Saying Amen in Church

QUESTION: Is it essential that we say Amen as a sanction to the truth? The church authorities forbid it as disorderly.

ANSWER: This is a matter of taste rather than of religious obligation. It seems desirable that audiences should be responsive to the speaker, but not in a boisterous way by very loud and frequent ejaculations. A quiet amen now and then helps and encourages a speaker, but too many and too often may confuse him.
