The real trouble about the set your patient is living in is that it is merely Christian. They all have individual interests, of course, but the bond remains mere Christianity. What we want, if men become Christians at all, is to keep them in the state of mind 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. If they must be Christians let them at least be Christians with a difference. Substitute for the faith itself some Fashion with a Christian colouring. Work on their horror of the Same Old Thing . . .
