First Epistle Of Saint Paul To The Corinthians Chapter 14
The gift of prophesying is to be preferred before that of speaking strange tongues.
Follow after charity, be zealous for spiritual gifts; but rather that you may prophesy.  For he that speaketh in a tongue, speaketh not unto men, but unto God: for no man heareth. Yet by the Spirit he speaketh mysteries. But he that prophesieth, speaketh to men unto edification, and exhortation, and comfort. He that speaketh in a tongue, edifieth himself: but he that prophesieth, edifieth the church. And I would have you all to speak with tongues, but rather to prophesy. For greater is he that prophesieth, than he that speaketh with tongues: unless perhaps he interpret, that the church may receive edification.
1st Commentary Prophesy: That is, declare or expound the mysteries of faith. End of Commentary.
2nd Commentary  Not unto men: Viz., so as to be heard, that is, so as to be understood by them. End of Commentary.
But now, brethren, if I come to you speaking with tongues, what shall I profit you, unless I speak to you either in revelation, or in knowledge, or in prophecy, or in doctrine?Even things without life that give sound, whether pipe or harp, except they give a distinction of sounds, how shall it be known what is piped or harped?For if the trumpet give an uncertain sound, who shall prepare himself to the battle?So likewise you, except you utter by the tongue plain speech, how shall it be known what is said? For you shall be speaking into the air.There are, for example, so many kinds of tongues in this world; and none is without voice.
If then I know not the power of the voice, I shall be to him to whom I speak a barbarian; and he that speaketh, a barbarian to me. So you also, forasmuch as you are zealous of spirits, seek to abound unto the edifying of the church. And therefore he that speaketh by a tongue, let him pray that he may interpret. For if I pray in a tongue, my spirit prayeth, but my understanding is without fruit. What is it then? I will pray with the spirit, I will pray also with the understanding; I will sing with the spirit, I will sing also with the understanding.
3rd Commentary  Of spirits: Of spiritual gifts End of Commentary.
Else if thou shalt bless with the spirit, how shall he that holdeth the place of the unlearned say, Amen, to thy blessing? because he knoweth not what thou sayest. For thou indeed givest thanks well, but the other is not edified. I thank my God I speak with all your tongues. But in the church I had rather speak five words with my understanding, that I may instruct others also; than ten thousand words in a tongue. Brethren, do not become children in sense: but in malice be children, and in sense be perfect.
4th Commentary Amen: The unlearned, not knowing that you are then blessing, will not be qualified to join with you by saying Amen to your blessing. The use or abuse of strange tongues, of which the apostle here speaks, does not regard the public liturgy of the church, (in which strange tongues were never used,) but certain conferences of the faithful, ver. 26, etc., in which, meeting together, they discovered to one another their various miraculous gifts of the Spirit, common in those primitive times; amongst which the apostle prefers that of prophesying before that of speaking strange tongues, because it was more to the public edification. Where also not, that the Latin, used in our liturgy, is so far from being a strange or unknown tongue, that it is perhaps the best known tongue in the world. End of Commentary.
In the law it is written: In other tongues and other lips I will speak to this people; and neither so will they hear me, saith the Lord.Wherefore tongues are for a sign, not to believers, but to unbelievers; but prophecies not to unbelievers, but to believers.If therefore the whole church come together into one place, and all speak with tongues, and there come in unlearned persons or infidels, will they not say that you are mad?But if all prophesy, and there come in one that believeth not, or an unlearned person, he is convinced of all, he is judged of all.The secrets of his heart are made manifest; and so, falling down on his face, he will adore God, affirming that God is among you indeed.
How is it then, brethren? When you come together, every one of you hath a psalm, hath a doctrine, hath a revelation, hath a tongue, hath an interpretation: let all things be done to edification.If any speak with a tongue, let it be by two, or at the most by three, and in course, and let one interpret.But if there be no interpreter, let him hold his peace in the church, and speak to himself and to God.And let the prophets speak, two or three; and let the rest judge.But if any thing be revealed to another sitting, let the first hold his peace.
For you may all prophesy one by one; that all may learn, and all may be exhorted:And the spirits of the prophets are subject to the prophets.For God is not the God of dissension, but of peace: as also I teach in all the churches of the saints.Let women keep silence in the churches: for it is not permitted them to speak, but to be subject, as also the law saith.But if they would learn any thing, let them ask their husbands at home. For it is a shame for a woman to speak in the church.
Or did the word of God come out from you? Or came it only unto you?If any seem to be a prophet, or spiritual, let him know the things that I write to you, that they are the commandments of the Lord.But if any man know not, he shall not be known.Wherefore, brethren, be zealous to prophesy; and forbid not to speak with tongues.But let all things be done decently, and according to order.
I believe the meaning of speaking in tongues as in the charismatic movements of these days means something completely different than what it meant in the days of the Apostles 2,000 years ago. I believe in the days of the Apostles speaking in tongues simply meant to speak in a different language. In 1 Corinthians 14:18 Saint Paul says "I thank my God I speak with all your tongues", as in all your languages. In the 4th Commentary above it refers to the Latin language as being used in our liturgy, where strange tongues (languages) were never used. Latin remains the main official language of the Holy See and the Roman Rite of the Catholic Church.
Questions for charismatics (those that "speak in tongues"). If 1 Corinthians 14:22 says "Wherefore tongues are for a sign, not to believers, but to unbelievers" then why are you "speaking in tongues" in church where there are only believers? Referring to 1 Corinthians 14:23, if outsiders heard you "speaking in tongues" do you not think that they would "say that you are mad?" Referring to 1 Corinthians 14:27-28 (and elsewhere in 1 Corinthians 14 where it mentions interpret or plain speech) when you "speak in tongues" is there an interpreter there to translate what you just said?
