Bishop Schneider has called for the SSPX to be given the justice they were denied in the 1970s. I do wonder, with great respect to his Lordship, whether things are now any longer quite as simple as that.
For a decade or two, we have been told that regularisation must wait upon the acceptance by the Society of the teaching of Vatican II and of the post-Conciliar Magisterium. But given the way things are now, might it not be fair and equitable for the Society now to insist that Papa Bergoglio manifest a proper and unambiguous submission to the post-Conciliar Magisterium of S John Paul II and of Benedict XVI? And, in particular, that he enact (perhaps as part of a deal with the Society) a solemn reconfirmation in his own name of Veritatis splendor, Familiaris consortio, and Summorum Pontificum?
The Roman Pontiff, suspiciously, has already declined to to give the very simple answers requested of him to the effect that Veritatis splendor and Familiaris consortio still, as it were, apply. And on November 20, I expressed a fear that a regularisation of the SSPX might be accompanied by a cancellation, or evisceration, of Summorum Pontificum. Indeed, on 21 September 2016 Sandro Magister had reported somebody called Andrew Grillo (Alcuin Reid's sparring partner??) as opining that the next Synod would discuss "the collegial exercise of the episcopate and the restitution to the bishop of full authority over diocesan liturgy". It was pretty obvious to me what the nasty little phrase I italicise was code for, as I wrote a few days later on my blog. In the event, we were reprieved; a different topic was to be selected for the next Synod (Youff, I think), possibly because Bergoglio is decent enough still to have some reticence about too overt a public humiliation of Joseph Ratzinger while he is still alive. But Grillo's expectations are unlikely to have been entertained by him alone.
There has always been a practical certainty that a certain sort of bishop, for whom 'subsidiarity' means I Must Be Free To Ban Everything That Isn't To My Personal Taste, would not easily abandon his hopes of (at least) limiting and controlling worship according to the Old Rite. In one of the Ordinariates (not the British one!) a local bishop put pressure some years ago on the Ordinary to prevent the use of the Extraordinary Form within that Ordinariate. Readers will not need to be reminded of the savage humiliations inflicted, and by a Roman Dicastery, upon the Franciscan Friars and Sisters of the Immaculate; humiliations which are still, as far as I know, in place. There was an American bishop who required clergy to pass a test in Latin to prove that they were idonei to celebrate the Old Mass ... typical piece of Liberal nastiness, isn't it ... you arrange for your clergy, contra canonem, to be ordained without having been taught Latin, then you jeer and sneer at them for not knowing it. At a jollier level, English clergy may remember how Cardinal Murphy-O'Connor acquired, for a year or two, the nickname of "The Envisager" because he attempted to circumscribe Summorum Pontificum by issuing a whole lot of comically panic-ridden rubbish making use of the phrase "It is envisaged that ..." [NB good example of Management-talk using the impersonal passive construction].
Bigotry still abounds.
Archbishop Lefebvre's Society always insisted that they were not begging to be allowed to exist as a tolerated ghetto. They insisted that they would only do a deal if every Latin Rite priest were allowed, without needing special faculties or permissions, to offer the authentic Roman Rite. Accordingly, the entire point of Summorum Pontificum was to call their bluff by giving precisely what they had demanded, and returning the Usus Antiquior to the whole Latin Church. This represented an authoritative removal of the old 'Indult' culture, in which it was only allowed within personal parishes served by organisations such as FSSP and ICKSP, or where it was permitted by an indulgent Diocesan.
Were some deal to be put before the SSPX, accompanied by suspicions that there might be a diminution in the right of every Latin Rite priest to offer the Old Mass, I very much hope that His Excellency Bishop Fellay would refuse it. Or would indicate that, in such a possible future eventuality, he would unilaterally suspend certain of the articles in his agreement with the Vatican. A firm hand on the tiller would be a very great service to the entire Latin Church.
I write this as someone who have, for years, said the prayer Domine Iesu Christe, qui dixisti in all my Masses with an intention for the canonical regularisation of the SSPX. Regularisation would afford great benefits both to the entire Latin Church, and to the Society; not least by providing a refuge of incardination for clergy being intimidated elsewhere (any provision excluding the Society from exercising the right to incardinate would be ... very dodgy .... very fishy ..... ). I hope the terms agreed would include a provision for the Agenda of each Episcopal Conference to be sent in good time to the Superior of the Society, so that he or one of the other bishops could attend a meeting and explain why some particular proposal would have a divisive effect. After all, the whole point of enhancing the authority of Episcopal Conferences is to encourage divisiveness. Isn't it?
Capitulation is not the way ahead.
