The Archbishop of Canterbury recently published an article (in The Economist, I think), in which he compared those who had faith in the free market to solve all economic ills - as well as those of other ideologies - to idolators.

His reasoning is that an idol like the golden calf is the creation of man, and the great error is to ascribe god-like qualities to anything man made. It is an error because anything that man makes is not perfect and will, therefore, eventually fail you.
