I watched the first 17 minutes of the video. I can't see anything wrong with what he's saying. Have any of the commenters on this thread watched the video?
He has an interesting view (starting about 16:00) of the ordinary jurisdiction of bishops of dioceses still remaining after a pope dies, so the sedevacantist idea of the Church being in an long interregnum doesn't really work, since sedevacantists say that the bishops, since Vll, don't have any authority, even though they liken the situation to an interregnum. If that makes sense. I'm not explaining it very well.
I'll watch the rest when I have time. I'm hoping that he brings up the idea that the Catholic Church is occupied by a Modernist sect, as +ABL believed, but I'm not sure he'll go there.
