An interesting thought occurred to me after talking about how a particular sort of bad writing in a detective story is analogous to the Gnostic and Aryan heresies: in any fiction in which there is a Christ figure, all of the historical Christian heresies will be available as bad ways to write the story.
Or, to put it another way, in fiction which has a Christ figure, the things you shouldn’t do in that story will be analogous to one or more of the historical Christian heresies.
