The devil’s sage advice to his apprentice in C.S. Lewis’ The Screwtape Letters:
What we want, if men become Christians at all, is to keep them in the state of what I call ‘Christianity And.’ You know–Christianity and the Crisis, Christianity and the New Psychology, Christianity and the New Order, Christianity and Faith Healing, Christianity and Psychical Research, Christianity and Vegetarianism, Christianity and Spelling Reform…Substitute for the faith itself some Fashion with a Christian colouring. Work on their horror of the Same Old Thing. The horror of the Same Old Thing is one of the most valuable passions we have produced in the human heart–an endless source of heresies in religion, folly in counsel, infidelity in marriage, an inconstancy in friendship. (quoted by Michael Horton in Always Reformed: Essays in Honor of Robert Godfrey)
Romans 8:28
