But again, if one is a man of violence, is this a matter of necessity? Yes, he will say, because his passion carries him away, and burns within him, and does not let the soul be at rest. Man, to act with violence is not the effect of anger, but of littleness of mind. Were it the effect of anger, all men, whenever they were angry, would never cease committing acts of violence. We have anger given us, not that we may commit acts of violence on our neighbors, but that we may correct those that are in sin, that we may bestir ourselves, that we may not be sluggish. Anger is implanted in us as a sort of sting, to make us gnash with our teeth against the devil, to make us vehement against him, not to set us in array against each other. We have arms, not to make us at war among ourselves, but that we may employ our whole armor against the enemy. Are you prone to anger? Be so against your own sins: chastise your soul, scourge your conscience, be a severe judge, and merciless in your sentence against your own sins. This is the way to turn anger to account. It was for this that God implanted it within us.
But again, is plunder a matter of necessity? No, in no wise. Tell me, what manner of necessity is there to be grasping: what manner of compulsion? Poverty, a man will say, causes it, and the fear of being without common necessaries. Now this is the very reason why you ought not to be grasping. Wealth so gotten has no security in it. You are doing the very same thing as a man would do, who, if he were asked why he laid the foundation of his house in the sand, should say, he did it because of the frost and rain. Whereas this would be the very reason why he should not lay it in the sand. They are the very foundations which the rain, and blasts, and wind, most quickly overturn. So that if you would be wealthy, never be rapacious; if you would transmit wealth to your children, get righteous wealth, at least, if any there be that is such. Because this abides, and remains firm, whereas that which is not such, quickly wastes and perishes. Tell me, have you a mind to be rich, and do you take the goods of others? Surely this is not wealth: wealth consists in possessing what is your own. He that is in possession of the goods of others, never can be a wealthy man; since at that rate even your very silk venders, who receive their goods as a consignment from others, would be the wealthiest and the richest of men. Though for the time, indeed, it is theirs, still we do not call them wealthy. And why forsooth? Because they are in possession of what belongs to others. For though the piece itself happens to be theirs, still the money it is worth is not theirs. Nay, and even if the money is in their hands, still this is not wealth. Now, if consignments thus given render not men more wealthy because we so soon resign them, how can those which arise from rapine render them wealthy? However, if at any rate you desire to be wealthy, (for the matter is not one of necessity,) what greater good is it that you would fain enjoy? Is it a longer life? Yet, surely men of this character quickly become short-lived. Oftentimes they pay as the penalty of plunder and rapaciousness, an untimely death; and not only suffer as a penalty the loss of the enjoyment of their gains, but go out of life having gained but little, and hell to boot. Oftentimes too they die of diseases, which are the fruits of self-indulgence, and of toil, and of anxiety. Fain would I understand why it is that wealth is so eagerly pursued by mankind. Why surely for this reason has God set a limit and a boundary to our nature, that we may have no need to go on seeking wealth beyond it. For instance He has commanded us, to clothe the body in one, or perhaps in two garments; and there is no need of any more to cover us. Where is the good of ten thousand changes of raiment, and those moth-eaten? The stomach has its appointed bound, and any thing given beyond this, will of necessity destroy the whole man. Where then is the use of your herds, and flocks, and cutting up of flesh? We require but one roof to shelter us. Where then is the use of your vast ground-plots, and costly buildings? Do you strip the poor, that vultures and jackdaws may have where to dwell? And what a hell do not these things deserve? Many are frequently raising edifices that glisten with pillars and costly marbles, in places which they never so much as saw. What scheme is there indeed that they have not adopted? Yet neither themselves reap the benefit, nor any one else. The desolateness does not allow them to get away there; and yet not even thus do they desist. You see that these things are not done for profit's-sake, but in all these cases folly, and absurdity, and vainglory, is the motive. And this, I beseech you to avoid, that we may be enabled to avoid also every other evil, and may obtain those good things which are promised to them that love Him, in our Lord Jesus Christ, with whom to the Father, together with the Holy Ghost, be glory, strength, honor forever. Amen.
