That's to be expected after having been poisoned by some of the false principles of R&R. For you it matters nothing what a Pope commands and teaches; you just do what want anyway. So for you this means something, when it should mean a lot to someone with a true sensus Catholicus.
This forces R&R to simply reject the Disciplinary Infallibility of the Church in principle, because the argument that it was never made mandatory has just been completely scuttled.
Well, I believe as Archbishop Lefebvre believed - that the Catholic Church is occupied by a Modernist sect. I've repeated this often enough, even if few care to hear it. Since this board is mostly sede, no one will really care about what +ABL taught anyway. Occupation by a heretical sect means that the Pope, being a modernist (A pope of the Modernist sect that occupies the Church), cannot be obeyed in matters that are Modernist in nature. We can assume that the Pope, being a Modernist, isn't going to require anything orthodox for us Catholics to adhere to.
Hence, we don't really look to obey a Modernist. That's difficult for you to comprehend, I know.
Sedevacantists and sedewhatevers don't really care about what causes the Crisis in the Church - they (and you) only seem to care about the fact that the Pope has promoted heresy, and that's it. No context required or needed. End of story. Well, that wasn't how +ABL saw it. You are free to reject +ABL, or try to turn him into a sede or sede-wanna be, as you have often done. A few of us aren't buying what you're selling.
