[M]an’s nature, so to speak, is a perpetual factory of idols. After the Flood there was a sort of rebirth of the world, but not many years passed by before men were fashioning gods according to their pleasure … Man’s mind, full as it is of pride and boldness, dares to imagine a god according to its own capacity; as it sluggishly plods, indeed is overwhelmed with the crassest ignorance, it conceives an unreality and an empty appearance as God.
To these evils a new wickedness joins itself, that man tries to express in his work the sort of God he has inwardly conceived. Therefore the mind begets an idol; the hand gives it birth. The example of the Israelites shows the origin of idolatry to be that men do not believe God is with them unless he shows himself physically present.
