1 Corinthians 14:23-25

Revised Standard Version Catholic Edition

²³ If, therefore, the whole church assembles and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are mad? ²⁴ But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, ²⁵ the secrets of his heart are disclosed; and so, falling on his face, he will worship God and declare that God is really among you.
