John 10:19
5 And certainly were there not this fear, all would be lost, when though such punishments hang over them, there are many who go over to the side of wickedness. These things if you wisely observe, you will be more ready-minded towards alms-doing, and wilt reap much pleasure, far greater than those who come down from the theater. For they when they remove from thence are inflamed and burn with desire. Having seen those women hovering on the stage, and received from them ten thousand wounds, they will be in no better condition than a tossing sea, when the image of the faces, the gestures, the speeches, the walk, and all the rest, stand before their eyes and besiege their soul. But they who come forth from a prison will suffer nothing of this kind, but will enjoy great calm and tranquillity. For the compunction arising from the sight of the prisoners, quenches all that fire. And if a woman that is an harlot and a wanton meet a man coming forth from among the prisoners, she will work him no mischief. For becoming for the time to come, as it were, incapable of molding, he will thus not be taken by the nets of her countenance, because instead of that wanton countenance there will then be placed before his eyes the fear of the Judgment. On this account, he who had gone over every kind of luxury said, “It is better to go into the house of mourning than into the house of mirth.” And so “here” you will show forth great wisdom, and “there” wilt hear those words which are worth ten thousand blessings. Let us then not neglect such a practice and occupation. For although we be not able to bring them food, nor to help them by giving money, yet shall we be able to comfort them by our words, and to raise up the drooping spirit, and to help them in many other ways by conversing with those who cast them into prison, and by making their keepers kinder, and we certainly shall effect either small or great good. But if you say that the men there are neither men of condition, nor good, nor gentle, but man-slayers, tomb-breakers, cut-purses, adulterers, intemperate, and full of many wickednesses, by this again you show to me a pressing reason for spending time there. For we are not commanded to take pity on the good and to punish the evil, but to manifest this lovingkindness to all men. “Be,” It says, “like to My Father which is in heaven, for He makes His sun to rise on the evil and on the good, and sends rain on the just and on the unjust.” Do not then accuse other men's faults bitterly, nor be a severe judge, but mild and merciful. For we also, if we have not been adulterers, or tomb-breakers, or cut-purses, yet have we other transgressions which deserve infinite punishment. Perchance we have called our brother “fool,” which prepares for us the pit; we have looked on women with unchastened eyes, which constitutes absolute adultery; and what is more grievous than all, we partake not worthily of the Mysteries, which makes us guilty of the Body and Blood of Christ. Let us then not be bitter enquirers into the conduct of others, but consider our own state, so shall we desist from this inhumanity and cruelty. Besides this, it may be said that we shall there find many good men, and often men worth as much as all the city. Since even that prison-house in which Joseph was had in it many evil men, yet that just man had the care of them all, and was, with the rest, concealed as to his real character; for he was worth as much as all the land of Egypt, yet still he dwelt in the prison-house, and no one knew him of those that were within it. Thus also even now it is likely that there are many good and virtuous men, though they be not visible to all men, and the care you take of such as these gives you a return for your exertions in favor of the whole. Or if there be none such, still even in this case great is your recompense; for your Lord conversed not with the just only, while He avoided the unclean, but received with kindness both the Canaanitish woman, and her of Samaria, the abominable and impure; another also who was a harlot, on whose account the Jews reproached Him, He both received and healed, and allowed His feet to be washed by the tears of the polluted one, teaching us to condescend to those that are in sin, for this most of all is kindness. What do you say? Do robbers and tomb-breakers dwell in the prison? And, tell me, are all they just men that dwell in the city? Nay, are there not many worse even than these, robbing with greater shamelessness? For the one sort, if there be no other excuse for them, at least put before themselves the veil of solitude and darkness, and the doing these things clandestinely; but the others throw away the mask and go after their wickedness with uncovered head, being violent, grasping, and covetous. Hard it is to find a man pure from injustice.
6. If we do not take by violence gold, or such and such a number of acres of land, yet we bring about the same end by deceit and robbery in lesser matters, and where we are able to do so. For when in making contracts, or when we must buy or sell anything, we dispute and strive to pay less than the value, and use our utmost endeavors to have it so, is not the action robbery? Is it not theft and covetousness? Tell not me that you have not wrested away houses or slaves, for injustice is judged not by the measure of the things taken, but by the intention of those who commit the robbery. Since “just” and “unjust” have the same force in great and in little things; and I call cut-purses alike the man who cuts through a purse and takes the gold, and him who buying from any of the market people deducts something from the proper price; nor is he the only house-breaker who breaks through a wall and steals anything within, but that man also who corrupts justice, and takes anything from his neighbor.
