Augustine of Hippo
Catena Aurea · Lukasevangelium 16
And the lord commended the unjust steward, because he had done wisely: for the children of this world are in their generation wiser than the children of light. And I say unto you, Make to yourselves friends of the mammon of unrighteousness; that, when ye fail, they may receive you into everlasting habitations. He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much. If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true riches? And if ye have not been faithful in that which is another man’s, who shall give you that which is your own? No servant can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
(Serm. 113.) For who are they that shall have everlasting habitations but the saints of God? and who are they that are to be received by them into everlasting habitations but they who administer to their want, and whatsoever they have need of, gladly supply. They are those little ones of Christ, who have forsaken all that belonged to them and followed Him; and whatsoever they had have given to the poor, that they might serve God without earthly shackles, and freeing their shoulders from the burdens of the world, might raise them aloft as with wings.
