On this subject I think I am a fence sitter—-not knowing which way to jump in.
It is nice when the priest prompts an acknowledgement of the choir or musicians (in some parishes that is all the thanks they ever get—-and from what I know of the parishes I have been in
it requires alot of practice time)
Now that I think of it—another way to offer something is by mentioning them in the intentions or prayer of thanksgiving after communion.
I have been at weddings and babptisms where folks have clapped in celebration too.
But I do agree that after mass is ‘over’, even if it ends with some recognition by applause
the silent reverence should return so people can continue their prayers. The rest of the congregation should exit quietly and carry on visiting (which by the way is great fellowship) in the hall or out of doors.
