I'm trying to find a word for the responses which people utter during prayer recitals or general "praise the lord" sort of speeches (not in sermons). Let me try elucidating this via an example:
Priest: "blah blah blah"
Random Person: "amen"
Priest: "blah blah blah"
Random Person: "ooo, praise the lord"
Priest: "blah blah blah"
Random Person: some random quote praising the lord
The best example would be the stuff you see in movies, typically portrayed in African-American churches. I'm sure there's a word for it. Also, forgive me if the meaning is not clear.
