The most interesting thing about the Saint Cuthbert article was the insistance that Cuthbert really is a good deity, Player's Handbook notwithstanding.
Harsh, unbending, and (largely) humorless, yes. Prone to violence, yes. But also humble, charitable, and even kind in a very rough way. The church really emphasizes an 'all are created equal' type of lawfulness over the more hierarchical lawfulness you see in a lot of lawful D&D churches. Humility and common sense are played up big time.
It made me think that a cleric of St. Cuthbert would be great for playing a down home 'country doctor' type who doesn't hold with new-fangled silliness and slick talk. You could do a Granny Weatherwax type easily.
