3 But with respect to what you have said, that priests should be lowly, because both the Lord and His apostles were lowly; both all the brethren and Gentiles also well know and love my humility; and you also knew and loved it while you were still in the Church, and were in communion with me. But which of us is far from humility: I, who daily serve the brethren, and kindly receive with good-will and gladness every one that comes to the Church; or you, who appoint yourself bishop of a bishop, and judge of a judge, given for the time by God?
Although the Lord God says in Deuteronomy, “And the man that will do presumptuously, and will not hearken unto the priests or unto the judge who shall be in those days, even that man shall die; and all the people, when they hear, shall fear, and do no more presumptuously.” And again He speaks to Samuel, and says, “They have not despised you, but they have despised me.” And moreover the Lord, in the Gospel, when it was said to Him, “Do you answer the high priest so?”guarding the priestly dignity, and teaching that it ought to be maintained, would say nothing against the high priest, but only clearing His own innocence, answered, saying, “If I have spoken evil, bear witness of the evil; but if well, why do you smite me?” The blessed apostle also, when it was said to him, “Do you revile God's high priest?”spoke nothing reproachfully against the priest, when he might have lifted up himself boldly against those who had crucified the Lord, and who had already sacrificed God and Christ, and the temple and the priesthood; but even although in false and degraded priests, considering still the mere empty shadow of the priestly name, he said, “I knew not, brethren, that he was the high priest; for it is written, You shall not speak evil of the ruler of your people.”
