I think. This morning there was a substitute priest for the pastor at the UA Mass. the Mass was done for St. Anselm, a doctor of the church. I noted the Credo was to be added, but the supply priest (of the Sainted Fr. S's vintage) added the Gloria, and didn't do the Creed.
UNLESS this was some tweak put in in the '62 Missal as opposed to prior ones. Which wouldn't have made sense. Given he was a doctor who defended the Creed against those heretics in the east, it makes more sense to say the Creed rather than a Gloria. Whatever.
Still -- I think something like this would a nice little extra to do with a weekday Mass in honor of St. Anselm (and other doctors of the church.) Something, I expect, that got lost - along with various Octaves, etc.
I'd asked the deacon after Mass about this, but he wasn't sure, and I was in a rush to get to work. So if anyone can say: "No, it was supposed to be the Gloria, and not the Creed as was done" let me know.
What are the best webpages that might point out the various changes in the Missal done since, say, 1900 or thereabouts?
