Basil the Great
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.
(Hom. de Avar.) Or if thou hast succeeded to a patrimony, thou receivest what has been amassed by the unrighteous; for in a number of predecessors some one must needs be found who has unjustly usurped the property of others. But suppose that thy father has not been guilty of exaction, whence hast thou thy money? If indeed thou answerest, “From myself;” thou art ignorant of God, not having the knowledge of thy Creator; but if, “From God,” tell me the reason for which thou receivedst it. Is not the earth and the fulness thereof the Lord’s? (Ps. 24:1.) If then whatever is ours belongs to our common Lord, so will it also belong to our fellow-servant.
