There is a belief, held by some, that one day the Roman mass as promulgated under Pope Paul VI will one day be rolled back and the “Traditional Latin Mass” restored as the only Rite of the West. Aside from the fact that the pre-existing Rites of Milan and Toledo make this an impossibility (unless these traditionalists wish to squash venerable tradition), reality makes this an impossibility. The Reformists in the Vatican like Cardinal Sarah and those who they will inevitably form will have no desire to try to restore the Rite of Trent and wind the clock back to 1570 (or 1870) and will instead likely work on fixing many of the deficiencies in the Roman Rite.
Maybe we will live to see Septuagesima imported into the Roman Rite or enforcement of Ad Orientum worship. Maybe there will be grounded and logical rules for when to use Eucharistic Prayers I-III while either making the never-used Eucharistic Prayer IV extinct or giving it the same treatment the Byzantine Rite gives to the Anaphora of St. James: extremely restricted but venerated use. Maybe Communion in the hand will be recognized as the bad idea it is and maybe… the ancient tradition of Infant Communion can finally be restored (one can dream) instead of ecclesiastics trying to push for communing the divorced and remarried (I could rant for hours on this point).
The Rite of Trent is here to stay, as is the Rite of Rome. The two will exist side-by-side in the same Church with priests likely having the liberty to say either. The Rite of Rome will develop and might even work in older rituals from the The Rite of Trent, but to think that it will be cast aside by a Pius IX returning from his grave is pure fantasy. Those who hold on to such beliefs will go the way of the sedevacantists, the conclavists, or Bishop Williamson and his “resistance”.
This is not without precedent either. The same thing happened in the Muscovite Church and is still the rule. Those wishing to hold to the Old Rituals may do so in that church and those who believe that church fell when the New Rituals were adopted have remained in their own severed (and sometimes priestless) communities. This allowance of different rituals even extends into the tiny Russian-Greek Catholic Church and has ever since Pius X welcomed them in.
Everything new is old and everything old is new again.
Besides, Old Believers do it better than 1950’s obsessed Latin Massers anyway
What further solidifies the poly-Ritualist nature of the Roman Church is the emergence of a new and beautiful Rite few could have foreseen: that used by the Anglican Ordinariates. When attending this Rite’s Masses I have wondered if this was what Bouyer and Jungmann imagined when they undertook their liturgical movement, but one can never know. If circumstances ever require me to leave Kievan Byzantium for a time, then I sincerely hope it is either to here or a reform-minded Roman Rite parish. I am personally forever done with the Rite of Trent, or rather, the culture and polemics one must deal with in most such communities.
Traditionalists will one day learn to live with this reality God has willed. If they do not, they will forever condemn themselves to the fate of the still severed Old Ritualists or to 1950’s American caricatured liturgical and cultural ghettos.
And is a ghetto truly what Christ had in mind when he said to “go out and preach to all nations”?
