I've seen bornacatholic's scurrilous attempt to smear the SSPX--not unlike your own. He cites the Archbishop out of context. I have posted above the entire letter. Notice how Archbishop Lefebvre encourages his bishops to remain loyal to the Holy See, despite the apostasy of those in high places in Rome. That you and he distort this by asserting a meaning the good Archbishop never intended, is a measure of how far you both will go to slander the SSPX.
The archschismatic's letter begins with the Marcel the Upstart's remarkable theory that the See of Peter is occupied by an antichrist, i.e. JP II. If you think that the text of that letter exonerates the old miscreant, you think wrong. Words have meanings.
