1 Corinthians 14:23-28

23So if the whole church comes together and everyone speaks in tongues, and some who are uninstructed or some unbelievers come in, will they not say that you are out of your minds? 24But if an unbeliever or uninstructed person comes in while everyone is prophesying, he will be convicted and called to account by all, 25and the secrets of his heart will be made known. So he will fall facedown and worship God, proclaiming, “God is truly among you!”

26What then shall we say, brothers? When you come together, everyone has a psalm or a teaching, a revelation, a tongue, or an interpretation. All of these must be done to build up the church.

27If anyone speaks in a tongue, two, or at most three, should speak in turn, and someone must interpret. 28But if there is no interpreter, he should remain silent in the church and speak only to himself and God.
