Rationalism shifts the center from God and his law-word, his summons to believe and obey, to man as rationalist, sitting in judgment upon God and man. The arrogance of rationalism is its assumption that man the philosopher can sit in judgment over God and man, and all things else. We cannot be Christians on our terms, only on God's terms. Our conversion is not the result of a bargain with God but rather our total submission on his terms only. Man is a creature, God's creature, and he must use his reason to think God's thoughts after him, not to attempt to establish what God has already ordained, not to seek to provide independent premises for knowledge.
Rationalism creates an artificial man, one in whose being neither sin nor conscience have any part.
Such a man does not exist.
