1 I told you to desire the greatest gifts, and that is why I bid you earnestly to pursue love, but of those other spiritual things of which I have spoken, in my opinion the best, the most useful, is prophecy or preaching.
2-4 And why? Because it instructs and builds and strengthens. To utter a spiritual language known only to God is to hold converse indeed with God, to allow the Spirit itself to utter its own mysteries, and that is good.
5 I would have you all to speak with such tongues as that; but this spiritual language, the tongue of God, needs interpretation; and through that interpretation man is blessed with something that comforts, consoles, and builds him up.
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?
