For a long time people have wondered about the "Instruction" that was to come from the Pontifical Commission Ecclesia Dei (now under the CDF) on the Holy Father’s "emancipation proclamation" Summorum Pontificum.
For some time I wondered whether it would be a good thing to have one. But over time I have come around to the idea a bit more, given that we have seen good leadership from the revised PCED.
Instruction on Summorum Pontificum should be imminent.
[...] The arrival also of the instruction of the Pontifical Commission Ecclesia Dei for the interpretation and application of the Pope’s Motu Proprio Summorum Pontificum…. is in the homestretch. At about three years since the release of the controversial papal document, groups of traditionalists have again denounced obstructionism by some bishops against the celebration of Mass with the Tridentine rite. To this are joined points of doubt and differences of interpretation of the norms. The awaited instruction should give the final word to these divisions. [Ignazio Ingrao]
Who knows what "imminent" means.
