The ad orientem kerfuffle, in the wake of Cardinal Sarah’s address, has if nothing else, shown how passionately people on all sides of the matter care about Liturgy.

The cultivation of culture—first, among Catholics themselves, and then outwards from there—depends on a proper cultus, a liturgy in which God is sought and found.
