I do understand your concern tho: a submission to something external must be exactly that, and many in their religious practice(s) simply rewrite, rename, and grant excess authority to their own (albeit “higher” in some sense) whims.
So I do think this is a valid and sound concern…
Nevertheless, to make it a rule or principle presumes total knowledge of the data. If even one religious experience is legitimately-divine, this is not the case, and to ignore such a possibility is to presume your own conclusion, i.e. the fallacy of begging the question.
