From Dietrich Bonhoeffer:
Man at his origin knows only one thing: God. It is only in the unity of his knowledge of God that he knows of other men, of things, and of himself. He knows all things only in God, and God in all things. The knowledge of good and evil shows that he is no longer at one with this origin….The knowledge of good and evil is … separation from God. Only against God can man know good and evil….In the knowledge of good and evil man does not understand himself in the reality of the destiny appointed in his origin, but rather in his own possibilities, his possibility of being good or evil. He knows himself … as something apart from God, outside God.
