Yes, it does depend entirely on how we understand worship. But, say I, the question is better put as how we ought to understand worship; and that IMHO means simultaneously two things--(1) an appreciation of our ENTIRE historical tradition of worship, as well as (2) how we moderns are inclined towards the spiritual. I am appalled that the historical dimension is missing from the project described in this story.

We know that our post V2 liturgical changes, including much that happened in archetecture, was driven by deep knowledge of the entire history of  Christian worship, but, say I, there was and remains an abysmal failure by the magisterium to convey that history in sufficient detail for ALL of the people of God to grasp the wisdom of the reform. Without the full history, we end up, as we have, with our cultural liturgical wars. Sad!
