Cyprian : These several matters, I pray you, suggest to our brethren. And as "he who humbleth himself shall be exalted," now is the time when they should rather fear the ensnaring adversary, who more eagerly attacks the man that is strongest, and becoming more virulent, for the very reason that he is conquered, strives to overcome his conqueror. The Lord grant that I may soon both see them again, and by salutary exhortation may establish their minds to preserve their glory. For I am grieved when I hear that some of them run about wickedly and proudly, and give themselves up to follies or to discords; that members of Christ, and even members that have confessed Christ, are defiled by unlawful concubinage, and cannot be ruled either by deacons or by presbyters, but cause that, by the wicked and evil characters of a few, the honourable glories of many and good confessors are tarnished; whom they ought to fear, lest, being condemned by their testimony and judgment, they be excluded from their fellowship. That, finally, is the illustrious and true confessor, concerning whom afterwards the Church does not blush, but boasts. — Epistle V John Chrysostom : "For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock." Again he engages them from another quarter, from the things which should come after: as when he says, "We wrestle not against flesh and blood. After my departing," he says, "grievous wolves shall enter in among you" (Eph. vi. 12); twofold the evil, both that he himself would not be present, and that others would assail them. "Then why depart, if thou knowest this beforehand?" The Spirit draws me, he says. Both "wolves," and "grievous, not sparing the flock;" and what is worse, even "from among your own selves:" the grievous thing (this), when the war is moreover an intestine war. The matter is exceeding serious, for it is "the Church of the Lord:" great the peril for with blood He redeemed it: mighty the war, and twofold. "Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them." — Homily on Acts 44 Origen of Alexandria : If you touch "what is seized by a wild beast," you will be unclean. Which wild beast? Is it a lion or a wolf that ravishes persons or animals? I believe that beast is the one about whom the apostle Peter says, "your adversary, the devil, goes around like a roaring lion seeking whom he can devour. Resist him, strong in the faith." And again, the apostle Paul says concerning these, "For after my departure, fierce wolves will come in, not sparing the flock." If you see one made captive by these beasts, do not follow him, do not touch him, lest you also be made unclean. Furthermore, there are also other unclean animals whose carcass it is forbidden to touch. Unclean animals are people who are without Christ, in whom there is neither reason nor anything religious. Therefore, if you see the "carcasses," that is, the sins of all these, the lawgiver tells you not to take hold, not to touch, not to handle. — HOMILIES ON Leviticus 3.3.5
