Thank you! I've taken a little break from game-dev, but will work on stuff again soon. I'll get back to you in a few days with where the holy symbol is (out of town and don't have access to the game at the moment).
In the upper left-hand part of the town map (NW) there is a building called "The Guild." Once enough of the passages are cleared, talk to the Guildmaster, he will give you the Holy Symbol.
Sorry it took a little longer to get to the files for this than I had thought it would.
