There's something fundamental you're missing Raoul, but I haven't been able to clearly lay it out yet. Part of it is "I don't know where to begin".
What it is, is that Raoul is like a slow progression, like the rest of us. At first, remember, I don't think he would even attend a CMRI chapel. Fortunately, there must have been some sort of Grace from our Lord that he was infused with to send him somewhere to receive the Sacraments, much like the rest of us have been so graciously helped undeservedly by our Blessed Lord and His Mother.
I think Raoul finally found a 'community', if you will, that he can belong to, yet still cling onto some of his inaccurate views; but they're tolerated, and I'm sure sometimes shared, there. Isn't it interesting that he has no formal theological training, yet can declare, at will and with an air of authority, who is and isn't heretical? Isn't it interesting that any actual traditional "Theologian", with formal training, has never declared this of the SSPX? Sorry, your sede-priest isn't a Theologian. Isn't it interesting that Raoul, can claim he 'knows' all the arguments of the SSPX (and I'm not saying they're perfect), yet I doubt, if you ask him, he's had more than a few actual conversations with a priest from there.
Everything he gathers is probably from his sede-forums or french sede friends. He once said something to the extent of, "Sorry to break it to you (sspx-ers), but in the sede conversations are a SSPX bash." Wow. Ya, SSPX-ers do nothing but admire CMRI on a regular basis.
The point is, and it always goes back to this, is the post Matt once made on everyone trying their best in tradition and that unless someone has recieved some sort of divine revelation on what exactly is right and what to do, we need to keep trying to find truth. Unfortunately I couldn't find it (the post he made) right now, but if I do, I will post the link to it here.
