“Therefore we are not dealing here with the philosophical knowledge of man, which defines man as a rational animal and so forth. Such things are for science to discuss, not for theology. So a lawyer speaks of man as an owner and master of property, and a physician speaks of man as healthy or sick. But a theologian discusses man as a sinner. In theology, this is the essence of man. The theologian is concerned that man become aware of this nature of his, corrupted by sins.”
-Martin Luther on Psalm 51
