"They do not … apprehend God as he offers himself, but imagine him as they have fashioned him in their own presumption. When this gulf opens, in whatever direction they move their feet, they cannot but plunge headlong into ruin. Indeed, whatever they afterward attempt by way of worship or service of God, they cannot bring as a tribute to him, for they are worshipping not God but a figment and a dream of their own heart.

"Each man's mind is like a labyrinth, so that it is no wonder that individual nations were drawn aside into various falsehoods; and not only this - but individual men, almost, had their own gods. For rashness and superficiality are joined to ignorance and darkness, scarcely a single person has even been found who did not fashion for himself an idol or spectre in place of God. Surely just as waters boil up from a vast, full spring, so does an immense crowd of gods flow forth from the human mind, while each one, in wandering about with too much license, wrongly invents this or that about God himself."

John Calvin, The Institutes of the Christian Religion, I.iv.1, 12
