Most of the conversation on ministerial formation is a load of crock. I suspect we engage in a little false advertising along the lines of: "Be transformed in three easy steps or your money back."
I am an almost classic case of the evangelical on the Canterbury Trail, but I don’t see the evidence that the graceful aestheticism of liturgy “produces” gracious persons or that worshiping in the beauty of holiness makes holy persons.
There are questions, of course, about what constitutes a matter of taste. But few of us would really disagree that once you do find that mystical territory of taste, rational argument doesn’t enter into it.
