6-7. Prophecy does this, interpreting to others the language of heaven, and building the Church on earth. Therefore is it a greater gift to prophesy than to speak the new tongues of the Spirit, for such words make the Church. The new tongues require interpretation. I shall be no help to you unless I reveal something to you, increase your knowledge of things divine, and act as a prophet and teacher. All tongues and languages and voices on earth have meaning.
8. Even the trumpet, made of brass merely, can summon men to battle, the flute and the pipe can move men most variously. But what if their sounds be not understood? What if their stops and notes be so uncertainly handled that there is no recognition of their meaning? Who will arm himself then for the fray?
9-10. And of the different languages which men talk, there is not one which is without meaning and interpretation. We call those “foreign” tongues which we cannot understand, and them that speak them “foreigners.” So it is with the language of heaven, the tongue that the Spirit speaks with spiritual utterings.
11. It sounds strange and barbarous in the ears of those who do not understand it. It needs interpretation, and for those who understand it not, you do but speak into the air, not into their minds.
12-13. If you be anxious and desirous for proofs of your spirituality, for the gifts and wonders of the Spirit and its activities, then let this desire for an overflowing measure of it in your hearts end always in the furthering of that great spiritual goal, the aim, as I have said, of all the operations of the Spirit, the building up of the Church, of the infinite body of the Christ.
14. To that end pray and sing, bless and give thanks.
15. If I pray with the mind as well as the Spirit, and sing with understanding as well as ecstasy, and interpret to the mind and consciousness the tongue of the Spirit which I utter, then is that great purpose fulfilled.
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.
