@GabeWillard: Your edit improved the question, still I'm not sure what exactly your problem is. If you use religion like Eddings does in a fantasy world, then why should anyone think of it as propaganda? Or do you want to convince people? That is problematic in a fiction novel no matter if it's about religion or something else.
In your novel you are describing the faith of your characters, so normally you do not have to express any viewpoint you have about your religion in the real world.
