Sounds like we have an idiot troll on the forum ^^^
You're new to this forum, troll, but I have called out Archbishop Lefebvre's error on EENS numerous times. This doesn't mean he was anything but confused and mistaken in good faith. You've done nothing but troll against Archbishop Lefebvre since you got here, first starting multiple threads questioning the validity of his Holy Orders and then multiple threads calling him a heretic. I'll give you some benefit of the doubt that you're too much of an idiot to understand the difference between pertinacious / formal heresy and material heresy (good faith error). +Lefebvre made his statement believing it to be the teaching of the Church, and therefore adhered to it due to material error. This undermining of EENS has gone on so long that even otherwise orthodox and conservative Catholics were hoodwinked into believing it.
Now, as said before, get lost.
