20 That we may live then securely, the sources of our existence have been made common. On the other hand, to the end that we may have an opportunity of gaining crowns and good report, property has not been made common; in order that hating covetousness, and following after righteousness, and freely bestowing our goods upon the poor, we may by this method obtain a certain kind of relief for our sins. God has made you rich, why makest you yourself poor? He has made you rich that you may assist the needy; that you may have release of your own sins, by liberality to others.
He has given you money, not that you may shut it up for your destruction, but that you may pour it forth for your salvation. For this reason also He has made the possession of riches uncertain and unstable, that by this means he might slack the intensity of your madness concerning it. For if its possessors, even now while they can have no confidence in regard to it, but behold a multitude of snares produced from this quarter, are so inflamed with the desire of these things; if the elements of security and stability were added to wealth, whom would they have spared? From whom would they have refrained? From what widows? From what orphans? From what poor?
