They are, in fact, priests ordained in an illicit manner, and no Catholic priest whose ministry is illicit – whether or not he is a member of the SSPX – may celebrate in a Catholic church, unless, of course, he be reconciled with the Church.
The difficulty proper to these priests, compared to Orthodox priests or Protestant pastors, is that their ministry in fact contributes – perhaps not in their intent – to divide the Catholic Church from the inside. And it is precisely regarding this point that my anxiety has grown in the course of the past few months. I was already horrified that a bishop of the SSPX had published a book repeatedly accusing Pope Benedict XVI of being heretical (Bernard Tissier de Mallerais, L’étrange théologie de Benoît XVI, Avrillé, 2010). This could nonetheless be an isolated viewpoint that did not engage the Society as such, even if coming from one of its bishops. The same applies to the famous declarations of Bp. Williamson, which was confirmed by his exclusion from the SSPX.
In the course of the past few months, the declarations of Bp. Bernard Fellay, Superior General of the SSPX, have sadly confirmed to my eyes the power of his Society to cause trouble within the Church, and to harm the reputation of the Church as seen from the outside.

The SSPX, their Orthodox sympathizers and New Catholic at Rorate Caeli, just ignore the bishop’s explanation and equate it with spitefulness because they don’t want to be held accountable for their own choices.
Bishop Fellay just said that the SSPX is willing to loose everything in order to preserve their “faith.” Bishop Morerod’s decision is consistent with Church law, which the traditionalists reject because they have chosen to follow their own conscience.
We all make choices and then reap the benefits and suffer the consequences. That is not persecution. That is life.

Bishop Fellay’s comments in regards to the history of SSPX:
“This is our history, the story of the Society, and of our founder. And this history, by dear brothers, continues. I would even say that, in comparison with this sublime reality, talking about whether or not to reach an agreement with Rome is something trivial.”
Trivial? Really?!? Wow. They have no interest in returning to the one true Church. They just want to try and make themselves seem relevant.
Thank you for this post, Father. I really wanted to believe in the SSPX, but it’s pretty obvious they will not submit to the Magesterium of the Church. Pope Benedict XVI has given theme every possible chance, and all they do is thumb their nose at him. What’s really sad is so many of the comments Rorate Caeli, praising the SSPX and condemning Bishop Morerod,
I’m sadly coming to believe that Traditionalists are just the flip side of liberals.
