But if all prophesy - See the note at 1 Corinthians 14:1. If all, in proper order and time, shall utter the truths of religion in a language intelligible to all.

Or one unlearned - One unacquainted with the nature of Christianity, or the truths of the gospel.

He is convinced of all - He will be convinced by all that speak. He will understand what is said; he will see its truth and force, and be will be satisfied of the truth of Christianity. The word here rendered "convinced" (ἐλέγχετἀι elengchetai) is rendered "reprove" in John 16:8, "And when he is come, he will reprove the world of sin," etc. Its proper meaning is to "convict," to show one to be wrong; and then to rebuke, reprove, admonish, etc. Here it means, evidently, that the man would be convicted, or convinced of his error and of his sin; he would see that his former opinions and practice had been wrong; he would see and acknowledge the force and truth of the Christian sentiments which should be uttered, and would acknowledge the error of his former opinions and life. The following verse shows that the apostle means something more than a mere convincing of the understanding, or a mere conviction that his opinions had been erroneous. He evidently refers to what is now known also as "conviction" for sin; that is, a deep sense of the depravity of the heart, of the errors and follies of the past life, accompanied with mental anxiety, distress, and alarm. The force of truth, and the appeals which should be made, and the observation of the happy effects of religion, would convince him that he was a sinner, and show him also his need of a Saviour.

He is judged by all - By all that speak; by all that they say. The "effect" of what they say shall be, as it were, to pass a "judgment" on his former life; or to condemn him. What is said will be approved by his own conscience, and will have the effect to condemn him in his own view as a lost sinner. This is now the effect of faithful preaching, to produce deep self-condemnation in the minds of sinners.

But if all prophecy - If all those who teach do it in the tongue which all understand; if an unbeliever, or one who knows nothing of the sacred language, come in and hear things just suited to his own state, he is convicted by all, and he is judged by all.

But if all prophecy,.... That is, all that speak publicly in the church, not together, but in their order, one after another, as is hereafter directed:

and there come in one that believeth not, or one unlearned; an unbeliever that has only the knowledge of his mother tongue, in which prophesying or preaching is used:

he is convinced of all, he is judged of all; of all the prophets or preachers; they all reprove him, and detect his secret, as the Arabic version renders the words; and to the same purport the Ethiopic. This must be understood of such persons whom the Spirit of God, under, and by the ministry of the word, powerfully works upon; whose hearts he opens to receive the word, and to whom he effectually applies it; whom he convinces of sin, righteousness, and judgment, shows the evil of their hearts and ways, reproves their errors, convicts them of their mistakes, and informs their judgments, and condemns all their principles and practices which are not agreeably to the word of God.

Convinced (ἐλέγχεται)

Of his sins. See on tell him his fault, Matthew 18:15; see on convinced, James 2:9; see on reproved, John 3:20. Rev., reproved: convicted in margin.

Judged (ἀνακρίνεται)

Examined and judged. The word implies inquiry rather than sentence. Each inspired speaker, in his heart-searching utterances, shall start questions which shall reveal the hearer to himself. See on discerned, 1 Corinthians 2:14. On the compounds of κρίνω, see on 1 Corinthians 11:29, 1 Corinthians 11:31, 1 Corinthians 11:32.

But if all prophesy, and there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all:

14:24 But if all prophesy. Those speaking would then speak what would be understood, and, speaking under the divine impulse, would convict.

He is convinced of all, he is judged of all. His state and character are laid bare by the speakers.

14:24 He is convicted by all - who speak in their turns, and speak to the heart of the hearers. He is judged by all - Every one says something to which his conscience bears witness.

24. all-one by one (1Co 14:31).

prophesy-speak the truth by the Spirit intelligibly, and not in unintelligible tongues.

one-"anyone." Here singular; implying that this effect, namely, conviction by all, would be produced on anyone, who might happen to enter. In 1Co 14:23 the plural is used; "unlearned or unbelievers"; implying that however many there might be, not one would profit by the tongues; yea, their being many would confirm them in rejecting the sign, as many unbelieving men together strengthen one another in unbelief; individuals are more easily won [Bengel].

convinced-convicted in conscience; said of the "one that believeth not" (Joh 16:8, 9).

judged-His secret character is opened out. "Is searched into" [Alford]. Said of the "one unlearned" (compare 1Co 2:15).

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.
