1Cor 14:30

“But it happens, by a love of presumption and of obstinacy, that one would rather maintain his own evil and false position, than agree in the right and true which belongs to another. Looking forward to which, the blessed Apostle Paul writes to Timothy, and warns him that a bishop must not be "litigious, nor contentious, but gentle and teachable." Now he is teachable who is meek and gentle to the patience of learning. For it behoves a bishop not only to teach, but also to learn; because he also teaches better who daily increases and advances by learning better; which very thing, moreover, the same Apostle Paul teaches, when he admonishes, "that if anything better be revealed to one sitting by, the first should hold his peace." But there is a brief way for religious and simple minds, both to put away error, and to find and to elicit truth. For if we return to the head and source of divine tradition, human error ceases; and having seen the reason of the heavenly sacraments, whatever lay hid in obscurity under the gloom and cloud of darkness, is opened into the light of the truth. If a channel supplying water, which formerly flowed plentifully and freely, suddenly fail, do we not go to the fountain, that there the reason of the failure may be ascertained, whether from the drying up of the springs the water has failed at the fountainhead, or whether, flowing thence free and full, it has failed in the midst of its course; that so, if it has been caused by the fault of an interrupted or leaky channel, that the constant stream does not flow uninterruptedly and continuously, then the channel being repaired and strengthened, the water collected may be supplied for the use and drink of the city, with the same fertility and plenty with which it issues from the spring? And this it behoves the priests of God to do now, if they would keep the divine precepts, that if in any respect the truth have wavered and vacillated, we should return to our original and Lord, and to the evangelical and apostolical tradition; and thence may arise the ground of our action, whence has taken rise both our order and our origin.”

“"But if a revelation he made to another sitting by, let the first keep silence. For ye all can prophesy one by one, that all may learn, and all may be comforted." What may this be which is spoken? "If when thou prophesiest," saith he, "and art speaking, the spirit of another stir him up, be silent thenceforth." For that which he said in the case of the tongues, this also here he requires, that it should be done "in turn," only in a diviner way here. For he made not use of the very expression, "in turn?" but "if a revelation be made to another." Since what need was there further, that when the second was moved to prophesy the first should speak? Ought they then both? Nay, this were profane and would produce confusion. Ought the first? This too were out of place. For to this end when the one was speaking, the Spirit moved the other, in order that he too might say somewhat. So then, comforting him that had been silenced, he saith, "For ye all can prophesy one by one, that all may learn, and all may be comforted." Seest thou how again he states the reason wherefore he doeth all things? For if him that speaks with tongues he altogether forbid to speak, when he hath not an interpreter, because of the unprofitableness; reasonably also he bids restrain prophecy, if it have not this quality, but createth confusion and disturbance and unseasonable tumult.”

“For ye may all prophesy one by one,.... Not every member of the church, but everyone that had the gift of prophecy; so that they were not confined to two or three prophets at a meeting, but as many as would, or as had anything to deliver, and as time would allow; only care must be taken that confusion be avoided, and order preserved by exercising in turns one after another. This was agreeably to the custom of the Jewish synagogue, in which more might read and speak, though but one at a time; for "it is forbidden to read in the book of the law, except one only, that all may hearken, and be silent, that so they may hear the words from his mouth, as if they had heard them that very moment from Mount Sinai.'' So here, that all may learn; more of the doctrine of Christ, and of the mind and will of God, and attain to a greater knowledge in the mysteries of the Gospel, and in the duties of religion, even prophets and teachers as well as private members and common hearers; for there are none who know ever so much, but are capable of being further taught and instructed, and that sometimes by such whose gifts are interior to them: and all may be comforted; or exhorted, or receive exhortation. The word used signifies both; and prophecy is useful both for exhortation and comfort, and that both to preachers and people.”

“Be revealed to another that sitteth by - Probably those who were teachers sat on a particular seat, or place, from which they might most readily address the people; and this may be the meaning of sitting by. If such a person could say, I have just received a particular revelation from God, then let him have the liberty immediately to speak it; as it might possibly relate to the circumstances of that time and place.”

“If any thing--Translate, "But if any thing." another that sitteth by--a hearer. let the first hold his peace--Let him who heretofore spoke, and who came to the assembly furnished with a previous ordinary (in those times) revelation from God (Co1 14:26), give place to him who at the assembly is moved to prophesy by a sudden revelation from the Spirit.”
