What factual errors are there in the article?
For starters:
the organization, all of whose priests were excommunicated in the late 1980s
Only the Bishops were excommunicated. The priests were only suspended.
Lefebvre was always on the hard right. During World War II, he supported the pro-Nazi Vichy regime, a puppet government in the part of France not occupied by the Germans. He lamented the eventual liberation of the country
His family was opposed to the Nazi regime. His father, in fact, died in a concentration camp for being a part of the French Resistance. I believe, actually, they were monarchists, not fascists.
Lefebvre later was on an advisory committee to the Second Vatican Council (1962-65), which enacted several liberalizing and modernizing reforms within the church. But the archbishop refused to sign the council’s final reports on religious liberty and the modern church, the first sign of a rebellion that would only grow in later years.
I thought, actually, he did sign the VII documents, but was opposed to what eventually came out of the council (though I realize this is subject to some debate)
Pope John Paul II responded by excommunicating Lefebvre and all SSPX priests, and declaring SSPX in formal schism with the church.
Again, only the bishops were excommunicated. Even then, whether or not they were actually excommunicated has been subject to debate.
Also in 1989, one of Lefebvre’s “bishops,” Englishman Richard Williamson
Putting “Bishops” in quotes implies that they were/are not actually Bishops. There is no question they were
validly consecrated, meaning they are, really, Bishops. The issue is whether they were
licitly consecrated.
In recent months, Pope Benedict XVI has extended an olive branch to SSPX members, inviting them to return to the church. But the sect’s leaders rejected the suggestion outright. As a result, Benedict last September approved an institute for French priests who left the movement. The pope’s move marked the effective end to efforts by the Vatican to bring the SSPX sect back into the Catholic fold.
The recent lifting of the ecommunications has proven this last paragraph wrong - if they are going to keep up the article, they should update it.
The bulk of the article accuses the SSPX of anti-semitism. The Angelus articles I will have to look up and verify, but, of course, there is the whole Williamson issue, which has been beaten to death of late.
