I am a big supporter of vernacular in liturgy. I recently held up this Western Rite Orthodox celebration as approaching my ideal, for example, which would basically be to use translations of the Propers of the Old Mass according to a nice "thee and thou" kingly English translation (ala the Anglican Missal or English Missal), leave the Ordinary in Latin, and make the priest's spoken "private devotional" parts (Prayers at the Foot of the Altar, Offertory, Communion prayers, Last Gospel, etc) audible but probably in the vernacular, as I sort of hate the practice of "singing over" parts of the Mass or using motets at High Mass, etc.
Some of what I am about to suggest might then sound a bit counter-intuitive, as it involves both a whole lot of "singing over" and the possibility of vernacular for even the Ordinary of the Mass, though the point of the latter would be to "ease people into" the Old Mass who are entirely unfamiliar, who only know the vernacular Novus Ordo.
In fact, I also thought-up once a graduated system of different "internally consistent" combinations of music and/or language that I'd like to see approved for the Old Mass (given that one of my pet peeves at the Novus Ordo is inconsistency in this regard; where, for example, a priest will chant the collect at the beginning but then only read the postcommunion, or where the Agnus Dei is randomly in Latin even though none of the rest of the Ordinary was, etc). That system would be nice, but what I'm saying here now, however, is an attempt to work "within" the current rules.
Basically, I had this idea during university that the permission/tradition of having vernacular hymns sung at/over a Low Mass, and even to have private devotions (like the rosary) being prayed aloud in the church at the same time, could be used to, essentially, create a "virtual" Old Mass in English, or to make a Low Mass into a sort of virtual High Mass (whether Latin or vernacular).
The idea was essentially: fine, have the priest praying his Low Mass entirely spoken and in Latin, but if the congregation is free to extra-liturgically sing hymns (including vernacular hymns) or pray prayers "unofficially" while that's going on...why not have them sing the Ordinary during Low Mass, "unofficially" as "hymns"? If we're allowed to "unofficially" sing hymns (Latin or vernacular) over the Low Mass, why couldn't those hymns be the Mass itself?
And, what's more, why not have them sing/chant a vernacular translation of the actual Proper antiphons while the priest reads them quietly up at the altar (and, ideally, waits for the congregation to finish singing; a big part of what I dislike about "singing over" Mass parts is how the priest often "moves on with" his Mass independent of the choir and so the whole thing gets disjointed/out of synch). Or even pray the priest's "private devotional" parts out loud in the vernacular as their own congregational "private devotion"? Heck, maybe even the collects or readings could be sung by the choir as "hymns" over the corresponding parts (there is also, of course, the permission to read the lessons in the vernacular to consider too.)
However, I was told by some, this was forbidden. They insisted: you can sing anything at Low Mass except the Ordinary or Propers (in Latin or the vernacular). On the one hand, this extremely frustrated me and seemed bizarre and impossible (how can what the congregation sings be legislated with reference to the Low Mass, if the Low Mass is technically "private" anyway with the congregation technically just "observing"?)
On the other hand, it made some sad sense: if the Vatican was trying to resist a vernacular liturgy tooth-and-nail (until it finally gave up and gave in), allowing a "virtual" one to be created through basically layering an "unofficial" translation as "hymns" or "private prayers" over a silent Low Mass...would be sort of a cheat or loophole they might want to close (I was sad they were clever or prescient enough to do that.) And at that point I'd rather Low Mass just be spoken, then, as a dialogue (because I don't really like using totally extra-liturgical hymns, Latin or vernacular, at any sort of Mass, except maybe the seasonal Marian Antiphon for the recessional...but then, that isn't totally extra-liturgical.)
However, an event I recently saw advertised on the blog of Una Voce Toronto (which I missed, unfortunately; I wish I had known of it) apparently put something into practice which would suggest to me it isn't entirely forbidden as some sources claim. Basically they had a Low/Read Dialogue Mass (though I hate that some people treat the "Dialogue Mass" as a separate category: all Masses should be dialogue Masses! The people should make their responses and recite or sing the Ordinary!) with hymns and motets (as is usual). But the interesting thing was that this time some of the "hymns" were going to include singing the Latin Ordinary parts from Mass VIII (I know, not my favorite, but well-known) over the corresponding parts of the Low Mass.
And if this can be done, of course, the jump to doing that for the Propers too, or for either in the vernacular...is inevitable. If unofficially singing Mass parts over a Low Mass is allowed, and vernacular hymns are allowed, then unofficial vernacular translations of Mass parts as "hymns" can't logically be forbidden.
So I did some research and found this Fr. Z thread where quite a debate once raged. While some people put forward the "you can basically sing anything at Low Mass, Latin or vernacular, except Mass parts or translations thereof" interpretation, other voices said this was a misunderstanding of the relevant decrees, that it only applied to the priest, or that this was definitely not true, or wasn't any longer at least, or that at least there were no definitive sources saying you can't (and some even citing sources seeming to approve the practice as regards the Latin Ordinary).
So, it seems to me now that the practice is not definitively condemned! It is at least ambiguous as to whether this is allowed, and what is ambiguous may be done and is apparently practiced some places sometimes (including here apparently). Certainly, I don't think anyone could try to claim it was unambiguously illicit (after all, maybe a choir is just "practicing" for a vernacular Novus Ordo later, and a priest "just happens to be" saying his "private" Low Mass in the same church in a manner that "coincidentally" syncs perfectly with that, lol!)
You'd have to be careful about who you let see it. A rad trad who came expecting to pray their rosary during an entirely silent Low Mass might get a rude awakening and raise a hubbub with Ecclesia Dei or something like that. But, still, the possibility is intriguing if one could find a priest and choir willing to participate in such a venture...
