Altina mentions there's some sort of "turf war" between the factions in the church, which I don't remember from CS3!
The main games I remember this from is the Crossbell series. Basically there is something of a dispute between the division of the church that handles artifact retrieval (Gralsritter and related peoples) and the division which priests/bishops/etc are a part of that handles other things. I don't think much detail about the nature of the dispute has been given, and the one thing I know of that's been affected by this dispute is that the archbishop of Crossbell Cathedral has banned the Gralsritter from entering Crossbell since before the start of the series. ---
