America Founded on Rule of Law
The United States was founded during a period known as The Enlightenment, or the philosophical Age of Reason. From Wikipedia: "The era is marked politically by governmental consolidation, nation creation, greater rights for the common people, and a diminuation of the influence of authoritarian institutions".
The founding fathers were strongly influenced by this era of freethought, and by the preceding events of the Protestant Reformation in England and Europe. The Reformation was a period when the corruption and excesses of the Catholic church were brutally overthrown. Although on the surface the overthrow was based on religious differences, in reality it was more a struggle between the two ruling powers of the day - the Crown and the Church. More than theology, it was about power, money, and property.
Those who resisted British rule were very familiar with a system of government that was strongly influenced and controlled by the church. In God vs. the Gavel: Religion and the Rule of Law, Marci A. Hamilton explains how Western law changed to bring churches and other religious institutions under the umbrella of neutral, generally applicable laws:"Before the common law and its equalizing principles were entrenched and before the creation of the United States, churches did have autonomy from the law. The rights of religious institutions and their clergy were above those of ordinary citizens. From the 3rd to the 16th centuries in Britain, church autonomy was in fact the order of the day."
Regarding the Christian church vs. the rule of common law, Thomas Jefferson wrote in a letter to Major John Cartwright, June 5, 1824: "I was glad to find in your book a formal contradition, at length, of the judiciary usurpation of legislative powers; for such the judges have usurped in their repeated decisions, that Christianity is a part of the common law. The proof of the contrary, which you have adduced, is incontrovertible; to wit, that the common law existed while the Anglo-Saxons were yet Pagans, at a time when they had never yet heard the name of Christ pronounced, or knew that such a character had ever existed."
Jefferson's Notes on the State of Virginia: "By our own act of assembly of 1705, c. 30, if a person brought up in the Christian religion denies the being of a God, or the Trinity, or asserts ther are more gods than one, or denies the Christian religion to be true, or the scriptures to be of divine authority, he is punishable on the first offence by incapacity to hold any office or employment ecclesiastical, civil, or military; on the second by disability to sue, to take any gift or legacy, to be guardian, executor, or administrator, and by three years' imprisonment without bail."
"This is a summary view of that religious slavery under which a people have been willing to remain, who have lavished their lives and fortunes for the establishment of their civil freedom. The error seems not sufficiently eradicated, that the operations of the mind, as well as the acts of the body, are subject to the coercion of the laws."
"Had not the Roman government permitted free inquiry, Christianity could never have been introduced. Had not free inquiry been indulged at the era of the reformation, the corruptions of Christianity could not have been purged away. If it be restrained now, the present corruptions will be protected, and new ones encouraged."
"Here I might defy the best read lawyer to produce another scrip of authority for this judiciary forgery; and I might go on further to shew, how some of the Anglo-Saxon priests interpolated into the text of Alfred's laws, the 20th, 21st, 22nd and 23rd chapters of Exodus, and the 15th of the Acts of the Apostles, from the 23rd to the 29th verses. But this would lead my pen and your patience too far. What a conspiracy this, between Church and State!"
Jefferson is obviously very familiar with a system of government that had been corrupted by religion. He and the other founding fathers were committed to establishing a nation that would be governed by the Rule of Law, and that would derive its power from the rights of the common people, not the theocracy of the church.
