Francesco Saverio Nitti quotes

The doctrines held by the early Fathers of the Church on the nature of property are perfectly uniform. They almost all admit that wealth is the fruit of usurpation, and, considering the rich man as holding the patrimony of the poor, maintain that riches should only serve to relieve the indigent; to refuse to assist the poor is, consequently, worse than to rob the rich. According to the fathers, all was in common in the beginning: the distinctions mine and thine, in other words, individual property, came with the spirit of evil.
