"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, (Num_23:1-30 and Num_24:1-25) though he was himself ungodly; as also did Caiaphas, the falsely-named high priest. Nay, the devil foretells many things, and the demons, about Him; and yet for all that, there is not a spark of piety in them: for they are oppressed with ignorance, by reason of their voluntary wickedness. It is manifest, therefore, that the ungodly, although they prophesy, do not by their prophesying cover their own impiety; nor will those who cast out demons be sanctified by the demons being made subject to them: for they only mock one another, as they do who play childish tricks for mirth, and destroy those who give heed to them. For neither is a wicked king any longer a king, but a tyrant; nor is a bishop oppressed with ignorance or an evil disposition a bishop, but falsely so called, being not one sent out by God, but by men."Constitution of the Apostles
Bk. 8 Pt. 1 Ch. II, Vol. 7

"But there were others too, who, as if elated by the Holy Spirit and the prophetic gift, and not a little puffed up, and forgetting entirely the Lord’s distinction, challenged the maddening and insidious and seductive spirit, being themselves cajoled and misled by him, so that there was no longer any checking him to silence."Asterius Urbanus
Extra Writings Ch. II, Vol. 7

"But the spirit of deceit preaches himself, and speaks his own things, for he seeks to please himself. He glorifies himself, for he is full of arrogance. He is lying, fraudulent, soothing, flattering, treacherous, rhapsodical, trifling, inharmonious, verbose, sordid, and timorous."Ignatius (Disciple of Apostle John)
Epistle to Ephesians Bk. 2 Ch. IX, Vol. 1

"For this end did the Lord suffer the ointment to be poured upon His head, (Comp. Joh_12:7) that His Church might breathe forth immortality. For saith [the Scripture], “Thy name is as ointment poured forth; therefore, have the virgins loved Thee; they have drawn Thee; at the odor of Thine ointments we will run after Thee.” (Son_1:3-4) Let no one be anointed with the bad odor of the doctrine of [the prince of] this world; let not the holy Church of God be led captive by his subtlety, as was the first woman. Why do we not, as gifted with reason, act wisely? When we had received from Christ, and had grafted in us the faculty of judging concerning God, why do we fall headlong into ignorance? and why, through a careless neglect of acknowledging the gift which we have received, do we foolishly perish?"Ignatius (Disciple of Apostle John)
Epistle to Ephesians Bk. 2 Ch. XVII, Vol. 1

"It appears probable enough that this man possesses a demon as his familiar spirit, by means of whom he seems able to prophesy, ([Comp. Act_16:16]) and also enables as many as he counts worthy to be partakers of his Charis themselves to prophesy."Iranaeus
Against Heresies Bk. 1 Ch. XIII, Vol. 1

"But already some of the most faithful women, possessed of the fear of God, and not being deceived (whom, nevertheless, he did his best to seduce like the rest by bidding them prophesy), abhorring and execrating him, have withdrawn from such a vile company of revelers. This they have done, as being well aware that the gift of prophecy is not conferred on men by Marcus, the magician, but that only those to whom God sends His grace from above possess the divinely-bestowed power of prophesying; and then they speak where and when God pleases, and not when Marcus orders them to do so."Iranaeus
Against Heresies Bk. 1 Ch. XIII, Vol. 1

“The fact that there are such men confessing themselves to be Christians, and admitting the crucified Jesus to be both Lord and Christ, yet not teaching His doctrines, but those of the spirits of error, causes us who are disciples of the true and pure doctrine of Jesus Christ, to be more faithful and steadfast in the hope announced by Him. For what things, He predicted would take place in His name, these we do see being actually accomplished in our sight. For he said, ‘Many shall come in My name, clothed outwardly in sheep’s clothing, but inwardly they are ravening wolves.” (Mat_7:15) And, ‘There shall be schisms and heresies.’ (1Co_11:19)"Justin Martyr
Dialogue to Trypho Ch. XXXV, Vol.1

"But some most worthless persons are in the habit of carrying about the name [of Jesus Christ] in wicked guile, while yet they practice things unworthy of God, and hold opinions contrary to the doctrine of Christ, to their own destruction, and that of those who give credit to them, whom you must avoid as ye would wild beasts. For “the righteous man who avoids them is saved for ever; but the destruction of the ungodly is sudden, and a subject of rejoicing.” (Pro_10:25, Pro_11:3)"Ignatius (Disciple of Apostle John)
Epistle to Ephesians Bk. 2 Ch. VII, Vol. 1

"And every prophet who teacheth the truth, if he do not what he teacheth, is a false prophet. And every prophet, proved true, working unto the mystery of the Church in the world, yet not teaching others to do what he himself doeth, shall not be judged among you, for with God he hath his judgment; for so did also the ancient prophets. But whoever saith in the Spirit, give me money, or something else, ye shall not listen to him; but if he saith to you to give for others’ sake who are in need, let no one judge him."Teachings of the 12 Apostles
Ch. XI, Vol. 7

(Now these heretics) have themselves been sent forth by Satan, for the purpose of slandering before the Gentiles the divine name of the Church. (And the devil’s object is,) that men hearing, now after one fashion and now after another, the doctrines of those (heretics), and thinking that all of us are people of the same stamp, may turn away their ears from the preaching of the truth, or that they also, looking, (without abjuring,) upon all the tenets of those (heretics), may speak hurtfully of us.Hippolytus
Refutation Bk. VII Ch. XX, Vol. V

“These,” says he, “are the faithful, and he who sits on the chair is a false prophet, ruining the minds of the servants of God. It is the doubters, not the faithful, that he ruins. These doubters then go to him as to a soothsayer, and inquire of him what will happen to them; and he, the false prophet, not having the power of a Divine Spirit in him, answers them according to their inquiries, and according to their wicked desires, and fills their souls with expectations, according to their own wishes. For being himself empty, he gives empty answers to empty inquirers; for every answer is made to the emptiness of man. Some true words he does occasionally utter; for the devil fills him with his own spirit, in the hope that he may be able to overcome some of the righteous.Hermas
The Pastor Book II Commandment Eleven Vol. 2

"He rebuked the ways of those who either attempted to speak lies, or were moved by the spirit of the adversary; and that God often employed the wicked for prophecy and the performance of wonders."Constitution of the Apostles
Bk. 8 Pt. 1 Ch. III, Vol. 7

"And this person was carried away in spirit; and suddenly being seized with a kind of frenzy and ecstasy, he raved, and began to speak and to utter strange things, and to prophesy in a manner contrary to the custom of the Church, as handed down from early times and preserved thenceforward in a continuous succession. And among those who were present on that occasion, and heard those spurious utterances, there were some who were indignant, and rebuked him as one frenzied, and under the power of demons, and possessed by the spirit of delusion, and agitating the multitude, and debarred him from speaking anymore; for they were mindful of the Lord’s distinction and threatening, whereby He warned them to be on their guard vigilantly against the coming of the false prophets."Asterius Urbanus
Extra Writings Ch. II, Vol. 7

And the heretics, indeed, who bring strange fire to the altar of God — namely, strange doctrines — shall be burned up by the fire from heaven, as were Nadab and Abiud. (Lev_10:1, Lev_10:2) But such as rise up in opposition to the truth, and exhort others against the Church of God, [shall] remain among those in hell (apud inferos), being swallowed up by an earthquake, even as those who were with Korah, Dathan, and Abiron. (Num_16:33) But those who cleave asunder, and separate the unity of the Church, [shall] receive from God the same punishment as Jeroboam did. (1Ki_14:10)Irenaeus
Against Heresies Book 4 Vol. 1

"Whosoever, “being waxen fat,” (Deu_32:15) and “become gross,” sets at naught His doctrine, shall go into hell. In like manner, every one that has received from God the power of distinguishing, and yet follows an unskillful shepherd, and receives a false opinion for the truth, shall be punished. “What communion hath light with darkness? or Christ with Belial? Or what portion hath he that believeth with an infidel? or the temple of God with idols?” (2Co_6:14-16) And in like manner say I, what communion hath truth with falsehood? or righteousness with unrighteousness? or true doctrine with that which is false?"Ignatius (Disciple of Apostle John)
Epistle to Ephesians Bk. 2 Ch. XVI, Vol. 1

"The false prophets, who are filled with the lying unclean spirit, neither have done nor do, but venture to work certain wonderful deeds for the purpose of astonishing men, and glorify the spirits and demons of error. But pray that, above all things, the gates of light may be opened to you; for these things, cannot be perceived or understood by all, but only by the man to whom God and His Christ have imparted wisdom.’"Justin Martyr
Dialogue with Trypho Ch. VII, Vol. 1

"Then engaging, for the second time, in certain invocations, so as to astound his deluded victim, he says to her,” Open thy mouth, speak whatsoever occurs to thee, and thou shalt prophesy.” She then, vainly puffed up and elated by these words, and greatly excited in soul by the expectation that it is herself who is to prophesy, her heart beating violently [from emotion], reaches the requisite pitch of audacity, and idly as well as impudently utters some nonsense as it happens. to occur to her, such as might be expected from one heated by an empty spirit. (Referring to this, one superior to me has observed, that the soul is both audacious and impudent when heated with empty air.) Henceforth she reckons herself a prophetess, and expresses her thanks to Marcus for having imparted to her of his own Charis (grace). She then makes the effort to reward him, not only by the gift of her possessions (in which way he has collected a very large fortune), but also by yielding up to him her person, desiring in every way to be united to him, that she may become altogether one with him."Iranaeus
Against Heresies Bk 1. Ch. XIII, Vol. 1

"For that which commands is greater and of higher authority than that which is commanded, inasmuch as the former rules, while the latter is in a state of subjection. If, then, Marcus, or anyone else, does command, — as these are accustomed continually at their feasts to play at drawing lots, and [in accordance with the lot] to command one another to prophesy, giving forth as oracles what is in harmony with their own desires, — it will follow that he who commands is greater and of higher authority than the prophetic spirit, though he is but a man, which is impossible. But such spirits as are commanded by these men, and speak when they desire it, are earthly and weak, audacious and impudent, sent forth by Satan for the seduction and perdition of those who do not hold fast that well-compacted faith which they received at first through the Church."Iranaeus
Against Heresies Bk. 1 Ch. XIII, Vol. 1

"And, ‘Many false Christ’s and false apostles shall arise, and shall deceive many of the faithful.’ (Mat_24:11) There are, therefore, and there were many, my friends, who, coming forward in the name of Jesus, taught both to speak and act impious and blasphemous things; and these are called by us after the name of the men from whom each doctrine and opinion had its origin. (For some in one way, others in another, teach to blaspheme the Maker of all things, and Christ, who was foretold by Him as coming, and the God of Abraham, and of Isaac, and of Jacob, with whom we have nothing in common, since we know them to be atheists, impious, unrighteous, and sinful, and confessors of Jesus in name only, instead of worshippers of Him. Yet they style themselves Christians, just as certain among the Gentiles inscribe the name of God upon the works of their own hands, and partake in nefarious and impious rites.)"Justin Martyr
Dialogue to Trypho Ch. XXXV, Vol.1

"Whosoever, therefore, cometh and teacheth you all these things that have been said before, receive him. But if the teacher himself turn and teach another doctrine to the destruction of this, hear him not; but if he teaches so as to increase righteousness and the knowledge of the Lord, receive him as the Lord"Teachings of the 12 Apostles
