I said it yesterday, the SSPX hierarchy has become deck chair arrangers on the Titanic. Sedevacantes? Sedevacantes are just the deck chairs. THE SHIP IS SINKING!!!!!!

The analogy doesn't fit at all as the SSPX isn't re-arranging the sedevacantists.  The ship is indeed sinking.  Sedevacantists would be more like the lifeboats.

They spend more time, effort, and energy on combatting SVism than going after the Modernists.

Yes, but also, the SSPX functioned for years by ignoring the supposed ordinary jurisdiction from the man whom they claimed to be pope and also their local diocesan ordinary. At least the sedevacantist priest recognizes that if there is a pope or a diocesan bishop, then he would have to follow his dictates and get his permission to function.

I watched the video.  The one new (from SSPX) element they introduced to the controversy of jurisdiction, is that the priest asserted that all SUPPLIED jurisdiction (which he acknowledged is universally granted in our time of crisis) still flows only from the ORDINARY jurisdiction possessed by the diocesan bishop, stemming from the Pope.  His next assertion is that no supplied jurisdiction can be granted by a Church in which no member has Ordinary jurisdiction _ that supplied jurisdiction derives singularly and necessarily from actual ordinary jurisdiction possessed by a suoerios in the hierarchy.   It sounded a lot like the home-aloner arguments to me, but I could be wrong on that front.  I know that some theologians state that supplied jurisdiction would come from Christ Himself in such an instance, but the SSPX priest believes this to be an erroneous opinion.
Does anyone have citations refuting his theory here?  His argument in that case does nothing to destroy sedevacantism, but rather leads one also into home-alonism and admitting a defected Church... yikes.
