ABL was a sede-doubtist ... just like myself.
Is that how +ABL described himself? I don't recall that he did.
In +ABL's last book, in 1986 (I think it was his last), which was called "Open Letter to Confused Catholics," he wrote this in the last chapter on page 175:
"I have not ceased repeating that if anyone separates himself from the Pope, it will not be I. The question comes down to this: the power of the Pope within that Church is supreme, but not absolute and limitless, because it is subordinate to the Divine authority which is expressed in Tradition."
+ABL wrote that he had not ceased to repeat that he will not separate himself from the Pope. Is that what sede-doubtists' believe? Though, of course, sede-doubtism is probably a recently made-up term, and may not have been in existence when +ABL was alive.
