Applause is appropriate when it is done in the name of God. i.e., applauding a 1st Communion is laudable because the community rightly celebrates the importance of this magnificent moment in the life of that child.

Miss Manners was asked once about applause in church. Her response: "If God wishes to applaud in church, He may. From anyone else, it's inappropriate."
