1 Corinthians 14:23-28

23So if the whole church comes together and everyone speaks in tongues, and inquirers or unbelievers come in, will they not say that you are out of your mind? 24But if an unbeliever or an inquirer comes in while everyone is prophesying, they are convicted of sin and are brought under judgment by all,

25as the secrets of their hearts are laid bare. So they will fall down and worship God, exclaiming, “God is really among you!”

Good Order in Worship 26What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up. 27If anyone speaks in a tongue, two—or at the most three—should speak, one at a time, and someone must interpret.

28If there is no interpreter, the speaker should keep quiet in the church and speak to himself and to God.
