John Chrysostom
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.
Mark also that He said not, “that they may receive you into their own habitations.” For it is not they who receive you. Therefore when He said, Make to yourselves friends, he added, of the mammon of unrighteousness, to shew, that their friendship will not alone protect us unless good works accompany us, unless we righteously cast away all riches unrighteously amassed. The most skilful then of all arts is that of almsgiving. For it builds not for us houses of mud, but lays up in store an everlasting life. Now in each of the arts one needs the support of another; but when we ought to shew mercy, we need nothing else but the will alone.
