Thomas Jefferson on "the real Anti-Christ"

Thomas Jefferson, denounced as an atheist, was actually a deist who detested organized religion.

Sir, Yours of the 7th instant has been duly received, with the pamphlet inclosed, for which I return you my thanks. Nothing can be more exactly and seriously true than what is there stated; that but a short time elapsed after the death of the great reformer of the Jewish religion, before his principles were departed from by those who professed to be his special servants, and perverted into an engine for enslaving mankind, and aggrandising their oppressors in Church and State; that the purest system of morals ever before preached to man, has been adulterated and sophisticated by artificial constructions, into a mere contrivance to filch wealth and power to themselves; that rational men not being able to swallow their impious heresies, in order to force them down their throats, they raise the hue and cry of infidelity, while themselves are the greatest obstacles to the advancement of the real doctrines of Jesus, and do in fact constitute the real Anti-Christ. - Letter to Samuel Kercheval Monticello, January 19, 1810
