I doubt you will see the SSPX using the indult or asking for it. They have charted their course since 1981 with the "Declaration of Fidelity to the Positions of the SSPX": "Finally, I admit as being legitimate the liturgical reform of John XXIII. Hence I take all the liturgical books from it to be Catholic: the Missal, the Breviary, etc.; and I bind myself to make exclusive use of them according to their calendar and rubrics, in particular for the celebration of Mass and for the recitation in common of the Breviary." (emphasis added by me)
And it would seem logical that those of the Resistance who think themselves to be carrying the position of Archbishop Lefebvre would keep to this.
It would seem logical, if only logic could compete with the shameful Jansenist mind-set that predominates on the Traditionalist blogosphere. This is not advanced rocket science here. This is Jansenism vs. Catholicism 101. Both the liturgical reforms of St. Pope Pius X and the saintly Pope Pius XII chose to emphasise the apocalyptic nature of Roman Catholic history and the apocalyptic integration of Catholic nobles and Catholic peasant-workers into the Pan-European Imperial Roman Folk of the End Times. Their pontificates intentionally moved Holy Church away from the clericalism of the Ancien Régime towards a pro-active readiness for the Second Coming of Our Lord, which Catholic historic direction was led in the temporal realm by Napoleons I, II, III and IV, the good Kaiser Wilhelm II and the overwhelmingly Catholic Fortress Europe of the Axis Powers and then Nationalist Spain, Portugal, Ireland, South America, South Africa and so on. Including the strictly Francoist or pro-Spanish Vatican City State of Popes Pius XII and John XXIII.
Alas, Jansenist bloggers are not troubled by Catholic history or any objective realities of the human race. That would require courage, which is exactly the virtue that the timid Neo-Jansenists of the blogosphere most lack. How else explain the hopelessly un-Catholic contempt in which so many bloggers presume to hold the divinely-sanctioned Papal authority of Popes Pius X, Pius XII and John XXIII in their perfectly Roman Catholic liturgical reforms. The religious evils of the present time only go back to the completely illegal approval of Vatican Two in 1965 and to that piece of apostate sewage, Paul VI, and not to the Catholics on the Chair of Peter before the horrible Gramscian Communist Montini.In other words, Archbishop Lefebvre was right!!!
The liturgical reform of Pope John XXIII, completely consistent with the liturgical reforms of Popes Pius X and XII before that liturgical perfection, is absolutely the exclusive liturgy for the Latin Rite to use since July 1962. We ought to bind ourselves to make exclusive use of them, at least in so far as that is at all humanly possible for us. At least that is what Roman Catholics would do. (BTW, Bugnini was a typical bureaucratic robot: He did good when directed by Popes Pius XII and John XXIII, and evil when directed by the evil apostate Paul VI. Bugnini was a careerist chameleon who could never so much as tie his shoelaces without direction from his superiors.)Again, Archbishop Marcel Lefebvre was right!!!!
Let us follow his wise and saintly example. We should be faithful Papists, not gutless Neo-Jansenists. The liturgy of the old S.S.P.X. is the best one. The tormented (sort of-Pope) Benedict was right to follow the example of the good Archbishop in things liturgical in 2007, at least in commanding the liturgical reform of Pope John XXIII as the liturgy for exclusive use among the remnant little flock who can still be seriously described as Roman Catholics.
We are Papists, not Jansenist backsliders. Popes Pius X, Benedict XV, Pius XI, Pius XII, John XXIII and even the tragic and martyred John Paul I, were Roman Catholic Pontiffs. We obey their decisions. As for the apostates Paul VI, John Paul II and (horror of horrors) the Un-Francis Bergoglio, may the Devil take them, and the sooner the better.
(As for the hapless Benedict XVI, what an incomparable mess... Perhaps the "Last Pope" of legend, evidently.)
