Church supplies jurisdiction for the needs of the Faithful, including the sacraments of confession and matrimony
Well my friend who went from SSPX to FSSP told me they would not recognize her marriage as valid. Those were very bad news for her. I'm not sure what she had to do but still, it is a process.
First of all, she did not do something praiseworthy. The FSSP might be good as one first discovers Tradition, but you can't live on breast milk forever. At some point, you need to grow up and go 100% Traditional. Someone stepping DOWN to the FSSP is compromising and giving up in some way. It's just like taking the difficulty setting down in a game -- what would you think of such a player? Only the Faith isn't a game.
Well, the FSSP is one with the Novus Ordo -- you shouldn't be surprised. The Novus Ordo rejects a lot of good things, including the Mass of All Ages, the traditional Rosary, devotion to the Sacred Heart, Fasting and Abstinence, celebrating Feast Days on the weekday they fall on, First Fridays, and the list goes on.
The fact they don't recognize my marriage -- I should consider myself in good company.
If I went to join some heretical cult, I would also expect that its followers would look askance at my marriage, since it wasn't blessed by whatever Great Leader rules that particular cult.
God recognizes it, and that's all that matters to me.
