Clement of Rome

“ Wherefore let none of you exalt himself against his brother, though he be a prophet, or though he be a worker of miracles: for if it happens that there be no longer an unbeliever, all the power of signs will thenceforwards be superfluous. For to be pious is from any one’s good disposition; but to work wonders is from the power of Him that works them by us: the first of which respects ourselves ”

“ Thus signs do not shame all into belief, but only those of a good disposition; for whose sake also it is that God is pleased, as a wise steward of a family, to appoint miracles to be wrought, not by the power of men, but by His own will. Now we say these things, that those who have received such gifts may not exalt themselves against those who have not received them; such gifts, we mean, as are for the working of miracles. ”

“ 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 ”

“ Let not, therefore, any one that works signs and wonders judge any one of the faithful who is not vouchsafed the same: for the gifts of God which are bestowed by Him through Christ are various; and one man receives one gift, and another another. ”

“ And to be a Christian is in our own power; but to be an apostle, or a bishop, or in any other such office, is not in our own power, but at the disposal of God, who bestows the gifts. And thus much concerning those who are vouchsafed gifts and dignities.
Concerning Unworthy Bishops and Presbyters.
II. We add, in the next place, that neither is every one that prophesies holy, nor every one that casts out devils religious: for even Balaam the son of Beor the prophet did prophesy, [23] though he was himself ungodly ”
