The flaw in your reasoning is that Rome is the one in schism (with Catholicism). SSPX is “as Rome”, without some of the baggage, as it was for over a thousand years. Rome is the one that needs to return to untarnished (by modernism and ecumenism) Catholicism.
“Rome” is in schism? In other words the Pope is in schism. Sounds pretty sedevacantist to me. I love these broad brush statements that Lefebvrists use to brush away Catholic doctrines like Papal primacy, the authentic magisterium of Popes and Councils approved by the Pope, interpreted in continuity with Tradition, which doctrines actually predate Vatican II, which did not create a new religion, unlike both the Lefebvrists and the liberal Modernists hold. Thank God for Popes John Paul II and Benedict who have actually been working constructive slowly but surely to steer the Barque of Peter away from the shoals of the so called “Spirit of Vatican II”.
“Rome is the one that needs to return to untarnished (by modernism and ecumenism) Catholicism.”
I so agree with your statement!! Yet I do recognize the pope as valid as I am not a sedevacantist - yet it IS Rome that went off course - not SSPX. This very issue troubles me very much because I HATE the Novus Ordo and its failed New Agey weakened doctrine/dreadful liturgies - etc.!! This state of confusion in the Church troubles me deeply - I have no doubt whatsoever that the smoke of Satan did enter with Vatican II.
Thoughts? I am in no man’s land and I don’t like it and I actually think we are all there although many don’t notice it.
