-Among the sayings and discourses imputed to him [Jesus] by his biographers, I find many passages of fine imagination, correct morality, and of the most lovely benevolence; and others again of so much ignorance, so much absurdity, so much untruth, charlatanism, and imposture, as to pronounce it impossible that such contradictions should have proceeded from the same being.
-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.
-Christianity neither is, nor ever was a part of the common law.
-In every country and in every age, the priest has been hostile to liberty. He is always in alliance with the despot, abetting his abuses in return for protection to his own.
-If we did a good act merely from love of God and a belief that it is pleasing to Him, whence arises the morality of the Atheist? ...Their virtue, then, must have had some other foundation than the love of God.
-As you say of yourself, I too am an Epicurian. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greece and Rome have left us.
- Priests...dread the advance of science as witches do the approach of daylight and scowl on the fatal harbinger announcing the subversions of the duperies on which they live.
-To talk of immaterial existences is to talk of nothings. To say that the human soul, angels, god, are immaterial, is to say they are nothings, or that there is no god, no angels, no soul. I cannot reason otherwise: but I believe I am supported in my creed of materialism by Locke, Tracy, and Stewart. At what age of the Christian church this heresy of immaterialism, this masked atheism, crept in, I do not know. But heresy it certainly is.
- 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 incoherences of our own nightly dreams.
