The Devil is not the Prince of Matter; the Devil is the arrogance of the spirit, faith without smile, truth that is never seized by doubt. The Devil is grim because he knows where he is going, and, in moving, he always returns whence he came.
Umberto EcoTo escape the power of the unknown, to prove to yourself that you don't believe in it, you accept its spells. Like an avowed atheist who sees the Devil at night, you reason: He certainly doesn't exist; this is therefore an illusion, perhaps a result of indigestion. But the Devil is sure that he exists, and believes in his upside-down theology. What, then, will frighten him? You make the sign of the cross, and he vanishes in a puff of brimstone.
Umberto EcoBut why do some people support [the heretics]?" "Because it serves their purposes, which concern the faith rarely, and more often the conquest of power." "Is that why the church of Rome accuses all its adversaries of heresy?" "That is why, and that is also why it recognizes as orthodoxy any heresy it can bring back under its own control or must accept because the heresy has become too strong.
