Frugality is a sin in this respect: that it arises from the love of possessing. In contrast, we should both abstain from pleasures and by no means withhold money. To use money sparingly, that is, moderately, is a type of weakness of the mind. It reveals someone fearing lest he will be in need. Or it reveals someone despairing of being able to recover it, or someone incapable of the contempt of earthly things.
--Lactantius
