And none of these stats, not the number of countries, or the # of chapels, or the # of priests gives the SSPX *one ounce more* of legitimacy compared with some independent Traditional priest saying Mass for 10 people in a hotel room.
Both operate under supplied jurisdiction, neither is canonically regular.
Fundamentally, the SSPX is in the same status as ANY independent Traditional Catholic lifeboat chapel.
But of course the SSPX has much more impressive "stats" which has only served to go RIGHT to their head, inflating their egos massively about their own perceived greatness and importance.
In the end, they got so high on their own farts they started to choose "the good of the SSPX" as a primary good, and "the good of souls" as a secondary "nice to have" goal.
Interesting tidbit -- this was ALWAYS the Achilles' Heel of the SSPX. Even in the 1980's. Yes, even when they were good, and worthy of support. My old priest (Fr. Frank Slupski) as well as Thomas A. Nelson didn't spend a lot of time bashing the SSPX (next to no time, actually) but they DID speak the truth that "sometimes, the SSPX thinks they're the Church!" and I completely understand what they meant now. It's not that the SSPX wasn't part of the Church -- because they were. But they thought they WERE the Church. As in, "Outside the SSPX there is no salvation". That was definitely in the air you breathe in many SSPX circles. This came to a head in 2012 (the rot was there, and came to fruition on a given date -- just like Vatican II) but the tendency to self-complacency was there from the 1980's. I find that interesting.
