A well-known SSPX priest's private judgment in 2010 :
I believe Benedict XVI is all the more dangerous for being genuinely benevolent towards the SSPX, because of his Hegelianism. He genuinely sees no clash, but only "continuity".
Similarly, I do believe, Bishop Fellay sees no clash between Benedict XVI and his SSPX. But Bishop Fellay's SSPX is no longer the SSPX of the Archbishop, alas.
Left to themselves, I do declare that Bishop Fellay and Benedict XVI would get on together "like a house on fire". Both are typically modern men.
Bishop Fellay shows symptoms of delusions of grandeur, and of seeking totalitarian control, but I find it difficult to believe that he will get away indefinitely with oppressing his colleagues.
Priests of the SSPX have in them, in my humble opinion, too much of that pre-Conciliar "obedience", and Bishop Fellay is exploiting that weakness to the full.
But the proverb says that "Even a worm will turn". I believe that right now several colleagues are opening their eyes, but in the lifeboat on the raging ocean their attitude is, don't rock the boat...
However, when it becomes clear just how much Bishop Fellay himself is endangering the boat, then the worm will turn.
Let's hope he's right.
