You are actually claiming Jefferson as a christian in favor of creating a christian nation? lol

The Christian Nation Myth
"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)."
"Jefferson didn't just reject the Christian belief that the Bible was "the inspired word of God"; he rejected the Christian system too. In Notes on the State of Virginia, he said of this religion, "There is not one redeeming feature in our superstition of Christianity. It has made one half the world fools, and the other half hypocrites" (quoted by newspaper columnist William Edelen, "Politics and Religious Illiteracy," Truth Seeker, Vol. 121, No. 3, p. 33)."
Here are more quotes by Jefferson:
"Millions of innocent men, women and children, since the introduction of Christianity, have been burnt, tortured, fined, imprisoned; yet we have not advanced an inch towards uniformity. What has been the effect of coercion? To make one half the world fools, and the other half hypocrites. To support roguery and error all over the earth." - "Notes on Virginia"
"Shake off all the fears of servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call on her tribunal for every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason than that of blindfolded fear. - letter to Peter Carr, Aug. 10, 1787
"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 political as well as religious leaders will always avail themselves for their own purpose." - to Baron von Humboldt, 1813
.
"I have recently been examining all the known superstitions of the world, and do not find in our particular superstition (Christianity) one redeeming feature. They are all alike founded on fables and mythology."
"No man shall be compelled to frequent or support any religious worship, place, or ministry whatsoever." -Virginia Act for Religious Freedom
At any rate, the SCOTUS has consistently ruled that the separation of church and state is constitutional and valid.
