10 But do you wish to take vengeance on those who have annoyed you? This, as I was saying just now, is the very reason why wealth ought specially to be avoided. For it prepares you to thrust the sword against yourself, and renders you liable to a heavier account in the future day of reckoning, and makes your punishment intolerable. For revenge is so great an evil that it actually revokes the mercy of God, and cancels the forgiveness of countless sins which has been already bestowed.
For he who received remission of the debt of ten thousand talents, and after having obtained so great a boon by merely asking for it then made a demand of one hundred pence from his fellow servant, a demand, that is, for satisfaction for his transgression against himself, in his severity towards his fellow servant recorded his own condemnation; and for this reason and no other he was delivered to the tormentors, and racked, and required to pay back the ten thousand talents; and he was not allowed the benefit of any excuse or defence, but suffered the most extreme penalty, having been commanded to deposit the whole debt which the lovingkindness of God had formerly remitted. Is this then the reason, pray, why wealth is so earnestly pursued by you, because it so easily conducts you into sin of this kind?
Nay verily, this is why you ought to abhor it as a foe and an adversary teeming with countless murders. But poverty, some one will say, disposes men to be discontented and often also to utter profane words, and condescend to mean actions. It is not poverty which does this, but littleness of soul: for Lazarus also was poor, aye! very poor: and besides poverty he suffered from infirmity, a bitterer trial than any form of poverty, and one which makes poverty more severely felt; and in addition to infirmity there was a total absence of protectors, and difficulty in finding any to supply his wants, which increased the bitterness of poverty and infirmity.
For each of these things is painful in itself, but when there are none to minister to the sufferer's wants, the suffering becomes greater, the flame more painful, the distress more bitter, the tempest fiercer, the billows stronger, the furnace hotter. And if one examines the case thoroughly there was yet a fourth trial besides these— the unconcern and luxury of the rich man who dwelt hard by. And if you would find a fifth thing, serving as fuel to the flame, you will see quite clearly that he was beset by it.
For not only was that rich man living luxuriously, but twice, and thrice, or rather indeed several times in the day he saw the poor man: for he had been laid at his gate, being a grievous spectacle of pitiable distress, and the bare sight of him was sufficient to soften even a heart of stone: and yet even this did not induce that unmerciful man to assist this case of poverty: but he had his luxurious table spread, and goblets wreathed with flowers, and pure wine plentifully poured forth, and grand armies of cooks, and parasites, and flatterers from early dawn, and troops of singers, cupbearers, and jesters; and he spent all his time in devising every species of dissipation, and drunkenness, and surfeiting, and in revelling in dress and feasting and many other things.
But although he saw that poor man every day distressed by grievous hunger and the bitterest infirmity, and the oppression of his many sores, and by destitution, and the ills which result from these things, he never even gave him a thought: yet the parasites and the flatterers were pampered even beyond their need; but the poor man, and he so very poor, and encompassed with so many miseries, was not even vouchsafed the crumbs which fell from that table, although he greatly desired them: and yet none of these things injured him, he did not give vent to a bitter word, he did not utter a profane speech; but like a piece of gold which shines all the more brilliantly when it is purified by excessive heat, even so he, although oppressed by these sufferings, was superior to all of them, and to the agitation which in many cases is produced by them.
For if generally speaking poor men, when they see rich men, are consumed with envy and racked by malicious ill-will, and deem life not worth living, and this even when they are well supplied with necessary food, and have persons to minister to their wants; what would the condition of this poor man have been had he not been very wise and noble hearted, seeing that he was poor beyond all other poor men, and not only poor, but also infirm, and without any one to protect or cheer him, and lay in the midst of the city as if in a remote desert, and wasted away with bitter hunger, and saw all good things being poured upon the rich man as out of a fountain, and had not the benefit of any human consolation, but lay exposed as a perpetual meal for the tongues of the dogs, for he was so enfeebled and broken down in body that he could not scare them away?
Do you perceive that he who does not injure himself suffers no evil? For I will again take up the same argument.
