Apostolic Constitutions, on Isa 28:11

“For with the speech of lips, and with another tongue he will speak to this people.”

“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.”
