Relevant Radio discussed this issue this afternoon; the host said, I think, that Latin Mass is a good thing every once in a while, but people need to know what is happening in the mass so having it in the local language is good for the congregation. Sounded like a good Lutheran argument 🤔
If you are a 60 year old (or younger) and a regular Sunday Mass attendee living in America, there is a very good chance you have never heard a Latin Mass. 60. If 65 you might have the vaguest of recollections of a Latin Mass.
There's such a thing as "catechesis" and also such a thing as a "missal". No reason for anyone except young children to not "know what is happening in the mass".
I'm glad you're listening to Relevant Radio, but they, too, say dumb things from time to time.
