Maybe you don't hear about God a lot in the Disney versions of fairy tales, but holy cannoli are the Grimms' Fairy Tales full of religious references. We get saints, baby Jesus, the devil, and other church-y stuff. Sure, some of the tales are pure fluffy fun (wolves are fluffy, right?), but a fair few of them deal with how to get into heaven and avoid hell. Which was serious business back in the day, and still is for many.
The tales express a purely Christian perspective on the world.
The tales give a set of consistent directions for how to act in accordance with religious norms, and not just when we're encountering a Big Bad Wolf.
