According to a well-placed intercept following today's presentation of the
motu proprio on the Tridentine Mass to a group of 30 bishops (see below), no mention was made of a publication date extensively delayed into the future.
Apparently, the understanding among the attendees was that, as with
yesterday's document on the reinstatement of the invariable 2/3 supermajority in papal elections, the text will be made public in the
Bollettino of the Holy See Press Office as early as Roman noon tomorrow.
As of this writing, the name of the decree has not yet materialized.... More as it comes in.
