The world does not consist of 100 percent Christians and 100 percent non-Christians. There are people (a great many of them) who are slowly ceasing to be Christians but who still call themselves by that name: some of them are clergymen. There are other people who are slowly becoming Christians though they do not yet call themselves so.
C. S. LewisThe value given to the testimony of any feeling must depend on our whole philosophy, not our whole philosophy on a feeling.
C. S. LewisNo one returns from Christianity to the same state he was before Christianity but into a worse state: the difference between a pagan and an apostate is the difference between an unmarried woman and an adulteress. For faith perfects nature but faith lost corrupts nature. Therefore many men of our time have lost not only the supernatural light but also the natural light which pagans possessed.
C. S. Lewis
