OK, this must be said because it seems some people have read a different kind of interview than the one granted by the Superior General of the Priestly Fraternity of Saint Pius X (FSSPX / SSPX), Bishop Bernard Fellay, to the Fraternity's own news agency (DICI) and to the website of the Fraternity's United States District: there has been no "collapse" of "the doctrinal discussions between the Vatican and the SSPX", as this Catholic Herald columnist (and others) seem to imply. Fellay simply stated that the round of doctrinal discussions that had been agreed by both parties is "coming to a conclusion". That is it. No "collapse", but a simple matter already foreseen in the calendar of discussions.
If and when there is a "collapse", we will surely know it...
