You seem to be saying much the same thing you said before. The "appraiser" of the Higher Authority is apparently armed with a pre-existing set of principles by which to judge the validity and worthiness of the Higher Authority. ("I will follow X, because X meets my criteria for a Higher Authority.") Doesn't this make the Higher Authority the rough equivalent of an elected official?
"Christians, including Isaac Newton, believe that by examining the prophetic reliability of the Biblical text, as well as the circumstantial evidence of the death and resurrection of Jesus Christ; we can trust in the Biblical God's veracity. Couple that with personal experiences of supernatural transformation, and you have a group of people coming up with a Constitutional Republic."
What on earth does formation of a constitutional republic have to do with "prophetic reliability" and "personal experiences of supernatural transformation"?
A Constitutional Republic requires it's free citizens to act responsibly without having an arsenal pointed at them. Many of the Founding Fathers correctly pointed to the fact that this system would not work unless it's citizens:
1. Believed the Creator is the source of rights. Rights derived from another man can change with his opinion, where as the eternal Word of God is unchanging. Originally disagreements were settled by an examination of scripture on the matter.
2. Freedom does not work where sin abounds. Sin abounds where Biblical principles are not practiced. Our original laws were filtered through the principles in the Word of God.
3. Bad laws show no regard for Biblical principles.
Look here for examples of these ideas in practice.
