“But that many of us are called poor, this is not our disgrace, but our glory; for as our mind is relaxed by luxury, so it is strengthened by frugality, and yet who can be poor if he does not want, if he does not crave for the possessions of others, if he is rich towards God? He rather is poor, who, although he has much, desires more.”
Tertullian (160-220) in Apologetical Works, Argument XXXVI.
