I have a friend who will love the "applause" thing. She hates it when people applaud at the end of a Mass.
Do you know that in Rome, at the end of the Mass when the Pope is processing out, the congregation always claps and cheers him on. Quite enthusiastically, too. And it's not just the Pope. I went to a Mass celebrated by Cardinal Ruini and they did the same thing with him.
If Mass is not made into a theatrical performance, there won't be applause.
This applies equally to those who want to see Opera House Mozart Masses performed in the Old Rite as to those who make the Novus Ordo into a stage act.
