While I can understand your outrage, that's not our determination to make. The "sect" here could only be the faction arguing that the Papacy has been functionally dead since the 1950s. The Church has suffered at the hands of unworthy shepherds periodically throughout its history, but even at the worst of times no one has doubted the functional existence of the Papacy. Sedevacantism is a novelty; and it does beg the question that if they have privately determined that the Papal throne is "empty," by what metric will they determine it to be "occupied" once more? Another private judgement? Why do we even need a Papal throne at all, if anyone can make that sort of binding determination?
While there were opposing false claimants to existing true popes in the past, there was never an instance in the history of the Church a valid living pope was a formal heretic.
Roncalli called Vatican-2 and through it, he and his heretical successor Montini set up a counter church not of Christ. Even Bishop Fulton Sheen warned of that in 1948 but he thought it would be set up directly in a Communist capital, similar to what the Red Chinese did with their false "Patriotic Church". Instead when V-2 came it ironically slipped under his radar and he hopped on board.
The Papacy belongs to the Catholic Church, not to the V-2 sect which believes any falsehood of the devil - the more absurd the better.
At this point one can only pray, adhere whole and entire to the true Faith, strive against the false sect which is merely one instrument of Satan to bring about the one world religion of the Antichrist - and wait for Christ to act to vanquish the heresies and restore the Church and fill the Papacy with a true pope.
Some people in trying to be true to Christ are confused and in attempting to be loyal to Him and His Church, falsely equate it with the V-2 sect and blindly accept any atrocity that emanates from it. In their hearts they know it is wrong, but conflicted, they become obdurate and cheerlead for it in its errors even more incessantly.
At most they pine for the "good old days" of the previous heretical non-pope, when things were not quite so blatant, when their consciences would not be so screaming, and they could rest quietly in their spiritual sloth.
They NEVER though seem to pine for the True Church when both Doctrine and spiritual practices were sound.
The V-2 sect is nothing but rotten maggot meat.
