21 In the law it is written, "By people of strange tongues and by the lips of foreigners I will speak to this people; yet even then they will not listen to me," says the Lord. 22 Tongues, then, are a sign not for believers but for unbelievers, while prophecy is not for unbelievers but for believers. 23 If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are out of your mind? 24 But if all prophesy, an unbeliever or outsider who enters is reproved by all and called to account by all. 25 After the secrets of the unbeliever's heart are disclosed, that person will bow down before God and worship him, declaring, "God is really among you."

26 What should be done then, my friends? When you come together, each one has a hymn, a lesson, a revelation, a tongue, or an interpretation. Let all things be done for building up. 27 If anyone speaks in a tongue, let there be only two or at most three, and each in turn; and let one interpret. 28 But if there is no one to interpret, let them be silent in church and speak to themselves and to God. 29 Let two or three prophets speak, and let the others weigh what is said. 30 If a revelation is made to someone else sitting nearby, let the first person be silent. 31 For you can all prophesy one by one, so that all may learn and all be encouraged. 32 And the spirits of prophets are subject to the prophets, 33 for God is a God not of disorder but of peace. (As in all the churches of the saints,

34 women should be silent in the churches. For they are not permitted to speak, but should be subordinate, as the law also says. 35 If there is anything they desire to know, let them ask their husbands at home. For it is shameful for a woman to speak in church.

36 Or did the word of God originate with you? Or are you the only ones it has reached?) 37 Anyone who claims to be a prophet, or to have spiritual powers, must acknowledge that what I am writing to you is a command of the Lord. 38 Anyone who does not recognize this is not to be recognized. 39 So, my friends, be eager to prophesy, and do not forbid speaking in tongues; 40 but all things should be done decently and in order.

Commentary on 1 Corinthians 14:15-25

(Read 1 Corinthians 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.

Commentary on 1 Corinthians 14:26-33

(Read 1 Corinthians 14:26-33)

Religious exercises in public assemblies should have this view; Let all be done to edifying. As to the speaking in an unknown tongue, if another were present who could interpret, two miraculous gifts might be exercised at once, and thereby the church be edified, and the faith of the hearers confirmed at the same time. As to prophesying, two or three only should speak at one meeting, and this one after the other, not all at once. The man who is inspired by the Spirit of God will observe order and decency in delivering his revelations. God never teaches men to neglect their duties, or to act in any way unbecoming their age or station.

Commentary on 1 Corinthians 14:34-40

(Read 1 Corinthians 14:34-40)

When the apostle exhorts Christian women to seek information on religious subjects from their husbands at home, it shows that believing families ought to assemble for promoting spiritual knowledge. The Spirit of Christ can never contradict itself; and if their revelations are against those of the apostle, they do not come from the same Spirit. The way to keep peace, truth, and order in the church, is to seek that which is good for it, to bear with that which is not hurtful to its welfare, and to keep up good behaviour, order, and decency.
