"TRUTH WILL PREVAIL
OVER FANATICISM"
To The Reverend Jared Sparks
(November 4, 1820)

To The Reverend Jared Sparks

MONTICELLO, NOVEMBER 4, 1820.

SIR, -- YOUR favor of September 18th is just received, with the book accompanying it. Its delay was owing to that of the box of books from Mr. Guegan, in which it was packed. Being just setting out on a journey I have time only to look over the summary of contents. In this I see nothing in which I am likely to differ materially from you. I hold the precepts of Jesus, as delivered by Himself, to be the most pure, benevolent, and sublime which have ever been preached to man. I adhere to the principles of the first age; and consider all subsequent innovations as corruptions of His religion, having no foundation in what came from Him. The metaphysical insanities of Athanasius, of Loyola, and of Calvin, are, to my understanding, mere relapses into polytheism, differing from paganism only by being more unintelligible. The religion of Jesus is founded in the Unity of God, and this principle chiefly, gave it triumph over the rabble of heathen gods then acknowledged. Thinking men of all nations rallied readily to the doctrine of one only God, and embraced it with the pure-morals which Jesus inculcated. If the freedom of religion, guaranteed to us by law in theory, can ever rise in practice under the overbearing inquisition of public opinion, truth will prevail over fanaticism, and the genuine doctrines of Jesus, so long perverted by His pseudo priests, will again be restored to their original purity. This reformation will advance with the other improvements of the human mind, but too late for me to witness it. Accept my thanks for your book, in which I shall read with pleasure your developments of the subject, and with them the assurance of my high respect.
