Well, a statistician might not think so.
If you’re saying there’s a rumor that come next Advent the Church will require that some or all of every Mass be said in Latin, I haven’t heard any such, and the approved Ordo has been made public, and it doesn’t have any Latin. Nor does Liturgiam Authenticam call for it, and none of the people involved in the process, from the top to the bottom, have said anything except that the new translation will all be in English. It would also be strange, since that would mean that an “English” Mass would by requirement be partly in Latin, while Mass in every other language (the ones which are not getting new books next Advent) would remain entirely in the vernacular.
Don’t misunderstand, I think it would be
great if some Latin were required, but I wanted to point out that we do a disservice to people who have concerns and misgivings about “So now my Mass will be in Latin?!” if we don’t first assuage their concerns. Let them know that they will still have English, and
then try to persuade them that they ought to want Latin. There’s no reliable reason to think otherwise, and a very large corpus of highly reliable reasons to think that the 100% English Mass will continue to be just as licit as it is today.
Most of the people who ask these kinds of questions are concerned about what will happen at
their parish, not about hypothetical cases in which a multi-language Mass is celebrated by choice. So by all means it’s true that a pastor under the new translations
could do part of the Mass in Latin, but that’s a power he has today – and applies to Latin equally as to Spanish or Creole – and it has nothing to do with the translations, so there is no reason to expect any change on that front just because the English texts are changing. Latin will not be forced on a parish whose pastor doesn’t want it, just as it isn’t today.
