1 Corinthians 14:21

Tertullian Against Marcion Book V

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.[376]

Constitutions of the Holy Apostles Book VIII

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."[8]
