So ultimately, they are NOT sedeprivationists, but dogmatic sedes. I've been saying this for years. While in THEORY, they pay lip service to privationism and distinctions, in PRACTICE, the 'una cuм' issue makes them dogmatic sedes.
By the same token, Father Chazal does the same thing on the other side, where he's so hostile to sedevacantism that he adamantly refuses to accept the idea that his position is nearly identical to that of the sedeprivationists.
I find it rather strange, on both sides.
When Father Chazal had developed his position, which I found to be rather solid, convincing, and to which I had no objections ... I was hopeful that this would create a possible bridge between the sedevacantists and the R&R types, where that type of position, similar to privationism, could resolve many if not most of the objections that each side had toward the other, and that both could agree on some variation thereof, where those who wanted to insist upon considering the V2 papal claimants to be popes, could do so in a manner where they did not attribute the destruction of the Church to the exercise of legitimate papal authority.
BUT NOTHING HAS CHANGED. Father Chazal adamantly denies that his position is similar to that of the sedeprivationists, and the sedeprivationists don't give him the of day either ... and very few RR have actually gravitated toward Father Chazal's position, but continue to cling with white knuckles to this notion that the Holy Ghost does not protect the Church and the papacy so that they cannot destroy the Church this badly (despite the fact that Archbishop Lefebvre affirmed that position).
I honestly don't get it. I'd constantly be looking for stuff we could agree on, but they seem hell-bent on continuing the dispute and ignoring all opportunities to agree on things.
