4 What then? Some one will say, did he not inflict injury on Adam, and upset him, and cast him out of paradise? No: he did it not, but the cause was the listlessness of him who was injured, and his want of temperance and vigilance. For he who applied such powerful and manifold devices and yet was not able to subdue Job, how could he by inferior means have mastered Adam, had not Adam betrayed himself through his own listlessness? What then? Has not he been injured who has been exposed to slander, and suffered confiscation of his property, having been deprived of all his goods, and is thrown out of his patrimony, and struggles with extreme poverty?
No! He has not been injured, but has even profited, if he be sober. For, tell me, what harm did this do the apostles? Were they not continually struggling with hunger, and thirst and nakedness? And this was the very reason why they were so illustrious, and distinguished, and won for themselves much help from God. Again what harm was done to Lazarus by his disease, and sores, and poverty and dearth of protectors? Were they not the reasons why garlands of victory were more abundantly woven for him?
Or what harm was done to Joseph by his getting evil reported of, both in his own land, and in the land of strangers for he was supposed to be both an adulterer and fornicator: or what harm did servitude do him or expatriation? Is it not specially on account of these things that we regard him with admiration and astonishment? And why do I speak of removal into a foreign land, and poverty, and evil report, and bondage? For what harm did death itself inflict on Abel, although it was a violent and untimely death, and perpetrated by a brother's hand?
Is not this the reason why his praise is sounded throughout the whole world? Do you see how the discourse has demonstrated even more than it promised? For not only has it disclosed the fact that no one is injured by anybody, but also that they who take heed to themselves derive the greater gain (from such assaults). What is the purpose then it will be said of penalties and punishments? What is the purpose of hell? What is the purpose of such great threatenings, if no one is either injured or injures?
What is it you say? Why do you confuse the argument? For I did not say that no one injures, but that no one is injured. And how is it possible, you will say, for no one to be injured when many are committing injury? In the way which I indicated just now. For Joseph's brethren did indeed injure him, yet he himself was not injured: and Cain laid snares for Abel, yet he himself was not ensnared. This is the reason why there are penalties and punishments. For God does not abolish penalties on account of the virtue of those who suffer; but he ordains punishments on account of the malice of those who do wickedly.
For although they who are evil entreated become more illustrious in consequence of the designs formed against them, this is not due to the intention of those who plan the designs, but to the courage of those who are the victims of them. Wherefore for the latter the rewards of philosophy are made ready and prepared, for the former the penalties of wickedness. Have you been deprived of your money? Read the word “Naked came I out of my mother's womb, and naked shall I return there.” And add to this the apostolic saying “for we brought nothing into this world; it is certain we can carry nothing out.” Are you evil reported of, and have some men loaded you with countless abuse?
Remember that passage where it is said “Woe unto you when all men shall speak well of you” and “rejoice ye and leap for joy when they shall cast upon you an evil name.” Have you been transported into the land of exile? Consider that you have not here a fatherland, but that if you will be wise you are bidden to regard the whole world as a strange country. Or have you been given over to a sore disease? Quote the apostolic saying “the more our outward man decays, so much the more is the inward man renewed day by day.” Has any one suffered a violent death?
Consider the case of John, his head cut off in prison, carried in a charger, and made the reward of a harlot's dancing. Consider the recompense which is derived from these things: for all these sufferings when they are unjustly inflicted by any one on another, expiate sins, and work righteousness. So great is the advantage of them in the case of those who bear them bravely.
