It would be really interesting if a religion kept a chronicle of its own development from its own current perspective, never modifying past entries, but constantly reflecting upon and reinterpreting the older perspective in terms of the latest one.

(Imagine a collective version of a child writing a continuous diary, starting from infancy, each session reading the story so far, then continuing it.)

The chronicle might start of as a purely mythical self-interpretation of a mythical existence. Then it might progress to a more institutionalized state and formally self-interpret its formalization, and so on all the way to its development into an pluralistic interpersonal religion, and offer pluralistic self-interpretations of its own pluralistic existence and its harmoniously divergent views on its past and future.

The only drawback to the experiment would be if some reckless Prometheus-type were to hand the work to wild readers from a more primitive stage of development. Would they even grasp it as a chronicle? They might see it as a catalogue of true factual assertions. They might misinterpret truths they’re unprepared to grasp, like children attempting but failing to make sense of the adult world.
