I would like to understand the reasoning behind the belief that even legal rules of divine origin would include mention of things human culture would have had no concept of, and human language no word for, in the time the rule was made — such that the rules would be "complete for all future time" rather than "those relevant as of the time of covenant."
Wouldn't even a god think it more optimal to hold off on telling us rules about e.g. which synthetic meats are kosher, until we invent such things?
It seems awfully suspicious to the validity of that interpretation, that there are plenty of specific/concrete prohibitions given amongst divine rulings, but of those, none are about things that were entirely mysterious at the time, written down "as spoken" without understanding, only able to be made sense of centuries/millennia later.
In fact — the Hebrew god is an intercessor god, not an absent god; don't they already "amend" their own previous rules whenever they communicate specific orders / demands / requirements to particular people? Does that not, by itself, disrupt the interpretation of the initial set of laws given being a perfect closed set, never to be updated, applicable to all future circumstances? Would a perfect body of divine law not already imply those orders / demands / requirements, such that there would be no need for further communication?
