You've missed the point entirely.
What is Archbishops Lefebvre total count? 7 Bishops in the resistance plus the 3 ones of the SSPX.
Therefore 10.
This is the fruit. A sane fruit.
The moral lesson is that Thuc's line is not where the remnant is and where the faithful should seek refuge.
Jesus picked 12 Apostles, 1 was a dud.
The Arian heresy affected a majority of the bishops of the time.
Some could look at as the +Thuc line has been attacked more than the +Lefebvre line....
Or we can just look at the Crisis as those who are with the Vatican and its Pope and those that recognize the Vatican and its Pope no longer practice Catholicism.
