The Communists do have a god, the Dialectic of History, which guarantees everything that they're going to do and guarantees them victory; that's why they're fanatic.
Reinhold NiebuhrThe separation of church and state is necessary partly because if religion is good then the state shouldn't interfere with the religious vision or with the religious prophet. There must be a realm of truth beyond political competence, that's why there must be a separation of churches, but if religion is bad and a bad religion is one that gives an ultimate sanctity to some particular cause. Then religion mustn't interfere with the state - so one of the basic Democratic principles as we know it in America is the separation of church and state.
Reinhold NiebuhrGoodness, armed with power, is corrupted; and pure love without power is destroyed.
