- "Of all the tyrannies that affect mankind, tyranny in religion is the worst; every other species of tyranny is limited to the world we live in; but this attempts to stride beyond the grave, and seeks to pursue us into eternity."
- "The continually progressive change to which the meaning of words is subject, the want of a universal language which renders translation necessary, the errors to which translations are again subject, the mistakes of copyists and printers, together with the possibility of willful alteration, are themselves evidences that human language, whether in speech or print, cannot be the vehicle of the Word of God."
- "As to the book called the Bible, it is blasphemy to call it the word of God. It is a book of lies and contradictions, and a history of bad times and bad men. There are but a few good characters in the whole book."
