'Seeing' religious art

Some interesting discussion on The Guardian's Cif Belief pages at the moment responding to the question 'Do we need faith to see religious art?'  Here's a brief quote from Catherine Pepinster's response:

Is [religious art] really appreciated by those who don't believe? Can they fully understand it, indeed conceive of these other minds in another time and place where faith held sway?

That must depend on the extent to which the viewer can accept the possibility of the divine, or the existence of the religious impulse. I suspect that there is a growing tendency, for all Richard Dawkins's efforts, for people to accept that there is such an impulse.
