Sedevacantism is only secondarily about the pope at all (whether interior dispositions or heretical actions). It's about what we believe about the Catholic Church.
R&R: Church is capable of teaching grave error, of leading souls to hell, and of promulgating a Rite of Mass (Church's publish worship) that undermines faith and offends God.
SV: Church can't do that.
Interesting how sedes view this.
From R&R point of view:
R&R: The pope is capable of teaching grave error,
of leading souls to hell, and of promulgating a Rite of Mass (Church's publish worship) that undermines faith and offends God.
SV: The pope can't do that.
People that are led to hell are always led of their own free will, not one of them are forced to follow anyone to hell - or to heaven for that matter. It is by Divine design that the direction we choose to take is ultimately the result of our own free will.
You may need to contemplate that for a bit, I don't know, but use yourself and even all trads as an example of this truth. You really should cease from exempting any blame at all on all the people who of their own free will choose to be led to hell - and I think that all of your syllogisms would be a lot more interesting if you remembered this, as well as remembering that the pope is not The Church, when making them.
Conservative Novus Ordo agree with SV, while liberal Novus Ordo agree with R&R on this MAJOR (of the entire crisis).
MAJOR: Catholic Church cannot do such evil (SVs + Conservative NO) - rejected by R&R and Liberal NO
MINOR: Conciliar Church did such evils. (SVs + R&R) -- rejected by Conservative NO + Liberal NO
CONCLUSION: Conciliar Church is not the Catholic Church (SVs)
*Liberal NOs like the reforms, but might think, for example, that the Church did evil in the past
R&R:
MAJOR: Catholic Church cannot do such evil. (all)
MINOR: Conciliar Church can and do such evils. (R&R and SV)
CONCLUSION: Conciliar Church is not the Catholic Church. (R&R and SV)
All NOers (if they ever heard of it), reject the idea of a conciliar church that's not Catholic. For that matter, there are many R&R and SV who also reject the idea of a conciliar church that's not Catholic.
