I sense this possibility is really what has Bishop Fellay's dander up.
The problem isn't even anymore the question of an official or unofficial deal.
The problem is Bishop Fellay's tyrannical grip on the SSPX, and his determined effort to shift the SSPX into the conciliar orbit.
The solution to the problem is to break that grip, to unequivocally and unashamedly repeat the old rhetoric of Archbishop Lefebvre. To free the priests to preach authentic Tradition.
Once his power is broken, once the priests are unafraid, gradually a parallel leadership can be given the real authority. Then the effort to take back control over the money and finances can begin, and finally the effort to root out masonic infiltrators can commence in earnest.
I think that we will find that all the exits have been barred and there is no escape. No one will have access to the resources to mount a defense or rollback.
And yet, all of those resources will be at hand for Bishop Fellay, Mr. Krah, and thier cohort to devastate their adversaries. Thier will also include a very sympathetic Jєωιѕн media who will try to bury the Catholics.
