Titus 3:11

On this point, however, we dwell no longer, since it is the same Paul who, in his Epistle to the Galatians, counts “heresies” among “the sins of the flesh,” who also intimates to Titus, that “a man who is a heretic” must be “rejected after the first admonition,” on the ground that “he that is such is perverted, and committeth sin, as a self-condemned man.” Indeed, in almost every epistle, when enjoining on us (the duty) of avoiding false doctrines, he sharply condemns heresies. Of these the practical effects are false doctrines, called in Greek heresies , a word used in the sense of that choice which a man makes when he either teaches them (to others) or takes up with them (for himself). For this reason it is that he calls the heretic self-condemned , because he has himself chosen that for which he is condemned. …

In the next place, that he may have the appearance of knowing still more than he has yet mentioned, he says, agreeably to his usual custom, that “there are others who have wickedly invented some being as their teacher and demon, and who wallow about in a great darkness, more unholy and accursed than that of the companions of the Egyptian Antinous.” And he seems to me, indeed, in touching on these matters, to say with a certain degree of truth, that there are certain others who have wickedly invented another demon, and who have found him to be their lord, as they wallow about in the great darkness of their ignorance. With respect, however, to Antinous, who is compared with our Jesus, we shall not repeat what we have already said in the preceding pages. …

21. But for the rest, let our most beloved brethren firmly decline, and avoid the words and conversations of those whose word creeps onwards like a cancer; as the apostle says, “Evil communications corrupt good manners.” And again: “A man that is an heretic, after one admonition, reject: knowing that he that is such is subverted, and sinneth, being condemned of himself.” And the Holy Spirit speaks by Solomon, saying, “A perverse man carrieth perdition in his mouth; and in his lips he hideth a fire.” Also again, he warneth us, and says, “Hedge in thy ears with thorns, and hearken not to a wicked tongue.” And again: “A wicked doer giveth heed to the tongue of the unjust; but a righteous man does not listen to lying lips.” And although I know that our brotherhood there, assuredly fortified by your foresight, and besides sufficiently cautious by their own vigilance, cannot be taken nor decei …

2. He forbade one coming from any heresy to be baptized in the Church; that is, he judged the baptism of all heretics to be just and lawful. And although special heresies have special baptisms and different sins, he, holding communion with the baptism of all, gathered up the sins of all, heaped together into his own bosom. And he charged that nothing should be innovated except what had been handed down; as if he were an innovator, who, holding the unity, claims for the one Church one baptism; and not manifestly he who, forgetful of unity, adopts the lies and the contagions of a profane washing. Let nothing be innovated, says he, nothing maintained , except what has been handed down. …

To Titus: “A man that is an heretic, after one rebuke avoid; knowing that one of such sort is perverted, and sinneth, and is by his own self condemned.” Of this same thing in the Epistle of John: “They went out from among us, but they were not of us; for if they had been of us, they would doubtless have remained with us.” Also in the second to Timothy: “Their word doth creep as a canker.”

1. The Apostle Paul hath said: “A man that is an heretic after the first and second admonition reject, knowing that he that is such is subverted and sinneth, being condemned of himself.” But though the doctrine which men hold be false and perverse, if they do not maintain it with passionate obstinacy, especially when they have not devised it by the rashness of their own presumption, but have accepted it from parents who had been misguided and had fallen into error, and if they are with anxiety seeking the truth, and are prepared to be set right when they have found it, such men are not to be counted heretics. Were it not that I believe you to be such, perhaps I would not write to you. …

32. But it will be urged that it is written of heretics that "they are condemned of themselves." What then? are they not also condemned of themselves to whom it was said, "For wherein thou judgest another, thou condemnest thyself?" But to these the apostle says, "Thou that preachest a man should not steal, dost thou steal?" and so forth. And such truly were they who, being bishops and established in Catholic unity with Cyprian himself, used to plunder estates by treacherous frauds, preaching all the time to the people the words of the apostle, who says, "Nor shall extortioners inherit the kingdom of God."

Titus iii. 8-11 “These things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men. But avoid foolish questions, and genealogies, and contentions, and strivings about the law, for they are unprofitable and vain. A man that is an heretic after the first and second admonition reject. Knowing that he that is such is subverted, and sinneth, being condemned of himself.”

7. And Polycarp himself, when Marcion once met him and said, ‘Knowest thou us?’ replied, ‘I know the first born of Satan.’ Such caution did the apostles and their disciples exercise that they might not even converse with any of those who perverted the truth; as Paul also said, ‘A man that is a heretic, after the first and second admonition, reject; knowing he that is such is subverted, and sinneth, being condemned of himself.’

2. You, however, beloved and most truly longed-for, have done what befitted the tradition of the Church and your piety toward the Lord, in refuting, admonishing, and rebuking such men. But since, instigated by their father the devil, ‘they knew not nor understood,’ as it is written, ‘but go on still in darkness,’ let them learn from your piety that this error of theirs belongs to Valentinus and Marcion, and to Manichæus, of whom some substituted [the idea of] Appearance for Reality, while the others, dividing what is indivisible, denied the truth that ‘the Word was made Flesh, and dwelt among us.’ Why then, as they hold with those people, do they not also take up the heritage of their names? For it is reasonable, as they hold their error, to have their names as well, and for the future to be called Valentinians, Marcionists, and Manichæans. …

Having read the letter now come from you, I approve your piety: but, marvelling at the rashness of those ‘who understand neither what they say nor whereof they confidently affirm,’ I had really decided to say nothing. For to reply upon matters which are so plain and which are clearer than light, is simply to give an excuse for shamelessness to such lawless men. And this we have learned from the Saviour. For when Pilate had washed his hands, and acquiesced in the false accusation of the Jews of that day, the Lord answered him no more, but rather warned his wife in a dream, so that He that was being judged might be believed to be God not in word, but in power. While after vouchsafing Caiaphas no reply to his folly, He Himself by his promise brought all over to knowledge. …

The apostle bears witness that contention has never done good in the church; and for this reason he gives direction that heretics should be admonished once or twice in the beginning of their heresy and not subjected to a long series of rebukes. Where this rule is negligently observed, the evil to be guarded against so far from being evaded is rather intensified.
