Okay, correct this perceived dialogue to reflect how you would truly answer:
Me: Which god is where the buck stops?
You (as I think you would say): The only god with which we have to do. Elohim. Heavenly Father.
Me: So, this god, whom you call Elohim, has all universal authority? No other god in the universe or any other universe or any other spiritual dimension has authority he doesn't have, or this god did not derive any authority from him?
You (as I think you might say): I didn't say that. I don't have to be concerned with that authority. I only have to be concerned with his authority.
Me: But what if other gods or any other higher-up god pulls rank on your god? Does that not militate against your claim that your god has "ultimate" authority if another god can pull rank on him? "Ultimate" authority that is not ultimate is not ultimate. [Wow! Did I really have to say that, or have you just not been getting what I've been trying to say?]
The child of God can NOT go beyond what the Heavenly Father or Son has spoken or has made known unto his servants!
