In the three years since the promulgation of Summorum Pontificum that liberalize the traditional Mass now called the "extraordinary form," the rise in interest in liturgical tradition has been marvelous to see.
The figures on the number of EF Masses now available are impressive given the short period of time, but the importance of Summorum goes far beyond this aspect alone. Full access to preconcilar liturgical forms represents an openness to a tradition that had been previously been shut out in a period upheaval that gave many the impression that Catholic liturgy had somehow been totally reinvented in the postconciliar period. This was arguably a main reason for Summorum: to re-integrate the new with the old and restore the sense of continuity that Pope Benedict XVI speaks about.
What is important today are the reports, increasingly credible, that a new instruction is forthcoming that will place new restrictions on the celebration of the traditional rite, particularly as regards ordination of priests. Enough reports have reached my own inbox to lead me to believe that something is underway. If there is anything that can be done to prevent any pullback from Summorum, it should be done.
This is why I would strongly suggest go to motuproprioappeal.com/ and sign the petition right now. There are already more than 500 signatures.
