“What is the purpose of liturgy? It turns out that novelty (free-form 'lack of liturgy') 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 waste to one's devotion.

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
