Quite simply, there is no formation without repetition. There is no habituation without being immersed in a practice over and over again… So it is precisely our allergy to repetition in worship that has undercut the counterformative power of Christian worship—because all kinds of secular liturgies shamelessly affirm the good of repetition. We’ve let the devil, so to speak, have all the repetition. And we, as liturgical animals, are only too happy to find our rhythms in such repetition. Unless Christian worship eschews the cult of novelty and embraces the good of faithful repetition, we will constantly be ceding habituation to secular liturgies.
We need stories like we need food and water: we're built for narrative, nourished by stories, not just as distractions or diversions or entertainments but because we constitute our world narratively. It is from stories that we receive our "character," and those stories in turn become part of our background, the horizons within which we constitute our world and engage in action. I cannot answer the question, what do I love? without (at least implicitly) answering the question what story do I believe? We tell ourselves stories in order to live.
