Eve writes (inter alia):

You could say that a work of art which requires the viewer to be Catholic already is a smaller work of art than one which commands a more universal audience.

But I wouldn't. I would say that a work of art that shows the viewer that he's already Catholic without knowing it -- because otherwise, he couldn't appreciate the work of art, yet he plainly does -- is plainly great.

Eve writes about a pre-conversion trip to Rome, and finding it very alien. I too visited Rome pre-conversion, and found it to be home. This was the more remarkable, because the same trip took in England, which also (in a very different way) felt very home-y -- only I was expecting it too. Rome's homelikeness took me by surprise.
