‘I hope no reader will suppose that “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… 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… You must regard it as waiting, not as camping. You must keep on praying for light: and, of course, even in the hall, you must begin trying to obey the rules which are common to the whole house. And above all you must be asking which door is the true one; not which pleases you best by its paint and paneling.
‘In plain language, the question should never be: “Do I like that kind of service?” but “Are these doctrines true: Is holiness here? Does my conscience move me towards this? Is my reluctance to knock at this door due to my pride, or my mere taste, or my personal dislike of this particular door-keeper?”’ – C.S. Lewis, Mere Christianity
