Like the game so far, absolutely loath the church. They seem to only exist to steal money or power from the player, and you lose if you destroy them. Yes, the goddess the worship is kind of your patron (I'm assuming), but other than that there isn't really a reason why you'd want to help them.
Missionaries? Don't need them, money's tight as it is. Selling magical goods? Another good source of income! Going after the succubus brothel? You do know what kind of game this is, right? Closing schools, 'free' church renovation, more power to the church? All terrible! Mechanically you do need to lend the church a hand, otherwise you lose, but story wise they aren't presenting a good case as to why I should be making these concessions just to make them happy.
