That's exactly what Bishop Williamson says in his latest interview I just posted!
I hope you are wrong about a SV split, but it is pretty much the history of Tradition.
There was a massive departure from Resistance to SV in the early years. Bishop Fellay was the best ever recruiting officer for the Sedes.
I watched the first 12 minutes of the new +W video, but haven't seen that addressed yet. Thanks for posting it. I'll watch the rest of it later. Interesting that he has the same thoughts about the Resistance.
I sort of hope I'm wrong about the American Resistance going SV eventually, but it's inevitable. So why fight it. Americans are gonna do what they wanna do. Always have. I don't really care anymore. Though I really get a lot out of +W's talks. And Fr. Chazal, but he's veering ever closer to SV. It takes great strength to avoid the pitfalls of SV.
This is a Resistance forum, but most of the active forum members are SV. That says a lot. Yes, Bp. Fellay is a good recruiting officer for SV, and the SV's know that there's no hope that the SSPX will ever convert to SV, so they turn to the Resistance.
