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.
