Ok, let's say the Archbishop was providentially prepared by God to de-facto lead the Traditional Movement for many years, start the SSPX, etc. This much is simply a matter of history. If you read his biography, it's clear he was arranged by God to help so many Catholics into lifeboats so they could survive (keep the Faith).
The Archbishop's crowning virtue (besides charity) was PRUDENCE. He went as far as he needed to in his resistance, but not a step farther. He did nothing without justification or a good reason.
But the Archbishop died in 1991. Would he have become Sedevacantist if he had lived to 2024? We honestly don't know.
But here's the point: I (and others) adhered to the SSPX because they were the most Catholic position, blessed by God, with good fruit, not going a step further than they had to, in their resistance/opposition to Modernism and the new man-made Conciliar Church. It was the safest place to park your Faith during the Crisis in the Church, and +ABL was clearly providential, so he was a good man to follow.
But today, aside from following the same line (today it would be the Resistance, as the neo-SSPX is closer to the FSSP now than to the classic SSPX position), what obviously providential figure is there to trust or follow?
No one. There is no sedevacantist individual OR group which screams "God is here", or "this is where you should leave (wherever you are right now) and get your butt over here, because HERE is the safest/best place to keep the Faith during this Crisis in the Church."
What Sedevacantist leader, what sedevacantist group's founding, reads like a Lives of the Saints founding of the Redemptorists, Benedictines, Dominicans, Jesuits, etc.? I'm not aware of any. CMRI was founded by Schuckardt, so that one's disqualified as a modern-day Saint story.
https://en.wikipedia.org/wiki/Francis_SchuckardtAllow me to rephrase my point:I+Archbishop Lefebvre was a holy, saintly man. How God prepared him for his life's work reads like Lives of the Saints....and I would know what those sound like, because I've read probably 300 or more such books and biographies.
Let's put it this way: if +ABL's life and work makes you feel uncomfortable, or puts you on the defensive, then maybe JUST MAYBE you hitched your wagon to the wrong horse?
Again, for those who are unaware of crucial tidbits of +ABL's heroic Catholic career, you need to investigate it for the sake of truth. His holy family, his siblings, the number of vocations in the +Lefebvre household, the fact he was a prominent clergyman before Vatican II, the fact he headed up the International Group of Fathers, the ONLY resistance by the assembled bishops to full Modernism during Vatican II. And +ABL was personally trusted by the Pope with authority over French-speaking Africa. Last but not least, this extremely well-trusted Churchman was on the committee to draft the schemata that were SUPPOSED TO BE addressed at Vatican II -- the schemata that were thrown out at the outset of the Council.
And despite having a phone book full of Traditional "groups" in current year, that was not true in 1970. All you had were scattered resistant priests refusing to say the New Mass and saying the Tridentine Mass for scattered groups of Faithful here and there all over the world. But what about would-be seminarians? They can't just go off and start a chapel, and become a priest online. They came to +ABL and begged him to start a seminary. And he did.
In the end, +ABL's PRIESTLY SOCIETY was rubber-stamped by God according to anyone who has the Faith and eyes to see. He died on March 25th, which is literally the MOST PRIESTLY DAY in the whole 365-day calendar. Holy Thursday is a movable Feast. March 25th is when the Eternal High Priest became incarnate, bridging God and man, which is fundamentally Priest. He is Priest by his very being, having both Divine and human natures. I can't emphasize this enough. +ABL didn't start "another Trad group", let alone to compete with other Trad groups. He started a Priestly Society to form priests according to the pre-Vatican II ways. Offering the Tridentine Mass in various existing and to-be-created "Mass centers" came as a logical consequence of the former.
His many experiences as a missionary in Africa prepared him to defend the Tridentine Mass (having seen its power first-hand) and also the danger of priests being alone (as he witnessed in Africa, with priests joining whole villages in binge drinking). That is why he set up the system of "Priories" in the SSPX, where priests would always have a homebase with 3+ priests to recharge their spiritual batteries.
Once we have established that +ABL was an outstanding, peerless example of Divine Providence to see us through the greatest Crisis in Church history, we move on to my second point:
IIIf I'm to leave +ABL's path and position on the Crisis, I expect to follow someone AS CLEARLY INDICATED by Providence as +ABL was, or MORE so. Not less than. In my opinion, all the "great sede priests" you listed pale in comparison to the stunning endorsement by Heaven that +ABL had.
Remember, it's not what a man DOES by his own will. That's not how it works. It's what HAPPENS, especially what happens that WASN'T the will of the saint in question. That's what you have to pay attention to.
