If there were such a society in existence and you or I visited it, I think we should come away with a curious impression. We should feel that its economic life was very socialistic and, in that sense, 'advanced,' but that its family life and its code of manners were rather old fashioned--perhaps even ceremonious and aristocratic. Each of us would like some bits of it, but I am afraid very few of us would like the whole thing. That is just what one would expect if Christianity is the total plan for the human machine. We have all departed from that total plan in different ways, and each of us wants to make out that his own modification of the original plan is the plan itself. You will find this again and again about anything that is really Christian: every one is attracted by bits of it and wants to pick out those bits and leave the rest. That is why we do not get much further: and that is why people who are fighting for quite opposite things can both say they are fighting for Christianity.
C. S. Lewis, Mere Christianity, chapter 13
