The authority of God is ontological meaning in His being. God shares neither His glory nor authority with anyone. So I am at a loss to understand what you are stating.
Of course He can use any means to teach people about Himself.

Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
I believe that you are mixing definitions because this is essentially a repeat of the first question. But I will attempt to answer
what I think you are saying:
A brief definition of the word "authority"
the power to determine, adjudicate, or otherwise settle issues or disputes; jurisdiction; the right to control, command, or determine.

As you can see, the noun carries with itself the ability to make independent judgments by itself.
Does the Bible have that? NO
It is true that the Bible is the only rule for both our faith and our practice, but that is simply stating that the Bible is kinda like a tape measure where we measure things to see if they meet the standard of God. At its most basic form, the Bible is ink on paper that contains words we believe are from God. Does that ink and paper, bound nicely together possess some sort of authority (as defined above)? Again, the answer is no.
I have no idea what the mod thought was being rude, but that was not my intent, OK?
