The doctrine of the Devil is too easy an excuse for human failure; it tempts us to leave this world to the control of the "god of this world," and to wait for salvation through some super-earthly power. Or else it sunders the unity of mankind, the children of God. Those who recognize a Devil often hold that some group or nation or sect are the Devil's own- the witches, the heretics, the Jews, the capitalists, the communists- and these enemies of God are no longer entitled to the rights, the just dealing, the simple humanity which are the heritage of all created in the divine image.
