For he who cannot restrain his desires, even if he should be surrounded by every kind of possessions, how can he ever be rich? Those, indeed, who are satisfied with their own property, enjoying what they have, and not casting a covetous eye on the substance of others, even if they be, as to means, of all men the most limited, ought to be regarded as the most affluent. For he who does not desire other people’s possessions, but is willing to be satisfied with his own, is the wealthiest of all.
—St. John Chrysostom, On Wealth and Poverty
