Interesting. I'm heartened to see +Schneider recognizing the SV's as, for the most part, orthodox. Yet, he's naive if he thinks they're going to respond to talks from Rome when many of them have issue with the potentially-invalid Holy Orders that most of the hierarchy, including +Schneider, would have. Recall the split that occurred within even R&R once +Fellay started negotiating with Modernist Rome.
Now, if you're sedeprivationist/impoundist, then a reality of reconciliation under an orthodox Pope would be possible, and even +Sanborn said he would submit if that were the case and V2 were tossed out. But, I doubt many of the hardliner SVists would move toward Rome even if we had an orthodox Pope because of the Holy Orders issue. This includes those in the mindset of the quoted Fr. Cekada.
