Too many are missing the main event:
There's not likely to be any accord-- at least any public accord. Bergoglio and Mueller have probably seen how incompetent Fellay and Co handled the last set of docuмents. Fellay, in his AFD, has already sold his soul, and the SSPX, down the river. Remember-- he promised to dedicate all his efforts to bring about this union--regardless of what happens. He has never, ever, publicly stood up and retracted, to the pope and to the world, the AFD.
It is far more likely that his handlers will just have a "soft" merger. The Novus Ordo pres-by-ters will attend the new seminary in Virginia for "Latin Mass " orientation and crash courses; SSPX seminarians will be invited to Novus Ordo training camps; N.O teachers will "visit" SSPX seminaries, N.O. Bishops will continue to confirm SSPX children (like in France); marriages will be "performed" with BOTH Novus Ordo Pres-by-ters and SSPX priests both officiating (as in Europe now); and such cooperation will continue until all the parties think its ripe for a seamless agreement.
They have already accepted the Vatican Council; ninety five per cent of it is okay; they have already stopped preaching against the Novus Ordo; they have already accepted the New Mass in principle. More pres-by-ters and "monsigneurs," all unordained, will continue too move into SSPX locations (like in Ridgefield Retreat House). This is all most likely in keeping with the recommendations of their marketing consultants: Make the two organizations virtually identical, just carve out for the SSPX the "high road" type of services (e.g. the High Anglican Church), and eventually take the place of the infamous "Legions of Christ" of the Marcial Maciel debacle-- who also held themselves out to "save the church for the pope!" Behind all their pomp and circuмstance-- there was no substance, just filth. When all the old timers are hammered into submission in the SSPX, there will also be nothing behind the "pomp and circuмstances."
