If you are Christian you do not have to believe that all the other religions are simply wrong all through. If you are an atheist you do have to believe that the main point in all the religions of the whole world is simply one huge mistake. If you are a Christian, you are free to think that all these religions, even the queerest ones, contain at least some hint of the truth.

- Mere Christianity
There were really only two answers possible: either in Hinduism or in Christianity. Everything else was either a preparation for, or else (in the French sense) a vulgarization of, these. Whatever you could find elsewhere you could find better in one of these. But Hinduism seemed to have two disqualifications. For one thing, it appeared to be not so much a moralized and philosophical maturity of Paganism as a mere oil-and-water coexistence of philosophy side by side with Paganism unpurged; the Brahmin meditating in the forest, and, in the village a few miles away, temple prostitution, sati, cruelty, monstrosity. And secondly, there was no such historical claim as in Christianity.

- Surprised by Joy
It must be admitted by anyone who accepts Christianity, that an increased interest in it, or even a growing measure of intellectual assent to it, is a very different thing from the conversion of England or even of a single soul. Conversion requires an alteration of the will, and an alteration which, in the last resort, does not occur without the intervention of the supernatural.
