C. S. Lewis on novelty in the liturgy
Novelty may fix our attention not even on the service but on the celebrant. You know what I mean. Try as one may to exclude it, the question "What on earth is he up to now?" will intrude. It lays one's devotion waste. There is really some excuse for the man who said, "I wish they'd remember that the charge to Peter was Feed my sheep; not Try experiments on my rats, or even, Teach my performing dogs new tricks.
― C.S. Lewis, Letters to Malcolm: Chiefly on Prayer
