Apostolic Constitutions : But when we went forth among the Gentiles to preach the word of life, then the devil wrought in the people to send after us false apostles to the corrupting of the word; and they sent forth one Cleobius, and joined him with Simon, and these became disciples to one Dositheus, whom they despising, put him down from the principality. Afterwards also others were the authors of absurd doctrines: Cerinthus, and Marcus, and Menander, and Basilides, and Saturnilus. Of these some own the doctrine of many gods, some only of three, but contrary to each other, without beginning, and ever with one another, and some of an infinite number of them, and those unknown ones also. And some reject marriage; and their doctrine is, that it is not the appointment of God; and others abhor some kinds of food: some are impudent in uncleanness, such as those who are falsely called Nicolaitans... — Constitutions of the Holy Apostles Book 6 Clement of Alexandria : I have quoted these remarks to prove in error those Basilidians who do not live purely, supposing either that they have the power even to commit sin because of their perfection, or indeed that they will be saved by nature even if they sin in this life because they possess an innate election. For the original teachers of their doctrines do not allow one to do the same as they are now doing. They ought not, therefore, to take as a covering cloak the name of Christ and, by living lewder lives than the most uncontrolled heathen, bring blasphemy upon his name. "For such people are false apostles, deceitful workers" as far as the words "whose end shall be like their works." — The Stromata Book 3 John Chrysostom : What sayest thou? they that preach Christ, they that take not money, they that bring not in a different gospel, "false apostles?" 'Yes,' he saith, and for this very reason most of all, because they make pretense of all these things for the purpose of deceiving. "Deceitful workers," for they do work indeed, but pull up what has been planted. For being well aware that otherwise they would not be well received, they take the mask of truth and so enact the drama of error. 'And yet,' saith one, 'they take no money.' That they may take greater things; that they may destroy the soul. Yea rather, even that was a falsehood; and they took money but did it secretly: and he shows this in what follows. And indeed he already hinted this where he said, "that wherein they glory, they may be found even as we:" in what follows, however, he hinted it more plainly, saying, "If a man devour you, if a man take you captive, if a man exalt himself, ye bear with him." But at present he accuses them on another account, saying, "fashioning themselves." They had only a "fashion;" the skin of the sheep was but outside clothing. — Homily 24 on 2 Corinthians Pseudo-Clement : Beloved brethren! That a man should build up and establish the brethren on the faith in one God, this also is manifest and well-known. This too, again, is comely, that a man should not be envious of his neighbour. And moreover, again, it is suitable and comely that all those who work the works of the Lord should work the works of the Lord in the fear of God. Thus is it required of them to conduct themselves. That "the harvest is great, but the workmen are few," this also is well-known and manifest. Let us, therefore, "ask of the Lord of the harvest" that He would send forth workmen into the harvest; [Matthew 9:37-38] such workmen as "shall skilfully dispense the word of truth;" workmen "who shall not be ashamed;" faithful workmen; workmen who shall be "the light of the world;" [Matthew 5:14] workmen who "work not for the food that perishes, but for that food which abides unto life eternal;" [John 6:27] workmen who shall be such as the apostles; workmen who imitate the Father, and the Son, and the Holy Spirit; who are concerned for the salvation of men; not "hireling" [John 10:12-13] workmen; not workmen to whom the fear of God and righteousness appear to be gain; not workmen who "serve their belly;" not workmen who "with fair speeches and pleasant words mislead the hearts of the innocent;" [Romans 16:18] not workmen who imitate the children of light, while they are not light but darkness — "men whose end is destruction;" [Philippians 3:9] not workmen who practise iniquity and wickedness and fraud; not "crafty workmen;" [2 Corinthians 11:13] not workmen "drunken" and "faithless;" nor workmen who traffic in Christ; not misleaders; not "lovers of money; not malevolent." Let us, therefore, contemplate and imitate the faithful who have conducted themselves well in the Lord, as is becoming and suitable to our calling and profession. Thus let us do service before God in justice and righteousness, and without blemish, "occupying ourselves with things good and comely before God and also before men." For this is comely, that God be glorified in us in all things. — Two Epistles on Virginity Tertullian : when he designates "false apostles, deceitful workers transforming themselves" into likenesses of himself, of course by their hypocrisy, he charges them with the guilt of disorderly conversation, rather than of false doctrine. The contrariety, therefore, was one of conduct, not of gods. If "Satan himself, too, is transformed into an angel of light," such an assertion must not be used to the prejudice of the Creator. The Creator is not an angel, but God. Into a god of light, and not an angel of light, must Satan then have been said to be transformed, if he did not mean to call him "the angel," which both we and Marcion know him to be. — Against Marcion Book V
