I suspect that a good number of members on CI are still attached to sspx. So readers will hear little of the truth about that fallen organization on this site. Confiteor deo is a refreshing exception in her recent post. Normally we'll hear little here of substance on any topic related to sspx. The fact is that growing numbers of priests in the Society are revealed to have practiced a perverted lifestyle over at least 35 years. And their predations are routinely covered up by the leadership, to this very day. If sspx really wanted to do justice, their leaders would confess publicly to the sex crimes of its priests. They would return the deeds of all chapel properties throughout the world to their original and rightful owners. They would put their financial affairs in order, shut down all business and investment enterprises in which they are involved, and dissolve the apostolate altogether. But that will not happen.
I am "guilty" of attending SSPX masses, but I have seen a lot of bad things. It seems to me that there is a serious psychological problem with most of the SSPX priests. I have not know that many, but judging from the ones I know (about 8 I would guess), I would say that the "SSPX mentality", or "corporate culture" is very problematic. They seem to see the faithful as a nuisance, and that they are really generous to provide you with the sacraments, as if it was not their duty.
I would say that this is a social problem. Their minds are so focused, so isolated in their own organization, that they cannot really understand how other people live their lives. They seem to have no empathy.
Abp. Lefebvre organized the SSPX like any other missionary congregation, as far as I understand, but it seems clears to me that this model doesn't work in the terrible crisis of the Church, because no religious congregation was ever this isolated in the Church's history.
They answer to no one. Even after the nefarious secret dealings with Rome, they still function quite independently. I believe that this created a kind of bubble that they live in. That's why nobody can ask questions. Whoever raises his voice is treated like a troublemaker. The priests fear trouble. They fear upsetting their superior, because they know that they can be expelled very fast if they disagree about something. They have seem it before. If you don't agree with the mandatory mentality, you are seem as an outsider, and you'll surely be out very quickly.
That is also why they feel entitled to protect bad and criminal priests. They answer to no one. The superior is always right. His is the voice of God.
