I don't particularly care what Msgr. Perl has to say. I use his words to deal with the ignorant--people like yourself who confuse the Vatican with the Godhead. You said a moment ago you could not waste time reading a lengthy post. Too bad--since the truth doesn't always come in sound bites--nor from glib comments in a papal motu proprio written out of pique. There's a history of modernist persecution of traditional Catholicism you need to know about before you charge off in all directions. In fact, the opposite of what you suppose is true: the very people you condemn are the only ones holding onto what the apostles have transmitted. Which is sad, since this used to be the primary job of popes. But JPII is too busy writing poetry--when he isn't apologizing for something or schmoozing with Buddhists.
On one hand, a pack of snarling schismatics. On the other, the Vicar of Christ on Earth (not God but definitely His Vicar on Earth). For any actual Catholic, this is not a choice. The truth is self-evident that the SSPX schism and its excommunicated leaders are to be rejected outright without further ado. Entertaining fantasies such as the possibility that schism is correct and the Church wrong is simply not available as an option to Catholics. If you are not happy with Catholicism, formalize the fact that you have gone elsewhere. Make an honest man of yourself and recognize the obvious reality that SSPX is a mere apostasy and its adherents apostates.
