Both Clemens Maria and Sbyvl speak of "missed opportunities".
God doesn't miss anything. You still talk as if the Crisis had been meant to end after 10 years, but it's gone on for 45 thanks to Archbishop Lefebvre.
Don't you think God is in control? If God wanted it to end 10 years ago, trust me, we wouldn't be having this conversation right now. Maybe it's part of the chastisement.
I suppose it could be argued that Archbishop Lefebvre played a negative but necessary role like Judas. Still, I would disagree with that. Judas committed a very clear-cut and evil mortal sin: betraying his Master. Did the Archbishop really do something like that? He kept a very Catholic mindset during the whole crisis, and up till recently, his organization the SSPX was doing the most to help souls and solve the Crisis. I just don't see the bad fruits there. On the contrary, there were countless good fruits and that is why they were so popular.
You can't use the Novus Ordo is even more popular argument to slam the SSPX. That alone says nothing. So just because it's more popular means it's worse? So...eating food is objectively wrong, and those who eat ash and dirt are the true remnant? Sometimes the majority is right!
Just because the SSPX failed eventually (under +Fellay) doesn't mean it was rotten from the beginning, as many suggest.
The lights went out, and we are in crisis. Trying to analyze and criticize each individual extension of a person's arm to feel his way around in the dark, each bump into a piece of furniture, each step taken in the wrong direction -- kind of pointless. The real problem is the fact that the lights went out! I'm sure all the men in that room were trying to find their way honestly.
Why would cross your mind the image of Judas when talking about Dom Lefebvre?
I know that you didn't mean to do a strict analogy, still it's very shocking for me to read this.
