Christian Mythology, the stories that Xeph is talking about, were slowly created and refined orally by Judaism cultures, like any other mythlology set. The religion fairy tales, it very much depends on the story itself. Many were created by the church and then propogated to help Christianity dominated, but some are old "paganistic" fairy stories twisted into something that won't get the storyteller arrested for being a heretic. And still some, the "younger ones" are truly created by the masses.
A similar evolution can be found in the fairy stories that everyone knows. In the original oral stories, the girls portrayed as getting into trouble (the red riding hood archetype) either save themselves through their own clever minds, or they die. However, the brothers Grimm and Perrault, when they moved the stories from oral to written, changed things, because they did not believe little girls of the noble class should hear such horrid things. Grimm just edited them slightly, but Perrault practically outright killed them. Hence, fairy stories that we all know and love show the female heroines fainting and calling for help alot. And being rescued by big strong men whom they must immediately marry.
