Cyprian : I indeed desire, beloved brethren, and I equally endeavour and exhort, that if it be possible, none of the brethren should perish, and that our rejoicing Mother may enclose in her bosom the one body of a people at agreement. Yet if wholesome counsel cannot recall to the way of salvation certain leaders of schisms and originators of dissensions, who abide in blind and obstinate madness, yet do you others, if either taken in simplicity, or induced by error, or deceived by some craftiness of misleading cunning, loose yourselves from the nets of deceit, free your wandering steps from errors, acknowledge the straight way of the heavenly road. The word of the witnessing apostle is: "We command you," says he, "in the name of our Lord Jesus Christ, that ye withdraw yourselves from all brethren that walk disorderly, and not after the tradition that they have received from us." And again he says, "Let no man deceive you with vain words; for because of these things cometh the wrath of God upon the children of disobedience. Be not ye therefore partakers with them." We must withdraw, nay rather must flee, from those who fall away, lest, while any one is associated with those who walk wickedly, and goes on in ways of error and of sin, he himself also, wandering away from the path of the true road, should be found in like guilt. God is one, and Christ is one, and His Church is one, and the faith is one, and the people is joined into a substantial unity of body by the cement of concord. Unity cannot be severed; nor can one body be separated by a division of its structure, nor torn into pieces, with its entrails wrenched asunder by laceration. Whatever has proceeded from the womb cannot live and breathe in its detached condition, but loses the substance of health. — Treatise I. On the Unity of the Church. Cyprian : Let the lapsed, however, who acknowledge the greatness of their sin, not depart from entreating the Lord, nor forsake the Catholic Church, which has been appointed one and alone by the Lord; but, continuing in their atonements and entreating the Lord's mercy, let them knock at the door of the Church, that they may be received there where once they were, and may return to Christ from whom they have departed, and not listen to those who deceive them with a fallacious and deadly seduction; since it is written, "Let no man deceive you with vain words, for because of these things cometh the wrath of God upon the children of disobedience; be not ye therefore partakers with them." Therefore let no one associate himself with the contumacious, and those who do not fear God, and those who entirely with draw from the Church. But if any one should be impatient of entreating the Lord who is offended, and should be unwilling to obey us, but should follow desperate and abandoned men, he must take the blame to himself when the day of judgment shall come. For how shall he be able in that day to entreat the Lord, who has both before this denied Christ, and now also the Church of Christ, and not obeying bishops sound and wholesome and living, has made himself an associate and a partaker with the dying? I bid you, dearest brethren and longed-for, ever heartily farewell. — Epistle LXIII Cyprian : The Lord warns us in His Gospel, saying, "Ye reject the commandment of God, that ye may establish your own tradition." Let them who reject the commandment of God and endeavour to keep their own tradition be bravely and firmly rejected by you; let one downfall be sufficient for the lapsed; let no one by his fraud hurl down those who wish to rise; let no one cast down more deeply and depress those who are down, on whose behalf we pray that they may be raised up by God's hand and arm; let no one turn away from all hope of safety those who are half alive and entreating that they may receive their former health; let no one extinguish every light of the way of salvation to those that are wavering in the darkness of their lapse. The apostle instructs us, saying, "If any man teach otherwise, and consent not to the wholesome words of our Lord Jesus Christ and His doctrine, he is lifted up with foolishness: from such withdraw thyself." And again he says, "Let no man deceive you with vain words; for because of these things cometh the wrath of God upon the children of disobedience. Be not ye therefore partakers with them." There is no reason that you should be deceived with vain words, and begin to be partakers of their depravity. Depart from such, I entreat you, and acquiesce in our counsels, who daily pour out for you continual prayers to the Lord, who desire that you should be recalled to the Church by the clemency of the Lord, who pray for the fullest peace from God, first for the mother, and then for her children. Join also your petitions and prayers with our prayers and petitions; mingle your tears with our wailings. Avoid the wolves who separate the sheep from the shepherd; avoid the envenomed tongue of the devil, who from the beginning of the world, always deceitful and lying, lies that he may deceive, cajoles that he may injure, promises good that he may give evil, promises life that he may put to death. Now also his words are evident, and his poisons are plain. He promises peace, in order that peace may not possibly be attained; he promises salvation, that he who has sinned may not come to salvation; he promises a Church, when he so contrives that he who believes him may utterly perish apart from the Church. — Epistle XXXIX Gaius Marius Victorinus : These people he calls "children of disobedience"; for there are many who make light of the promise of a heavenly kingdom.… They disbelieve; they have no faith. The wrath of God comes upon the children of disobedience. Disobedience is epitomized by the devil they serve. Therefore they are said to be his children. — EPISTLE TO THE Ephesians 2.5.6 Irenaeus : And just as then, those who led vicious lives, and put other people astray, were condemned and cast out, so also even now the offending eye is plucked out, and the foot and the hand, lest the rest of the body perish in like manner. And we have the precept: "If any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner, with such an one no not to eat." And again does the apostle say, "Let no man deceive you with vain words; for because of these things cometh the wrath of God upon the sons of mistrust. Be not ye therefore partakers with them." And as then the condemnation of sinners extended to others who approved of them, and joined in their society; so also is it the case at present, that "a little leaven leaveneth the whole lump." — Against Heresies Book IV Pseudo-Clement : For virgins are a beautiful pattern to believers, and to those who shall believe. The name alone, indeed, without works, does not introduce into the kingdom of heaven; but, if a man be truly a believer, such an one can be saved. For, if a person be only called a believer in name, whilst he is not such in works, he cannot possibly be a believer. "Let no one," therefore, "lead you astray with the empty words of error." [Ephesians 5:6] For, merely because a person is called a virgin, if he be destitute of works excellent and comely, and suitable to virginity, he cannot possibly be saved. For our Lord called such virginity as that "foolish," as He said in the Gospel; and because it had neither oil nor light, it was left outside of the kingdom of heaven, and was shut out from the joy of the bridegroom, and was reckoned with His enemies. For such persons as these "have the appearance only of the fear of God, but the power of it they deny." For they "think with themselves that they are something, whilst they are nothing, and are deceived. But let every one constantly try his works," and know himself; for empty worship does he offer, whosoever he be that makes profession of virginity and sanctity, "and denies its power." For virginity of such a kind is impure, and disowned by all good works. For "every tree whatsoever is known from its fruits." — Two Epistles on Virginity, Epistle 1
