I don't have to be a theologian to know that the SSPX position of acknowledging Bob Prevost is the pope while
at the same time being claiming to be in union with him after they have been formally excommunicated by him
IS RETARDED.
I make some distinctions regarding formal and material, etc. ... but, yeah, it's retarded, but, sadly, it's more than that. That's not Catholic and many modern (dogmatic) R&R are little more than thinly-veiled Old Catholics or else at the very least slouching dramatically toward Old Catholicism.
