“Devil and God are two sides of the same face.”

Light (1919), Ch. XVI - De Profundis Clamavi

Die deutsche Einheit und die europäische Einigung sind zwei Seiten ein und derselben Medaille.

1900s, A Square Deal (1903)
Context: The average American knows not only that he himself intends to do what is right, but that his average fellow countryman has the same intention and the same power to make his intention effective. He knows, whether he be business man, professional man, farmer, mechanic, employer, or wage-worker, that the welfare of each of these men is bound up with the welfare of all the others; that each is neighbor to the other, is actuated by the same hopes and fears, has fundamentally the same ideals, and that all alike have much the same virtues and the same faults. Our average fellow citizen is a sane and healthy man who believes in decency and has a wholesome mind. He therefore feels an equal scorn alike for the man of wealth guilty of the mean and base spirit of [arrogance]] toward those who are less well off, and for the man of small means who in his turn either feels, or seeks to excite in others the feeling of mean and base envy for those who are better off. The two feelings, envy and arrogance, are but opposite sides of the same shield, but different developments of the same spirit.

Some Reasons Why (1881)
Context: The believer in the inspiration of the Bible is compelled to say, that there was a time when slavery was right, when women could sell their babes, when polygamy was the highest form of virtue, when wars of extermination were waged with the sword of mercy, when religious toleration was a crime, and when death was the just penalty for having expressed an honest thought. He is compelled to insist that Jehovah is as bad now as he was then; that he is as good now as he was then. Once, all the crimes that I have mentioned were commanded by God; now they are prohibited. Once, God was in favor of them all; now the Devil is their defender. In other words, the Devil entertains the same opinion to-day that God held four thousand years ago. The Devil is as good now as Jehovah was then, and God was as bad then as the Devil is now.
