This post features commentary by Dr. Gregg Frazer on the Bible as an intellectual source of republicanism. I'd count the Bible/Christian principles as one source of many from which America's Founders believed man's reason could select the "rational" parts. But it was by no means the chief source. Pagan Greco-Roman principles, the interest in which had been recently rekindled during the Renaissance, received far more attention in the Federalist Papers. Given Christianity is compatible with a variety of different political systems, Christianity is arguably perfectly compatible with republicanism. But the principles of republicanism are for the most part a-biblical.
The fact that some parts of the Declaration and/or Constitution are not in conflict with verses in the Bible does not mean that the Bible was the source. This is especially important when — as in the case of the Declaration and the Constitution — the authors claim other sources, but do not claim the Bible as a source!
In a May 8, 1825 letter to Henry Lee, Jefferson identifies his sources for the Declaration’s principles. He names as sources: Aristotle, Cicero, Locke, and (Algernon) Sidney — he does not mention the Bible. Then again, the terminology in the Declaration is not specifically Christian — or even biblical, with the exception of “Creator.” The term “providence” is never used of God in the Bible, nor are “nature’s God” or “Supreme Judge of the world” ever used in the Bible.
In the hundreds of pages comprising Madison’s notes on the constitutional convention (and those of the others who kept notes), there is no mention of biblical passages/verses in the debates/discussions on the various parts and principles of the Constitution. They mention Rome, Sparta, German confederacies, Montesquieu, and a number of other sources — but no Scripture verses.
In The Federalist Papers, there is no mention of biblical sources for any of the Constitution’s principles, either — one would think they could squeeze them in among the 85 essays if they were, indeed, the sources; especially since the audience was common men who were familiar with, and had respect for, the Bible. The word “God” is used twice — and one of those is a reference to the pagan gods of ancient Greece. “Almighty” is used twice and “providence” three times — but neither is ever used in connection with any constitutional principle or influence. The Bible is not mentioned.
As for freedom and liberty in the Bible, it is always SPIRITUAL freedom/liberty — as a look at the verses you’ve listed IN CONTEXT shows. That is NOT to say that political liberty is an anti-biblical concept — it’s just not a biblical one. Arguing that it is a “Calvinist” concept does not make it a biblical one, either. The “disciples” of Calvin did not write inspired revelation.
The key Founders (J. Adams, Washington, Jefferson, Franklin, Madison, Hamilton, Wilson, & G. Morris) — those most responsible for the founding documents — were religious, but not Christians. They believed that religion was essential to produce the morality that a free society required, but that any religion would suffice. Their religious belief was a mixture of Protestantism, natural religion, and rationalism — with rationalism as the trump card and decisive factor. They retained elements of Christianity, but rejected the elements of Christianity (and of natural religion) that they considered irrational. However: of the ten CORE beliefs of Christianity (those shared by all of the major Protestant denominations of the day (and by the Catholics), they held to only one (or two, in some cases). Their belief system was, as I have termed it, theistic rationalism.
If the view of Adams, Jefferson, and Franklin that any/all religions were valid paths to God and that any/all religions would suffice to produce the morality needed was a “minority opinion” among the Founders, why were they chosen to write the philosophical (you say religious) document (Declaration)?
