Numbers 16:26

3. Nor let the people flatter themselves that they can be free from the contagion of sin, while communicating with a priest who is a sinner, and yielding their consent to the unjust and unlawful episcopacy of their overseer, when the divine reproof by Hosea the prophet threatens, and says, “Their sacrifices shall be as the bread of mourning; all that eat thereof shall be polluted;” teaching manifestly and showing that all are absolutely bound to the sin who have been contaminated by the sacrifice of a profane and unrighteous priest. Which, moreover, we find to be manifested also in Numbers, when Korah, and Dathan, and Abiram claimed for themselves the power of sacrificing in opposition to Aaron the priest. …

9. And, moreover, that it may be better understood what is the divine judgment against audacity of the like kind, we find that in such wickedness, not only the leaders and originators, but also the partakers, are destined to punishment, unless they have separated themselves from the communion of the wicked; as the Lord by Moses commands, and says, “Separate yourselves from the tents of these most hardened men, and touch nothing of theirs, lest ye be consumed in their sins.” And what the Lord had threatened by Moses He fulfilled, that whosoever had not separated himself from Korah, and Dathan, and Abiram, immediately suffered punishment for his impious communion. …

I mean these remarks for those who give themselves up indiscriminately to the men who are dividing the Church. For if on the one hand those men have doctrines also contrary to ours, then on that account further it is not right to mix with them: if, on the other hand, they hold the same opinions, the reason for not mixing with them is greater still. And why so? Because then the disease is from lust of authority. Know ye not what was the fate of Korah, Dathan, and Abiram? ( Num. xvi. 1-35 .) Of them only did I say? Was it not also of them that were with them? What wilt thou say? Shall it be said, “Their faith is the same, they are orthodox as well as we”? If so, why then are they not with us? There is “one Lord, one faith, one baptism.” If their cause is right, then is ours wrong; if ours is right, then is theirs wrong. …

5. L. Pray, have you not read what is said concerning the bishops,“Ye are the salt of the earth: but if the salt have lost its savour, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out and trodden under foot of man.” And then there is the fact that the priest intercedes with God for the sinful people, while there is no one to entreat for the priest. Now these two passages of Scripture tend to the same conclusion. For as salt seasons all food and nothing is so pleasant as to please the palate without it: so the bishop is the seasoning of the whole world and of his own Church, and if he lose his savour through the denial of truth, or through heresy, or lust, or, to comprehend all in one word, through sin of any kind, by what other can he be seasoned, when he was the seasoning of all? The priest, we know, offers his oblation for the layman, lays his hand u …
