[A]ll churches, whether Jewish, Christian or Muslim, are simply human inventions. They use fear to enslave us. They are a monopoly for power and profit. The Age of Reason (1794)
As to the Christian system of faith, it appears to me as a species of atheism; a sort of religious denial of God. It professes to believe in a man rather than in God. It is a compound made up chiefly of man-ism with but little deism, and is as near to atheism as twilight is to darkness. It introduces between man and his Maker an opaque body, which it calls a redeemer[.] The Age of Reason (1794)
