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.
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?
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.
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.
