“I hope no reader will suppose the ‘mere’ Christianity is here put forward as an alternative to the creeds of the existing communions - as if a man could adopt it in preference to Congregationalism or Greek Orthodoxy or anything else. It is more like a hall out of which doors open into several rooms. If I can bring anyone into that hall I shall have done what I attempted. But it is in the rooms, not the hall, that there are fires and chairs and meals. The hall is a place to wait in, a place from which to try the various doors, not a place to live in…When you have reached your own room, be kind to those who have chosen different doors and to those who are still in the hall.”
- C.S. Lewis - Preface to Mere Christianity.
