9 Why should any one speak of the injuries that result from grief, the insults, the abuse, the censure from superiors, from inferiors, from the wise, and from fools; for the class who are wanting in right judgment are particularly fond of censuring, and will never readily allow any excuse. But the truly excellent Bishop ought neither to think lightly of these, but to clear himself with all men of the charges which they bring against him, with great forbearance and meekness, pardoning their unreasonable fault-finding, rather than being indignant and angry about it.
For if St. Paul feared lest he should incur a suspicion of theft, among his disciples, and therefore procured others for the management of the money, that “no one” he says, “should blame us in this abundance which is administered by us,” how ought we not to do all so as to remove evil suspicions, even if they happen to be false, and most unreasonable, and very foreign to our thought? For we are not so utterly removed from any sin as St. Paul from theft; notwithstanding, though so far from this evil practice, he did not, therefore, slight the suspicion of the world, although it was very absurd, and even insane.
For it was madness to have any such suspicion about that blessed and admirable character. But none the less does he remove far off the causes of this suspicion, unreasonable though it was, and such as no one who was in his senses would entertain, and he neither disdained the folly of the multitudes, nor did he say, “To whose mind did it ever occur to suspect such things of us, after the signs which I have wrought, and the forbearance which has marked my life, and when you all revered and admired us?”
Quite the contrary: he foresaw and expected this base suspicion, and pulled it up by the roots, or rather did not suffer it to grow at all. Why? “Because,” says he, “we provide things honest not only before the Lord, but before all men.” So great, yea and far greater zeal must we use, to uproot and prevent floating reports which are not good, but to see beforehand from afar whence they come, and to remove beforehand the causes from which they are produced, not to wait till they are established and are the common topics in every one's mouth.
For then it is not easy in the future to destroy them, but very difficult, perhaps impossible, and not without mischief, because this is done after many have been injured. But how far shall I continue pursuing the unattainable? For to enumerate all the difficulties in this direction, is nothing more nor less than measuring the ocean. Even when any one should clear himself from every passion (which is a thing impossible) in order to correct the failings of others, he is forced to undergo countless trials, and when his own infirmities are added, behold, an abyss of toil and care, and all that he must suffer, who wishes to subdue the evils in himself and in those around him.
