In 2009, Pope Benedict has told us plainly what happens every time a traditional society makes a purely practical agreement, with modernist Rome:

I myself saw, in the years after 1988, how the return of communities which had been separated from Rome changed their interior attitudes; I saw how returning to the bigger and broader Church enabled them to move beyond one-sided positions and broke down rigidity so that positive energies could emerge for the whole.

The pope’s observation was right! Look what happened to these groups who made a practical deal with modernist Rome:

• The Good Shepherd Institute – For five years, it had the right to exclusively use the Traditional Mass and had “true doctrinal freedom, with respect to the doctrines and authority of the Church”. Then Rome took these concessions away.  Sources: http://www.remnantnewspaper.com/Archives/2009-0228-interview-good-shepherd.htm and http://z10.invisionfree.com/Ignis_Ardens/ar/t9206.htm; French version: http://www.la-croix.com/Religion/Urbi-Orbi/France/Rome-demande-a-l-institut-du-Bon-Pasteur-de-mieux-integrer-Vatican-II-_NP_-2012-04-17-795546.

• The Society of St. John Marie Vianney, in Campos, Brazil – In 2002, the Dominican “theologian of the papal household”, Fr. Georges Cottier, said that Rome would give Campos time to weaken, before imposing the new mass. Bishop Rifan now concelebrates the new mass and defends this practice as “normal, correct and good” and required by “doctrinal principles”.  Sources: http://gloria.tv/?media=166615; http://rorate-caeli.blogspot.com/2011/08/note-on-concelebration-of-holy-mass-in.html; Si Si No No, September 2002, at: http://www.sspxasia.com/Documents/SiSiNoNo/2002_September/Ambiguous_Accord.htm.

• Dom Gerard and the Benedictine monks of Le Barroux– The new mass is now said at the formerly traditionalist bastion of Le Barroux and the monastery now defends the false religious liberty it used to attack before 1988.  Sources: Si Si No No, September 2002, at http://www.sspxasia.com/Documents/SiSiNoNo/2002_September/Ambiguous_Accord.htm and http://www.ecclesiadei.nl/docs/fiuv03_neri.html

• Institute of Christ the King, Sovereign Priest– This indult group teaches that all of Vatican II’s teachings, including those concerning religious liberty and ecumenism, are in harmony with the traditional teaching of the Catholic Church. Institute priests concelebrate the new mass.  Sources: http://www.michnews.com/cgi-bin/artman/exec/view.cgi/275/12362; SSPX Canadian District Magazine, Convictions, Issue 16, March 2009, p.26, quoting Institute founder and Prior General, Msgr. Gilles Wach, from Fideliter #187.

• The Society of St. Peter –After eleven years, the Society of St. Peter’s “exclusive use” of the traditional Mass ended and Rome also imposed its own choice of a (more liberal) superior general and seminary rectors.  Sources: http://www.catholicapologetics.info/apologetics/defense/negotiations.htm. http://latinmassmagazine.com/articles/articles_1999_FA_Woods.html

• Redemptorists Of Papa Stronsay – Within four months after making a deal with Rome, these Redemptorists reversed their position that the SSPX was within the Catholic Church. They began using the pope’s ecumenical Good Friday prayer for the Jews. Rome placed them under their local modernist bishop. They send their seminarians to the Society of St. Peter seminary, to receive an indult-type formation.    Sources: http://papastronsay.blogspot.com/2008_03_01_archive.html. http://www.zenit.org/article-23205?l=english. http://papastronsay.blogspot.com/2008/02/solemn-prayers-of-good-friday.html. http://www.catholicherald.co.uk/news/2012/08/15/traditionalist-group-granted-formal-status-within-the-church-after-a-four-year-wait/. http://www.facebook.com/media/set/?set=a.269653879753163.81399.161482623903623&type=3.

We Know Rome’s Plan for the SSPX, when Rome “recognizes” the SSPX (with or without a signed agreement). As Pope Benedict XVI said in 2009, weakening is inevitable for the groups it recognizes. Rome is patient. She waited 11 years for the Society of St. Peter before requiring the clear, dramatic compromises. She waited 5 years for the Institute of Christ the King. She waited as long as needed for the inevitable weakening of each traditional society which she “recognized”.  

As the Vatican’s main negotiator with the SSPX said in the context of one particular conciliar error: “[T]he Traditionalists will not be able to accept [the conciliar teachings on the Jews] immediately. Convincing them will take time, and in this respect we will have to be patient.”  Source: http://vaticaninsider.lastampa.it/en/homepage/the-vatican/detail/articolo/society-of-st-pius-x-di-noia-16482/
