Dogmatic sedeism should be rejected, just like the 'dogmatic R&Rism' of the Arville Dominicans.
Both R&R is a theory and so is Sedeism. That is the conclusion. That is the truth.
Any side which wavers from theory to dogmatism, is wrong. The current crisis has. no. concrete. solution. Why is this so difficult for Trad clerics to grasp?
Every flavor of Tradism, if it is valid, and if it rejects V2/new mass = acceptable to God.
Outside of this, and God is not pleased. It's that simple.
Unfortunately and since at least 2013, many traditional priests and bishops who are no longer part of the NeoSSPX have fallen into error and now a false mentality of “whatever nourishes your faith” which means the New Mass is not absolutely rejected in all cases.
This of course trickles down to a tradecuмenism and a blending of the Conciliar SSPX with the SSPX of old, truth annd error, and really any other compromised group so long as it “nourishes your faith” and is “valid”
