Lover of Truth,
You implied that Archbishop Lefebvre was a Sedevacantist. So, in your view, if someone is open to the idea, then this automatically makes them an Sedevacantist?
Here's just one more example that anti-sedevacantists simply don't read anything that sedevacantists write. Either that, or they are willfully blind and will not understand what is written.
Okay, I'll put the simple question to you (since Lover of Truth doesn't want to address it directly): was ABL, in your view, a Sedevacantist?
Archbishop Lefebvre died years before I even knew that tradition still existed. He had been dead more than a decade before I had even heard of sedevacantism. All that I know about the archbishop's thoughts is from his English-language writings and sermons I have read and listened to.
It is clear that Archbishop Lefebvre was conflicted on the issue. It is clear that he was open to the sedevacantist thesis but was not prepared to openly declare it, unlike Bishop Castro Meyer. The problem with Archbishop Lefebvre is that one can find quotes from him to "prove" whatever position one wants to paint him with.
Don't worry, though, I don't expect you to actually understand a thing that I've written here. I expect that you'll read this and say that I won't tell you even though I've told you exactly what "I think" (as if what I think is of any importance).
(P.S. Lover of Truth has answered your question multiple times.)
