To me, the bishop appears to be someone who's a realist. He is devout in his own ways, but he doesn't have his head so far up his ass that he can't understand that he needs the connections and money to keep everything running smoothly. Many priests think that to be a devout person he must get rid of all worldly needs, but the world still revolves around money. Without someone handling money or soliciting donations, the temple won't be able to do their jobs right.
