The belief in revelation exhibits in the clearest manner the characteristic illusion of the religious consciousness. The general premiss of this belief is: man can of himself know nothing of God; all his knowledge is merely vain, earthly, human. But God is a superhuman being; God is known only by himself. Thus we know nothing of God beyond what he reveals to us. The knowledge imparted by God is alone divine, superhuman, supernatural knowledge. By means of revelation, therefore, we know God through himself; for revelation is the word of God--God declaring himself. Hence, in the belief in revelation man makes himself a negation, he goes out of and above himself; he places revelation in opposition to human knowledge and opinion; in it is contained a hidden knowledge, the fulness of all supersensuous mysteries; here reason must hold its peace. But nevertheless the divine revelation is determined by the human nature. God speaks not to brutes or angels, but to men; hence he uses human speech and human conceptions. Man is an object to God, before God perceptibly imparts himself to man; he thinks of man; he determines his action in accordance with the nature of man and his needs. God is indeed free in will; he can reveal himself or not; but he is not free as to the understanding; he cannot reveal to man whatever he will, but only what is adapted to man, what is commensurate with his nature such as it actually is; he reveals what he must reveal, if his revelation is to be a revelation for man, and not for some other kind of being. Now what God thinks in relation to man is determined by the idea of man--it has arisen out of reflection on human nature. God puts himself in the place of man, and thinks of himself as this other being can and should think of him; he thinks of himself, not with his own thinking power, but with man's. In the scheme of his revelation God must have reference not to himself, but to man's power of comprehension. That which comes from God to man, comes to man only from man in God, that is, only from the ideal nature of man to the phenomenal man, from the species to the individual. Thus, between the divine revelation and the so-called human reason or nature, there is no other than an illusory distinction;--the contents of the divine revelation are of human origin, for they have proceeded not from God as God, but from God as determined by human reason, human wants, that is, directly from human reason and human wants. And so in revelation man goes out of himself, in order, by a circuitous path, to return to himself! Here we have a striking confirmation of the position that the secret of theology is nothing else than anthropology--the knowledge of God nothing else than a knowledge of man!
