Nonetheless, naming the logical fallacy rather than pointing out the logical error is clearly an appeal to authority.
Also, you are demonstrating a lack of understanding of logical reasoning. We know most of what we know because we have authoritative sources for that knowledge -- if Isaac Newton discovered much it was because he stood on the shoulders of giants (or was that someone else?). The notion that everything must be argued from first principles and that nothing can be accepted as authoritative is sophistry. Were that the case, we couldn't argue for anything.
Argument from authority is NOT fallacious. Why would it be? If I say that I think that Ty Cobb batted .367 because I saw it in the baseball Encycloedia, that's an entirely reasonable argument. I may be wrong -- but my argument is logical and reasonable. The formal logic would go:
P1) The baseball Encyclopedia keeps accurate records of players' statistics.
P2) The B. Enc. states that Ty Cobb hit .367 lifetime.
Conclusion: Ty Cobb hit .367 lifetime.
Where's the logical flaw? Perhaps one of the premises is wrong, but the logic is flawless. I'll grant that argument from FALSE authority is iffy (which is probably what you meant in saying the Bible argues from authority). After all, if God is the actual creator of all moral rules of right and wrong, and the bible is the revealed word of God, appealling to His revealed Word is hardly fallacious. To make any sort of logical argument we must accept some starting premises. On whose "authority" are these accepted?
