Last time I checked these are the principles our nation was founded upon:
"I may grow rich by an art I am compelled to follow; I may recover health by medicines I am compelled to take against my own judgment; but I cannot be saved by a worship I disbelieve and abhor. "(Thomas Jefferson, notes for a speech, c. 1776. From Gorton Carruth and Eugene Ehrlich, eds., The Harper Book of American Quotations, New York: Harper & Row, 1988, p. 498.)
Convinced that religious liberty must, most assuredly, be built into the structural frame of the new [state] government, Jefferson proposed this language [for the new Virginia constitution]: "All persons shall have full and free liberty of religious opinion; nor shall any be compelled to frequent or maintain any religious institution": freedom for religion, but also freedom from religion. (Edwin S. Gaustad, Faith of Our Fathers: Religion and the New Nation, San Francisco: Harper & Row, 1987, p. 38. Jefferson proposed his language in 1776.)
Is uniformity attainable? Millions of innocent men, women, and children, since the introduction of Christianity, have been burnt, tortured, fined, imprisoned; yet we have not advanced one 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. (Thomas Jefferson, Notes on Virginia, 1782; from George Seldes, ed., The Great Quotations, Secaucus, New Jersey: Citadel Press, 1983, p. 363.)
