"The advantage of a fixed form of service is that we know what is coming. Ex Tempore public prayer has this difficulty: we don't know whether we can mentally join in it until we've heard it - and it might be phoney or heretical. We are therefore called upon to carry on a critical and a devotional activity at the same moment: two things hardly compatible. In a fixed form we ought to have 'gone through the motions' before in our private prayers; the rigid form really sets our devotions free. I also find the more rigid it is, the easier it is to keep one's thoughts from straying. Also it prevents getting too completely eaten up by whatever happens to be the preoccupation of the moment (i.e. the election, or what not). The permanent shape of Christianity shows this." (from The Business of Heaven)

I like it.

I love C.S. Lewis ^_^

pity he didn't become Catholic

What books is it from? (Business of Heaven is, as far as I know, a "best of" book, containing small pieces from other works.)
