What labors were it worth to us to discover such a remedy. For say, were there not the relief of almsgiving, while we still by our numberless sins rendered ourselves liable to Divine vengeance, should we not have lamented sadly? Should we not have said, O that it were possible by our wealth to wash away our sins, and we would have parted with it all! O that by our riches we could put away the wrath of God, then we would not spare our substance? For if we do this in sickness, and at the point of death we say, “If it were possible to buy off death, such an one would give all his possessions”; much more in this matter. For see how great is the love of God for man. He has granted us power to buy off not temporal but eternal death. Do not purchase, He says, this short life, but that life that is everlasting. It is that I sell you, not the other: I do not mock you. Did you gain the present life, you had gained nothing. I know the worth of that which I offer you. The bargainers and traffickers in worldly goods do not act thus. They, when they can impose on whom they will, give a little to receive a great deal. It is not so with God. He gives the greater by far for the less.
Tell me, if you were to go to a merchant, and he were to set before you two stones, one of little worth, and the other very precious, and sure to fetch a large amount of wealth; if he allowed you for the price of the cheap one to carry off the more costly, should you complain of him? No! You would rather admire his liberality. So now, two lives are set before us, the one temporal, the other eternal. These God offers us for sale, but He would sell us the latter rather than the former. Why do we complain, like silly children, that we receive the more precious? Is it possible then to purchase life for money? Yes, when what we bestow is our own, and not the property of another; when we do not practice an imposture. But, you say, henceforth the goods are mine. They are not yours after rapine. They are still your neighbor's, though thou were a thousand times the master of them. For if you should receive a deposit, it would not be your own even for the short season that the depositor was traveling, though it might be laid up with you. If therefore that is not ours, which we received with the consent and thanks of those who deposited it, even for the short period that we retain it, much less is that ours, which we plundered against the will of its owner. He is the master of it, however long you may withhold it. But Virtue is really our own; as for money, even our own is not strictly ours, much less that of others. Today it is ours, tomorrow it belongs to another. What is of virtue is our own possession. This does not suffer loss, like other things, but is entirely possessed by all who have it. This therefore let us acquire, and let us despise riches, that we may be able to attain those real goods, of which God grant that we may be thought worthy to partake, through the grace and lovingkindness, etc.
