1 Corinthians 14:13-25

New Revised Standard Version, Anglicised Catholic Edition

¹³ Therefore, one who speaks in a tongue should pray for the power to interpret. ¹⁴ For if I pray in a tongue, my spirit prays but my mind is unproductive. ¹⁵ What should I do then? I will pray with the spirit, but I will pray with the mind also; I will sing praise with the spirit, but I will sing praise with the mind also. ¹⁶ Otherwise, if you say a blessing with the spirit, how can anyone in the position of an outsider say the ‘Amen’ to your thanksgiving, since the outsider does not know what you are saying? ¹⁷ For you may give thanks well enough, but the other person is not built up. ¹⁸ I thank God that I speak in tongues more than all of you; ¹⁹ nevertheless, in church I would rather speak five words with my mind, in order to instruct others also, than ten thousand words in a tongue.

²⁰ Brothers and sisters,^[a] do not be children in your thinking; rather, be infants in evil, but in thinking be adults. ²¹ In the law it is written,

says the Lord. ²² Tongues, then, are a sign not for believers but for unbelievers, while prophecy is not for unbelievers but for believers. ²³ If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are out of your mind? ²⁴ But if all prophesy, an unbeliever or outsider who enters is reproved by all and called to account by all. ²⁵ After the secrets of the unbeliever’s heart are disclosed, that person will bow down before God and worship him, declaring, ‘God is really among you.’
