The motive for criticizing myth, that is, its objectifying representations, is present in myth itself, insofar as its real intention to talk about a transcendent power to which both we and the world are subject is hampered and obscured by the objectifying character of its assertions.
Contemporary Christian proclamation is faced with the question whether, when it demands faith from men and women, it expects them to acknowledge this mythical world picture from the past. If this is impossible, it has to face the question whether the New Testament proclamation has a truth that is independent of the mythical world picture, in which case it would be the task of theology to demythologize the Christian proclamation.
It is impossible to repristinate a past world picture by sheer resolve, especially a mythical world picture, now that all of our thinking is irrevocably formed by science. A blind acceptance of New Testament mythology would be simply arbitrariness; to make such acceptance a demand of faith would be to reduce faith to a work.
It may be said that myths give to the transcendent reality an immanent, this-worldly objectivity. Myths speak about gods and demons as powers on which man knows himself to be dependent, powers whose favors he needs, powers whose wrath he fears. Myths express the knowledge that man is not master of the world and his life, that the world within which he lives is full of riddles and mysteries and that human life also is full of riddles and mysteries.
