The fact that the motu proprio on the use of the Tridentine Missal, in force from September 14, has still not been published on the Acta, maybe in the expectation of solving some of the doubts which it brings, causes reflection....From [all of] this he wise decision to keep still in the boiling pan [lit. bain-marie] a text which is creating more problems than those which it does not solve: even at the cost of putting into force an act which exists (how to say it?) in "Web tantum".New Catholic reminds us:
Can. 7 A law comes into being when it is promulgated.Just to be sure, this is what the motu proprio says: "We order that everything We have decreed with this Apostolic Letter given Motu Proprio be considered as having full and lasting force, and be observed from September 14 of this year, Feast of the Exaltation of the Holy Cross, notwithstanding any provisions to the contrary."
Can. 8 §1 Universal ecclesiastical laws are promulgated by publication in the 'Acta Apostolicae Sedis', unless in particular cases another manner of promulgation has been prescribed. They come into force only on the expiry of three months from the date appearing on the particular issue of the 'Acta', unless because of the nature of the case they bind at once, or unless a shorter or a longer interval has been specifically and expressly prescribed in the law itself.
