“I do not believe in the creed professed by the Jewish church, by the Roman church, by the Greek church, by the Turkish church, by the Protestant church, nor by any church that I know of. My own mind is my own church.”
“All national institutions of churches, whether Jewish, Christian or Turkish, appear to me no other than human inventions, set up to terrify and enslave mankind, and monopolize power and profit.”
“Of all the animosities which have existed among mankind, those which are caused by difference of sentiments in religion appear to be the most inveterate and distressing, and ought most to be deprecated. I was in hopes that the enlightened and liberal policy, which has marked the present age, would at least have reconciled Christians of every denomination so far that we should never again see the religious disputes carried to such a pitch as to endanger the peace of society.”
“There is nothing which can better deserve our patronage than the promotion of science and literature. Knowledge is in every country the surest basis of public happiness.”
“The whole history of these books [the Gospels] is so defective and doubtful that it seems vain to attempt minute enquiry into it: and such tricks have been played with their text, and with the texts of other books relating to them, that we have a right, from that cause, to entertain much doubt what parts of them are genuine. In the New Testament there is internal evidence that parts of it have proceeded from an extraordinary man; and that other parts are of the fabric of very inferior minds. It is as easy to separate those parts, as to pick out diamonds from dunghills.”
“Christianity neither is, nor ever was a part of the common law.”
“Ridicule is the only weapon which can be used against unintelligible propositions. Ideas must be distinct before reason can act upon them; and no man ever had a distinct idea of the trinity. It is the mere Abracadabra of the mountebanks calling themselves the priests of Jesus."
“And the day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin will be classed with the fable of the generation of Minerve in the brain of Jupiter. But may we hope that the dawn of reason and freedom of thought in these United States will do away with this artificial scaffolding, and restore to us the primitive and genuine doctrines of this most venerated reformer of human errors."
"It is between fifty and sixty years since I read it [the Apocalypse], and I then considered it merely the ravings of a maniac, no more worthy nor capable of explanation than the incoherencies of our own nightly dreams.”
“As to Jesus of Nazareth, my opinion of whom you particularly desire, I think his system of morals and his religion, as he left them to us, the best the world ever saw or is likely to see; but I apprehend it has received various corrupting changes, and I have, with most of the present dissenters in England, some doubts as to his divinity.”
“The question before the human race is, whether the God of nature shall govern the world by his own laws, or whether priests and kings shall rule it by fictitious miracles?”
“Can a free government possibly exist with the Roman Catholic religion?”
