Repetition can be a good thing, or at least carry good effect, and my own regular celebration of the Eucharist, and participation in it, has had many good, habit-forming effects (I believe). But I see his point, and it is one I share and like occasionally to highlight, by commenting, when asked, that I celebrated the Eucharist and 'no-one was hurt'.
I don't want anyone to be hurt. Of course not. But I want us to be changed by it; even shocked and shaken (or if not shaken, stirred). And that's, surely, the danger of too much repetition of this central liturgical happening of Christian life: the weight-carrying, meaning-carrying message and narrative which the Eucharist embodies and asserts ought not become 'just a thing'.
I have sometimes heard other clergy speak in emotive and disturbingly cosy terms of celebrating the Eucharist "and encountering Jesus there" and of finding such daily liturgical adventures to be essential to life. I am uneasy with this kind of perspective. Encounters with the Risen Christ are not confined to liturgy (there's surely a case for saying the Risen Christ might be far more interested in speaking to us in the ordinary business of living). And liturgy should shake us up from time to time. Hard hats on!
