from Pope Leo II where he describes the condemnation of Honorius.
