Today in the old calendar is the Nineteenth Sunday after Pentecost. [Indeed, it is.]
It’s also September 29, the feast of the Dedication of the Basilica of St. Michael. [Indeed, it is.]
Propers for the TLM I attended today were for the latter. Should’t they have been for the former? [Indeed, according to my understanding, and my Ordo, that is so.]
In the old calendar, is it licit to make that kind of substitution? I see discussion online about the “external solemnity” of Corpus Christi (celebrating it on Sunday instead of, or in addition to, the preceding Thursday) but none about other feast days in the calendar. [Usually we don’t shove out the greater in favor of the lesser, do we.]
This wasn’t a matter of transferring the Mass for St. Michael to the nearest Sunday, since this year it happens to fall on a Sunday. [Indeed, that is so.] But I thought that on Sunday we use the propers for that Sunday, not the propers for the feast day we would have been celebrating that day if it weren’t a Sunday (with maybe one or two exceptions, including Christmas).
“Green” Sundays after Pentecost, in the traditional Roman calendar are 2nd class feasts. St. Michael, Michaelmas, is a 1st class feast. Thus, Michael gets the spotlight today. But we don’t just ignore the Sunday.
In the Extraordinary Form today we celebrate St. Michael, actually the Dedication of (the Church/Santuary of) St. Michael the Archangel, and we have as a commemoration the prayers for 19th Sunday after Pentecost. That is to say, the Mass formula is for St. Michael, and then we double-up the three major orations, following each one for Michaelmas with those we would have said had this been a normal 19th Sunday after Pentecost.
The best of both worlds, as it were.
We would observe the same for 2nd Vespers today.
Just so that you are not too disappointed on this fine feast, here is a sermon for Michaelmas:
Again, I am not sure why, the player may “hang”. Sometimes, it does, sometimes it doesn’t.
