Now, according to the natural order instituted by divine providence, material goods are provided for the satisfaction of human needs. Therefore the division and appropriation of property, which proceeds from human law, must not hinder the satisfaction of man's necessity from such goods. Equally, whatever a man has in superabundance is owed, of natural right, to the poor for their sustenance. So Ambrosius says, and it is also to be found in the Decretum Graziani "The bread which you withhold belongs to the hungry; the clothing you shut away, to the naked; and the money you bury in the earth is the redemption and freedom of the penniless."
This is my favorite bit from Singer's "Famine, Affluence, and Morality", but it's not Singer. It's St. Thomas Aquinas. I guess that means that Catholicism is socialism.
Somehow this gets lost in translation. No, I don't think the passage above is any sort of evidence that Aquinas is advocating socialism. He's advocating "socialism", which, as far as I can tell, is not socialism but basically stuff that Beck doesn't like. So, it's more like goodness.
