Seem as though only Stubborn and a few of the other Old Catholics here really care whether +Lefebvre did or did not offer Mass una cuм Wojtyla. That's because they're replaced the rule of faith they have rejected in the Magisterium with the latest position of Archbishop Lefebvre (which could differ from year to year and even month to month). If +Lefebvre had started doing Novus Ordo clown Masses before he died, it would have zero effect on what I think.
