1. Father Laguérie on the nature and date of the document:
I do not know anything in particular on the famous "Motu Proprio", which should, for that matter, be [released] in the form of a decree. The two Cardinals who last spoke to me about it did not absolutely know its date, even though their personal conviction was that it would certainly see the light of day.
The best [thing] to say is that nobody knows anything [about this] and that the Pope decides by himself at the moment, which corresponds quite well to his way of doing [things].
2. From an article by Brian Mershon released by The Remnant:
Msgr. Ignacio Barreiro, Rome-based consultant to Una Voce America, confirmed that his Vatican sources have said the long awaited and much-rumored motu proprio easing restrictions on the Traditional Roman rite of Mass should be issued by Easter.
“I have information from a serious high level source that it is likely the motu proprio will be published before Easter,” Msgr. Barreiro said.
Msgr. Barreiro also said that the expected timing of the Traditional Latin Mass document’s promulgation is consistent with an opinion he heard from several other sources several months ago. He emphasized it would be important to carefully study Sacramentum Caritatis to determine if it holds any keys to understanding the expected motu proprio.
