I don't know. Pollock crashed his car into a tree while driving drunk. Bad role model. How about Salvador Dali? He had some nice religious paintings. But then, he was a voyeur who dabbled in the occasional orgy, so probably not. 

Boy, this character business gets really complicated. I'm now vetting a guy who paints dogs playing poker, and so far he seems clean. I just don't know where I'd hang his stuff in church...
