1 Corinthians 14:23-25

New Catholic Bible

²³ Therefore, if the whole Church has assembled and everyone is speaking in tongues, would not any uninstructed person or any unbeliever on entering conclude that you are all out of your minds? ²⁴ However, if everyone is prophesying and an unbeliever or uninstructed person should enter, he would be reproved by all and judged by all, ²⁵ and the secrets of his heart would be revealed. Then he would fall down and worship God, declaring, “God is truly in your midst.”
