(17) For thou verily givest thanks well.--It is here implied that speaking in a tongue was, as regards an individual, an acceptable mode of worship, and it is the public use of it that all throughout this passage the Apostle is dealing with.

Verse 17. - Well. It is good and honourable for thee to utter the voice of Eucharist; but if this be done in the unintelligible tongue, what does the Church profit? The other. The "layman" or "ungifted person."

14:15-25 There can be no assent to prayers that are not understood. A truly Christian minister will seek much more to do spiritual good to men's souls, than to get the greatest applause to himself. This is proving himself the servant of Christ. Children are apt to be struck with novelty; but do not act like them. Christians should be like children, void of guile and malice; yet they should not be unskilful as to the word of righteousness, but only as to the arts of mischief. It is a proof that a people are forsaken of God, when he gives them up to the rule of those who teach them to worship in another language. They can never be benefitted by such teaching. Yet thus the preachers did who delivered their instructions in an unknown tongue. Would it not make Christianity ridiculous to a heathen, to hear the ministers pray or preach in a language which neither he nor the assembly understood? But if those who minister, plainly interpret Scripture, or preach the great truths and rules of the gospel, a heathen or unlearned person might become a convert to Christianity. His conscience might be touched, the secrets of his heart might be revealed to him, and so he might be brought to confess his guilt, and to own that God was present in the assembly. Scripture truth, plainly and duly taught, has a wonderful power to awaken the conscience and touch the heart.For thou verily givest thanks well,.... In very proper words, and pertinent expressions, with great affection and devotion, suitable to the service;

but the other is not edified; the rest of the people, who do not understand the language in which thanks are given; "thy friend", as the Syriac version reads it; or thy next neighbour, he that stands by thee, receives no manner of profit by it, because he does not understand what is said.
