Yes, this is totally different than what the SSPX says today.
No one has shown me any quotations of the Archbishop which strongly repudiate sedevacantism in the manner that SSPX priests today typically do.
Agreed.
Interesting, because the quote I supplied on the Thuc thread (for which Cupertino is eagerly awaiting my response) was cited as a series of quotes between 1979 - 1982.
And though Cupertino is predictably awaiting to receive that information so he can forward the tired old, "But his position changed at Assissi/1986," the following words are written by Bishop Williamson in his Letters to the Rector (Volume 2, p. 98) in 1990 while the Archbishop was still alive:
"Catholics are told that if they find any Society priest taking that position, he is out of line with the Society, and in fact numbers of priests have left the Society, or forced their own dismissal, because of their sedevacantism."
So much for the conversion of ABL to sedevacantism after Assissi (much less the assertion that Catholics could determine when a pope ceased to be pope and act accordingly)!
