When a people refuse to be self-governed by God and biblical morality, they will be ruled by the tyranny of men... and clamor for it, justify it and insist upon it's need.
Here we are.
In history, the opposite is the most common scenario. Religion and its related moral authority...have imposed tyranny and destroyed self governance. As for "biblical" authority, I presume you mean your personal understanding of its meaning and purpose...one of a nearly countless set of perceptions and understandings of such authority. Further, you presume your own view of god is clearer than that of others...a belief that can only be held through a combination of ignorance and arrogance. Islamists, for example, assert Koranic authority in much the same way. Christians in late Roman and Medieval times made similar use of Biblical authority to slaughter innocents and annihilate free thought.
Why should your version be any better than past religious tyrannies...or is it because only you know what god wants based on your personal understanding of the bible? No arrogance or ignorance there, right?
This is why men like Thomas Jefferson, though acknowledging important moral lessons that can be taken from religion...and from the bible specifically...fought so hard to ensure religion was not only free from government influence, but also that government not be free of the overt religious "orthodoxy" of sects or individuals believing they, and they alone, know the truth of god.
Mr. Jefferson says it much more eloquently than I ever could, and with even more conviction:
In every country and in every age, the priest has been hostile to liberty. He is always in alliance with the despot, abetting his abuses in return for protection to his own.-Thomas Jefferson, letter to Horatio G. Spafford, March 17, 1814
History, I believe, furnishes no example of a priest-ridden people maintaining a free civil government. This marks the lowest grade of ignorance of which their civil as well as religious leaders will always avail themselves for their own purposes.-Thomas Jefferson to Alexander von Humboldt, Dec. 6, 1813.
Christianity neither is, nor ever was a part of the common law.-Thomas Jefferson, letter to Dr. Thomas Cooper, February 10, 1814
Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between church and State.-Thomas Jefferson, letter to Danbury Baptist Association, CT., Jan. 1, 1802
But it does me no injury for my neighbor to say there are twenty gods or no God. It neither picks my pocket nor breaks my leg.-Thomas Jefferson, Notes on Virginia, 1782
Where the preamble declares, that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed by inserting "Jesus Christ," so that it would read "A departure from the plan of Jesus Christ, the holy author of our religion;" the insertion was rejected by the great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.-Thomas Jefferson, Autobiography, in reference to the Virginia Act for Religious Freedom
And the other FF's often found common ground on this topic with Thomas Jefferson.
"Experience witnesseth that ecclesiastical establishments, instead of maintaining the purity and efficacy of religion, have had a contrary operation. During almost fifteen centuries has the legal establishment of Christianity been on trial. What has been its fruits? More or less, in all places, pride and indolence in the clergy; ignorance and servility in the laity; in both, superstition, bigotry and persecution." --- James Madison, "A Memorial and Remonstrance", 1785
The blackest billingsgate, the most ungentlemanly insolence, the most yahooish brutality, is patiently endured, countenanced, propagated, and applauded. But touch a solemn truth in collision with a dogma of a sect, though capable of the clearest proof, and you will find you have disturbed a nest, and the hornets will swarm about your eyes and hand, and fly into your face and eyes." --- John Adams, letter to John Taylor on the priesthood
