Ah...there is a debate regarding his beliefs and there are many arguments both ways. He was a freethinker is most acceptable and he definitely was not an atheist.
Thomas Jefferson, as we all know, was a skeptic, a man so hostile to Christianity that he scissored from his Bible all references to miracles. He was, as the Freedom From Religion Foundation tells us, "a Deist, opposed to orthodox Christianity and the supernatural."
Or was he? While Jefferson has been lionized by those who seek to drive religion from public life, the true Thomas Jefferson is anything but their friend. He was anything but irreligious, anything but an enemy to Christian faith. Our nation's third president was, in fact, a student of Scripture who attended church regularly, and was an active member of the Anglican Church, where he served on his local vestry. He was married in church, sent his children and a nephew to a Christian school, and gave his money to support many different congregations and Christian causes.
Moreover, his "Notes on Religion," nine documents Jefferson wrote in 1776, are "very orthodox statements about the inspiration of Scripture and Jesus as the Christ," according to Mark Beliles, a Providence Foundation scholar and author of an enlightening essay on Jefferson's religious life.
I can never join Calvin in addressing his god. He was indeed an Atheist, which I can never be; or rather his religion was Daemonism. If ever man worshipped a false god, he did.
-Thomas Jefferson, letter to John Adams, April 11, 1823 |
