Intelligibility in Worship

14 Follow the way of love^(A) and eagerly desire^(B) gifts of the Spirit,^(C) especially prophecy.^{(D) 2} For anyone who speaks in a tongue^[a](E) does not speak to people but to God. Indeed, no one understands them;^(F) they utter mysteries^(G) by the Spirit. ³ But the one who prophesies speaks to people for their strengthening,^(H) encouraging^(I) and comfort. ⁴ Anyone who speaks in a tongue^(J) edifies^(K) themselves, but the one who prophesies^(L) edifies the church. ⁵ I would like every one of you to speak in tongues,^[b] but I would rather have you prophesy.^(M) The one who prophesies is greater than the one who speaks in tongues,^[c] unless someone interprets, so that the church may be edified.^(N)

⁶ Now, brothers and sisters, if I come to you and speak in tongues, what good will I be to you, unless I bring you some revelation^(O) or knowledge^(P) or prophecy or word of instruction?^{(Q) 7} Even in the case of lifeless things that make sounds, such as the pipe or harp, how will anyone know what tune is being played unless there is a distinction in the notes? ⁸ Again, if the trumpet does not sound a clear call, who will get ready for battle?^{(R) 9} So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air. ¹⁰ Undoubtedly there are all sorts of languages in the world, yet none of them is without meaning. ¹¹ If then I do not grasp the meaning of what someone is saying, I am a foreigner to the speaker, and the speaker is a foreigner to me.^{(S) 12} So it is with you. Since you are eager for gifts of the Spirit,^(T) try to excel in those that build up^(U) the church.

¹³ For this reason the one who speaks in a tongue should pray that they may interpret what they say.^{(V) 14} For if I pray in a tongue, my spirit prays,^(W) but my mind is unfruitful. ¹⁵ So what shall I do? I will pray with my spirit,^(X) but I will also pray with my understanding; I will sing^(Y) with my spirit, but I will also sing with my understanding. ¹⁶ Otherwise when you are praising God in the Spirit, how can someone else, who is now put in the position of an inquirer,^[d] say “Amen”^(Z) to your thanksgiving,^(AA) since they do not know what you are saying?
