Ambrosiaster : The Lord said this about those whom he knew in advance would not believe in the Savior. For to speak in other tongues and with other lips is to preach the New Testament. — COMMENTARY ON PAUL'S EPISTLES Apostolic Constitutions : These gifts were first bestowed on us the apostles when we were about to preach the Gospel to every creature, and afterwards were of necessity afforded to those who had by our means believed; not for the advantage of those who perform them, but for the conviction of the unbelievers, that those whom the word did not persuade, the power of signs might put to shame: for signs are not for us who believe, but for the unbelievers, both for the Jews and Gentiles. For neither is it any profit to us to cast out demons, but to those who are so cleansed by the power of the Lord; as the Lord Himself somewhere instructs us, and shows, saying: "Rejoice not because the spirits are subject unto you; but rejoice, because your names are written in heaven." [Luke 10:20] Since the former is done by His power, but this by our good disposition and diligence, yet (it is manifest) by His assistance. It is not therefore necessary that every one of the faithful should cast out demons, or raise the dead, or speak with tongues; but such a one only who is vouchsafed this gift, for some cause which may be advantage to the salvation of the unbelievers, who are often put to shame, not with the demonstration of the world, but by the power of the signs; that is, such as are worthy of salvation: for all the ungodly are not affected by wonders; and hereof God Himself is a witness, as when He says in the law: "With other tongues will I speak to this people, and with other lips, and yet will they by no means believe." [Isaiah 28:11; 1 Corinthians 14:21] For neither did the Egyptians believe in God, when Moses had done so many signs and wonders; nor did the multitude of the Jews believe in Christ, as they believed Moses, who yet had healed every sickness and every disease among them. — Apostolic Constitutions (Book VIII), Section 1, I John Chrysostom : Yet surely it is no where written in the Law, but as I said before, he calls always the whole of the Old Testament, the Law: both the prophets and the historical books And he brings forward his testimony from Esaias the prophet, again covertly detracting from the glory of the gift, for their profit; nevertheless, even thus he states it with praise. For the expression, "not even thus," hath force to point out that the miracle was enough to astonish them; and if they did not believe, the fault was theirs. And wherefore did God work it, if they were not to believe? That He might in every case appear to do His part. — Homily on 1 Corinthians 36 Origen of Alexandria : Note that Paul refers to the prophetic writings also as the "law." In this passage he is quoting Isaiah [28:11] according to Aquila's translation, and not according to the Septuagint. — COMMENTARY ON 1 CORINTHIANS 4.65 Tertullian : When he mentions the fact that "it is written in the law," how that the Creator would speak with other tongues and other lips, whilst confirming indeed the gift of tongues by such a mention, he yet cannot be thought to have affirmed that the gift was that of another god by his reference to the Creator's prediction. In precisely the same manner, when enjoining on women silence in the church, that they speak not for the mere sake of learning (although that even they have the right of prophesying, he has already shown when he covers the woman that prophesies with a veil), he goes to the law for his sanction that woman should be under obedience. — Against Marcion Book V
