It's quite simple, everyone.
If the Church's Magisterium and Universal Discipline could ever go so badly off the rails that Catholics must sever communion with the hierarchy in order to preserve their faith and save their souls, the Church would have defected. ...
But that's where we are at today. I don't care what you do. You can hide yourself in a corner of the local novus ordo parish and wear earplugs while you pray the Rosary and read your St. Andrew's Missal, but the atmosphere itself will poison you. I know of that which I speak. Trust me.
As for the fssp and other indult places, just as bad. Talk about mass confusion. The pews are filled with more varieties of Catholics than a Chinese take-out menu.
Keep in mind that objectively there is not a "variety" of Catholics from the perspective doctrine, from the perspective of faith, and in the Latin Rite from the perspective of worship and discipline.
We come up with the idea of a "variety" of Catholics because the Church has been usurped by apostate heretics and their followers. Once we get this we might be able to do something about it. The same thing is happening in the world. Nations no longer have sovereignty. The world and the Church is headed by the same zionist elite who want to control our money and our souls.
