Origen, on Acts 20:29

“I know that, after my departure, ravening wolves will enter in among you, not sparing the flock.”

“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.”
