Josef Pieper, Leisure: The Basis of Culture:
"[T]he world of 'work' and of the 'worker' is a poor, impoverished world, be it ever so rich in material goods; for on an exclusively utilitarian basis, that is, of the world of 'work,' genuine wealth, wealth which implies overflowing into superfluities, into unnecessaries, is just not possible. Wherever the superfluous makes its appearance it is immediately subjected to the rationalist, utilitarian principle of the world of work. And, as the traditional Russian saying puts it: work does not make one rich, but round-shouldered.
On the other hand, divine worship, of its very nature, creates a sphere of real wealth and superfluity, even in the midst of the direst material want -- because sacrifice is the living heart of worship. And what does sacrifice mean? It means a voluntary offering freely given. It definitely does not involve utility; it is in fact absolutely antithetic to utility. Thus, the act of worship creates a store of real wealth that cannot be consumed by the workaday world. It sets up an area where calculation is thrown to the winds and goods are deliberately squandered, where usefulness is forgotten and generosity reigns. Such wastefulness is, we repeat, true wealth; the wealth of the festival time. And only in this festival time can leisure unfold and come to fruition."
