I was wondering if anyone knew what Purity, Corruption, violent and peaceful have to with how effective a priest or what bearing it has when a priest gets one of these traits? I allready figured out what orthodox and unorthodox traits do (the hard way) and was wondering if anyone knew what these traits do for a priest?

I also heard that sending a priest to a province with low faith in whatever your factions religion is helps to increase a priests piety but so far my +2 piety priest has only gotten unorthodox traits from being in a region with low faith so far.
