Irenaeus of Lyons, Against Heresies 4.26.3

Many believe these men to be presbyters, yet they serve their own desires and have not set the fear of God in their hearts. Instead they treat everyone else with contempt, puffed up with the pride of preeminence, and they do evil in secret while saying, "No one sees us." The Word will convict them, for he does not judge by outward appearance or show partiality, but looks on the heart. You will hear these voices from the prophet Daniel: "Seed of Canaan and not of Judah, desire has deceived you, and lust has overturned your heart. Old man of evil days, now your sins which you committed before have come upon you — judging unjust judgments, condemning the innocent, and acquitting the guilty — while the Lord says, 'You shall not kill the innocent and the just.'" Concerning such men the Lord also said: "But if that evil servant says in his heart, 'My master is delayed,' and begins to beat the menservants and maidservants, and to eat and drink and get drunk, the master of that servant will come on a day he does not expect and at an hour he does not know, and will cut him in pieces and assign his portion with the faithless."
