8 Driven from this line of defence you will appeal to the example of the clergy. These, you will say, remain in their cities, and yet they are surely above criticism. Far be it from me to censure the successors of the apostles, who with holy words consecrate the body of Christ, and who make us Christians. Having the keys of the kingdom of heaven, they judge men to some extent before the day of judgment, and guard the chastity of the bride of Christ. But, as I have before hinted, the case of monks is different from that of the clergy.
The clergy feed Christ's sheep; I as a monk am fed by them. They live of the altar: I, if I bring no gift to it, have the axe laid to my root as to that of a barren tree. Nor can I plead poverty as an excuse, for the Lord in the gospel has praised an aged widow for casting into the treasury the last two coins that she had. I may not sit in the presence of a presbyter; he, if I sin, may deliver me to Satan, “for the destruction of the flesh that the spirit may be saved.” Under the old law he who disobeyed the priests was put outside the camp and stoned by the people, or else he was beheaded and expiated his contempt with his blood. But now the disobedient person is cut down with the spiritual sword, or he is expelled from the church and torn to pieces by ravening demons.
Should the entreaties of your brethren induce you to take orders, I shall rejoice that you are lifted up, and fear lest you may be cast down. You will say: “If a man desire the office of a bishop, he desires a good work.” I know that; but you should add what follows: such an one “must be blameless, the husband of one wife, vigilant, sober, chaste, of good behavior, given to hospitality, apt to teach, not given to wine, no striker but patient.” After fully explaining the qualifications of a bishop the apostle speaks of ministers of the third degree with equal care.
“Likewise must the deacons be grave,” he writes, “not double-tongued, not given to much wine, not greedy of filthy lucre, holding the mystery of the faith in a pure conscience. And let these also first be proved; then, let them minister, being found blameless.” Woe to the man who goes in to the supper without a wedding garment. Nothing remains for him but the stern question, “Friend, how did you come in hither?” And when he is speechless the order will be given, “Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth.” Woe to him who, when he has received a talent, has bound it in a napkin; and, while others make profits, only preserves what he has received.
His angry lord shall rebuke him in a moment. “Thou wicked servant,” he will say, “wherefore gavest thou not my money into the bank that at my coming I might have required my own with usury?” That is to say, you should have laid before the altar what you were not able to bear. For while you, a slothful trader, keep a penny in your hands, you occupy the place of another who might double the money. Wherefore, as he who ministers well purchases to himself a good degree, so he who approaches the cup of the Lord unworthily shall be guilty of the body and blood of the Lord.
