FSSP:  Indult of the dioceses, no good.  If you hear a truth in a sentence and that sentence ends with a lie, it is a trademark of masonry.  Don't go to FSSP.

I couldn't make it past a few minutes.  

The anonymous preacher in this sermon aims to prove the proper course of obedience, by comparing St. Joan of Arc to Savonarola, the Italian friar who was a major dissenter of Alexander VI, and eventually excommunicated and executed by him.  Within the first few minutes, he says that while we can admire the bravado of Savonarola, God was clearly not 'behind' him, since he's not a saint.  On the other hand, Joan of Arc who submitted to the authorities to be executed (even though it was a great act of injustice) was sainted.

The conclusion that the mystery preacher reaches is that God is pleased when we submit to authority per se.  He is displeased when we don't.

There are several things wrong with this:

1) No one has authority to command sin.  Traditional Catholics believe the Novus Ordo program to be a false sect, and being in communion with it is tantamount to being in communion with any other non-Catholic religion.  It is heresy.  Attending their services is a danger to the faith, and no man, no matter what color his buttons, can demand this of a faithful Catholic.

2) There is the question of whether the Novus Ordo hierarchy even has authority in the first place.  Different theories exist, but suffice to say, not all traditional Catholics are satisfied that the man most would regard as the local bishop is actually the local bishop, or that the man most regard as pope is the actual pope.  If they don't have the authority in the first place, then the entire issue is a non sequitur.

This sermon shows the precise problem with the FSSP and the rest of the indult group, and that is that they ultimately view the crisis in the Church as something cosmetic.  If Fr. Anonymous regarded the Novus Ordo as illicit and scandalous, he would not be making this sermon.  As such, he regards it to be simply the 'ordinary form.'  Oh, he may (only in private, of course) tell you that there is something inherently 'better' about the Latin Mass, but he doesn't actually believe that-- because the consequences that follow from the premise require him to condemn the Novus Ordo, which he won't.

And, of course, the comparison that he uses is very poor.  Joan of Arc surrendered to a mock trial the same way that Our Lord Jesus Christ did.  She submitted to a holy and pious end, even if the means which were used upon her were insidious, just as they were in the case of Our Lord.  She did not acquiesce to a sinful demand, she let the charlatans have their day and suffered in the name of Jesus Christ.  This is pleasing to God.  Attending an ecuмenical worship service is not.  

You could use the same logic to say that God shouldn't have been displeased with Cain's sacrifice.  "I mean, c'mon, he submitted to authority!"  He did.  He offered a sacrifice.  But the nature of it was repulsive, just as the nature of what a Catholic does when submitting to the Novus Ordo is repulsive.

Here is a very informative article on Savonarola written by John Lane: http://sedevacantist.com/savonarola.html

You owe obedience to all legitimate authority unless they require that you do something that violates your conscience.
