Benjamin Franklin: Toleration in Old and New England

" If we look back into history for the character of present sects in Christianity, we shall find few that have not in their turns been persecutors, and complainers of persecution. The primitive Christians thought persecution extremely wrong in the Pagans, but practised it on one another. The first Protestants of the Church of England, blamed persecution in the Roman church, but practised it against the Puritans: these found it wrong in the Bishops, but fell into the same practice themselves both here and in New England."

Benjamin Franklin in a letter to Richard Price

"When a Religion is good, I conceive that it will support itself; and, when it cannot support itself, and God does not take care to support, so that its Professors are oblig'd to call for the help of the Civil Power, it is a sign, I apprehend, of its being a bad one."

Benjamin Franklin, in a letter to Richard Price. October 9, 1790.

Benjamin Franklin: His Autobiography

"My parents had early given me religious impressions, and brought me through my childhood piously in the Dissenting way. But I was scarce fifteen, when, after doubting by turns of several points, as I found them disputed in the different books I read, I began to doubt of Revelation itself. Some books against Deism fell into my hands; they were said to be the substance of sermons preached at Boyle’s Lectures. It happened that they wrought an effect on me quite contrary to what was intended by them; for the arguments of the Deists, which were quoted to be refuted, appeared to me much stronger than the refutations; in short, I soon became a thorough Deist."

Benjamin Franklin. (1706–1790). His Autobiography.
