@neologist,
I'll ignore your superstitious belief systems (as much as I can within the context given) and reiterate your dubious rhetoric (and my merited text) for your elucidation (and then I have to wash the dog as she is kinda smelly):
You said "Are we to suppose any other authority to be superior?"
I said "Sounds rather deterministic for a religionist preaching the necessity of free will."
To edify: your presumably omnipotent/omniscient special friend would be incapable of fee will, add this to your red herring of positing a supernatural authority in the first place, add this to the lack of any requirement (outside of your unnecessarily involved and incomprehensible superstitions) for there to be free will, and you have an impossible row to hoe, except of course through the promotion of ignorance, prejudice, superstition, theocracies, suspension of critical thinking, anti-science, war, massive amounts of wasted resources, political corruption, sexual inequality, TV and radio evangelism, multi-million dollar politically driven religious lobbying, etc.
