35 God, Who provides for all with counsels of supreme bounty, has ordained that for the exercise of virtues and for the testing of one's worth there be in the world rich and poor; but He does not wish that some have exaggerated riches while others are in such straits that they lack the bare necessities of life. But a kindly mother of virtue is honest poverty which gains its living by daily labor in accordance with the scriptural saying: "Give me neither beggary, nor riches: give me only the necessaries of life" ( Proverbs XXX: 8).
