I'm currently reading too many books. Maybe I'm just avoiding practicing. In any case I came across this idea in Subversive Orthodoxy by Robert Inchausti.
"For [William] Blake, a person who is not an artist cannot be a Christian, for the creative imagination is the only vehicle through which love of one's fellow man can be grasped."
I'm not sure what to think of it. I think imagination is very important for a Christian. We must be able to imagine alternatives to that which we see around us, but is imagination a vehicle for grasping love? I'm not even sure what that means. Unfortunately I can't find the original quote, so it's hard to tell.
