If this is true, and it smells like Bp Fellay's usual actions, then the good Bishop Williamson could finally be expelled from the Neo-SSPX "very, very" soon.
For sure the Neo-SSPX can't join New-Rome as long as Bishop Williamson is a formal member. Because the good shepherd always throws a monkey wrench into the works of the New-Roman and Menzingen modernists. They must be "very, very" angry on him. :-)
During the last years the brave bishop resisted Menzingen's desperate efforts to eliminate his blessed opus Dinoscopus. I think it's likely that continues his important Eleison Comments, because he and many others know well that it's the last voice of a true Catholic Bishop hearable all over the world in five important world languages. Read weekly by (hundreds of?) thousands readers worldwide. He also knows that the days we can use the Internet are numbered, so... why stop it now!
So, if the good Bishop should be expelled from the Neo-SSPX, what would he do? I think there's a possibility that he would join the US resistance around Fathers Pfeiffer, Chazal and the others. Even if the Bishop stayed in England (which would be great for us Europeans :-) , he could join them logistically. Which would attract more priests from the world to join the True-SSPX, and well, finally they would get a true bishop.
Well, we will see. God bless Bishop Williamson and all the other truth-loving clerics like Fr. Chazal, Fr. J. Pfeiffer, Fr. Ringrose, Fr. Weinzierl, Fr. Meramo, and many more.
