This article does a good job of summing up what I've bee saying. America is not, in theory a Christian nation. Nor should it ever be.
The Christian Nation Myth
The Christian Nation Myth
Whenever the Supreme Court makes a decision that in any way restricts the intrusion of religion into the affairs of government, a flood of editorials, articles, and letters protesting the ruling is sure to appear in the newspapers. Many protesters decry these decisions on the grounds that they conflict with the wishes and intents of the "founding fathers."
Such a view of American history is completely contrary to known facts. The primary leaders of the so-called founding fathers of our nation were not Bible-believing Christians; they were deists. Deism was a philosophical belief that was widely accepted by the colonial intelligentsia at the time of the American Revolution. Its major tenets included belief in human reason as a reliable means of solving social and political problems and belief in a supreme deity who created the universe to operate solely by natural laws. The supreme God of the Deists removed himself entirely from the universe after creating it. They believed that he assumed no control over it, exerted no influence on natural phenomena, and gave no supernatural revelation to man. A necessary consequence of these beliefs was a rejection of many doctrines central to the Christian religion. Deists did not believe in the virgin birth, divinity, or resurrection of Jesus, the efficacy of prayer, the miracles of the Bible, or even the divine inspiration of the Bible.
These beliefs were forcefully articulated by Thomas Paine in Age of Reason, a book that so outraged his contemporaries that he died rejected and despised by the nation that had once revered him as "the father of the American Revolution." To this day, many mistakenly consider him an atheist, even though he was an out spoken defender of the Deistic view of God. Other important founding fathers who espoused Deism were George Washington, Thomas Jefferson, Benjamin Franklin, Ethan Allen, James Madison, and James Monroe.
Fundamentalist Christians are currently working overtime to convince the American public that the founding fathers intended to establish this country on "biblical principles," but history simply does not support their view. The men mentioned above and others who were instrumental in the founding of our nation were in no sense Bible-believing Christians. Thomas Jefferson, in fact, was fiercely anti-cleric. In a letter to Horatio Spafford in 1814, Jefferson said, "In every country and 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. It is easier to acquire wealth and power by this combination than by deserving them, and to effect this, they have perverted the purest religion ever preached to man into mystery and jargon, unintelligible to all mankind, and therefore the safer for their purposes" (George Seldes, The Great Quotations, Secaucus, New Jersey Citadel Press, 1983, p. 371). In a letter to Mrs. Harrison Smith, he wrote, "It is in our lives, and not from our words, that our religion must be read. By the same test the world must judge me. But this does not satisfy the priesthood. They must have a positive, a declared assent to all their interested absurdities. My opinion is that there would never have been an infidel, if there had never been a priest" (August 6, 1816).
