Every. time. Anything but sedevacantism.
Bp. Pivarunas had a decent talk about supplied jurisdiction.
Fr. Hesse also had some good points on the subject, despite utilizing the "new code" of Canon law.
Fr. Tranquillo’s view of the argument for supplied jurisdiction is that there must be a Pope to provide that jurisdiction or there must be an ordinary ecclesiological structure put in place by a previous Pope until a new one is elected. Since both are missing at this time in the Sedevacantist position, no supplied jurisdiction is possible. He argues that the Church is not a “spirit” but is a material society and that while it is true that the Church provides jurisdiction when it is lacking for justified reasons nonetheless it has to be the “material” Church that provides it.
He didn’t cite any sources for his view and I am not versed well enough in ecclesiology to comment.
If anyone can shed light on this that would be nice.
P.S.
I will listen/watch both videos.
