Who (SSPX, Independent or Sedevacantist) will be in a better position -- who will have formed their faithful/clergy better -- for the post-Crisis era? That is, which side will give birth to less schismatic groups?
Who will have REALLY kept the Faith whole and inviolate, including the doctrine of the Papacy? Who will be accustomed to following orders, not being a maverick, etc.?
Those who are their own personal pope will have the hardest time.
It seems to me that Sedevacantist faithful, priests, and bishops will have a hard time putting on a yoke that they have never worn. Can you imagine Fr. Cekada taking a position in a parish "somewhere" and having to follow orders from a bishop that isn't his personal friend? Having to live on $35,000 a year, which would require a huge drop in his standard of living? But independent priests everywhere would no longer be able to run the whole show. That would take some getting used to, and many would fall to the temptation of schism.
One small example: Right now, an independent priest can wear a clerical suit or a cassock -- it depends on how "faithful" or "traditional" he feels like being. But someday, a restored Catholic Church might require the cassock for every priest.
There would be dozens of things like this.
SSPX faithful, even priests and bishops, wouldn't find anything different. They will be well-equipped for life after the crisis. The priests would continue to follow orders. Dallas, TX? Yes, father. India? Yes, father.
That tells me that the SSPX has a better stance vis-a-vis the Crisis, since it allows them to fit into a "normal Catholic Church" situation with less risk of schism.
