I remember reading a quote that unmistakably demonstrated that +Lefebvre believed one can be saved outside Holy Mother Church. Perhaps he was just parroting the error/s of his age, but reality is reality, no?
Frankly, it would be more beneficial for everyone if +Vigano asked for prayers for +Lefebvre's soul, rather than acting like it is a given he is already in Heaven.
Yes, I believe he was simply regurgitating the errors he was taught himself by various seminary professors whom he considered otherwise Traditional / conservative / trustworthy. This speaks to how deeply this error had insinuated itself into the minds of Catholics everywhere, long before Vatican II. Most Traditional Catholics have succuмbed to this error. +Lefebvre was no theologian, was never trained as one, never pretended to be one; he was a missionary, an extension of a parish priest.
There's probably a bit of Novus Ordo thinking there by assuming +Lefebvre is already in Heaven, but, if after 33 years, he's not in Heaven by now, given his personal virtue and holiness (by all outward appearances), then I can pretty much give up hope of ever making it myself.
