Thanks for all the replies!
I'm saying in the future there may be Novus Ordo who accept vatican 2 but dissent from new teaching (think vatican 3, or fssp priests going sede) and then become sedevacantists; this will be a different breed of sedevacantist, think: SSPXV2 or SSPVV2. What joy!
Sedes and RCWP are equally schismatic to the conciliar church, as I mentioned - they both reject what the current pope (legit or not) is teaching. They are vastly unequal in other respects; sorry, actually this analogy is more SSPX vs. RCWP because the RCWP rejects that they were excommunicated for their actions as does SSPX (and yet SSPX has "partial communion", whereas RCWP does not, so again there is not a perfect analogy here). RCWP sedevacantists would have to basically say that there is no pope, to become full-fledged protestants.
I would visualize the conciliar church as the moderate position between some of these extremes.
I am not trying to "link" sedes and RCWP together; but am pointing out that in reference to the conciliar church, they have a similar canonical position. They differ in that, as I understand, sedes are true priests and if they came back to the novus ordo would only need conditional ordination and minor training (or just to go to Confession?). Womanpriests, on the other hand, never received Holy Orders and would just go to confession and become a laywoman, and then could become maybe a nun.
Novus Ordo seemed off when they would keep talking about how "we don't do that anymore". Sedevacantism seems off when you use some of the same rationale against them. "By their fruits you shall know them" - yeah? The conciliar church is still giving out a ton of charity, has lots of families, produces decent Catholics (though maybe lukewarm) to the tune of millions of followers. How about "render unto Caeser what is Caeser's", eh, rather than outright condemning recent popes? What about going through the legal system to get them tried for heresy? Ok, sure, the cardinals are all modernists, so they'll be found "not guilty".
Still, at what point can a person just break away and claim the popes aren't popes? Or, what prevents a Catholic from doing this at any point of doubt about the Roman Pontiff? These popes, if they are not true popes, have at least been good enough "wolves in sheep's clothing". While they may kiss Korans and light menorahs, they aren't outright saying that they're Satanists, which is why many still think they're true popes.
The Catholic Church is a monarchy, and even during sede vacante periods has that structure. At this point of 50 years of sede vacante, there will be no legitimate successor to fulfill Vatican 1's "perpetual successors" dogma. I thought schismatic-home-aloner.com did a great job defending sedevacantism, but they're feeneyites. "By their fruits you shall know them"? Then there is "pope" Michael I, Palmer "pope". "By their fruits you shall know them"? So, we will forget the home aloners, antipopes elected, in-fighting between sedevacantists, as testifying against sedevacantism, but we will not forget any of the sins of the conciliar church? I love elitism, but is this a kind of unacceptable speculative elitism? What about the GOOD the conciliar church is doing? OR, could be doing if more trads would fix it rather than disappear into trad circles? Sedevacantism itself is kind of a negative identity, like a-theist.
Ok, so the conciliar church has problems. Perhaps the sedes only have lots of confidence about their position though because there are few critics (or few good critics?); or are there few critics because the position is that sound? If I go ask a Novus Ordo priest what they think about sedevacantism, they might just say, "that only lasted a few days…" There is very little conciliar perception that [long-term] sedevacantists even exist. I grew up fully as a Novus Ordo till I was 24, hearing nothing of SSPX or sedes etc. Conciliar church isn't bothered by the few sedes out there; there are equally maybe as many RCWPs; quick skim of their site, they only require like 2 years of training to become a "womanpriest".
I mean, I'm just saying that all of these things require so much seriousness, and I thank everyone who's working to try to figure this mess out. People can lose jobs over their sede beliefs, by not being able to take up jobs in the diocese (experienced this) and so on, so being a sede definitely takes commitment and the responsibility to point out the faults of the conciliar church, and the womanpriests, let alone protestants, false religions, atheists, etc. Given this high burden of responsibility, I would hope that we have millions of other Catholics to work with rather than only thousands of trads!
