16. Then will those who hearken to your blessing and giving of thanks say Amen to it. For the demands of the understanding have been fulfilled.
17. But if you give thanks with spiritual voices only, in a language unknown to those who fill the place of the humble listeners and the congregation, however well you do it, the church is not fulfilled and is not edified.
18. My brethren, this language of the Spirit utters itself richly in me, and in more frequent and fuller tones than in all of you,
19. yet would I rather speak five words with the understanding that can help my brother than ten thousand in a language which he does not know.
20. My brethren, you have become as little children in this world, but be not children in understanding, but children only in evil. This speaking with tongues, you say, is a sign, a miracle.
21. Yes, God says, “With other lips and a strange tongue will I speak to this people, and yet will they not hearken to me.” (Is. xxviii. 11-12)
22. They are a sign to those who have no faith, and a sign that is not accepted.
23. In your own midst, when the whole church is gathered together as one, what need then of such strange and startling signs?
24. For then are heard the voices of understanding that build the perfect church, psalm, and teaching, revelation, tongues and their interpretation; and when one from without enters this reasonable temple of worship,
25. the thoughts of his own heart are laid bare to him, he is convicted and judged and made to cry out in his own soul, “surely God is in you” (Is. xlv. 14).
26. To this great aim let all your worship tend; let psalm, teaching, revelation, tongues and their interpretation be subject to order and arrangement, and so help to build the church.
27. Let not more than two or three at most speak with tongues simultaneously, and let these utterances of the Spirit invariably be interpreted and let them not be too long.
28. Without interpretation there must be no speaking with tongues. Let him who feels this ability commune with himself and with God, and be silent in his ecstasy, unless he can make his meaning clear.
29. Let not more than two or three members speak as prophets voicing the divine,
30. and let the rest listen in silence, and distinguish carefully the truth of the words spoken; and where one or other is moved by revelation to speak, give place to him and let the first be silent.
31-32. For everyone of you, and not a few only, is able to prophesy, and to do this for the good of all, for there is nothing unruly in the spirit of prophecy. It is subject to him who has the understanding of it,
33. and in the churches of God all is order and peace. There is no disorder in the divine being.
