"The greatest of all the reformers of the depraved religion of his own country, was Jesus of Nazareth. Abstracting what is really his from the rubbish in which it is buried, easily distinguished by its lustre from the dross of his biographers, and as separable from that as the diamond from the dunghill. … The establishment of the innocent and genuine character of this benevolent moralist, and the rescuing it from the imputation of imposture, which has resulted from artificial systems, invented by ultra-Christian sects, unauthorized by a single word ever uttered by him, is a most desirable object, and one to which Priestley has successfully devoted his labors and learning. It would in time, it is to be hoped, effect a quiet euthanasia of the heresies of bigotry and fanaticism which have so long triumphed over human reason, and so generally and deeply afflicted mankind; but this work is to be begun by winnowing the grain from the chaff of the historians of his life."

“A free people [claim] their rights, as derived from the laws of nature, and not as the gift of their chief magistrate.”

“Compulsion in religion is distinguished peculiarly from compulsion in every other thing. I may grow rich by art I am compelled to follow, I may recover health by medicines I am compelled to take against my own judgment, but I cannot be saved by a worship I disbelieve & abhor.”

“No freeman shall be debarred the use of arms [within his own lands].”

“Christianity neither is, nor ever was, a part of the common law [this quote is referring to English Common Law].”

“To begin an affair of that kind now, and carry it on so long a time in form, is by no means a proper plan ... whatever assurances I may give her in private of my esteem for her, or whatever assurances I may ask in return from her, depend on it — they must be kept in private. Necessity will oblige me to proceed in a method which is not generally thought fair; that of treating with a ward before obtaining the approbation of her guardian. I say necessity will oblige me to it, because I never can bear to remain in suspense so long a time. If I am to succeed, the sooner I know it, the less uneasiness I shall have to go through. If I am to meet with a disappointment, the sooner I know it, the more of life I shall have to wear it off: and if I do meet with one, I hope in God, and verily believe; it will be the last.”

“It is literally true that the toleration of banks of paper discount costs the United States one-half their war taxes; or, in other words, doubles the expenses of every war. Now think but for a moment, what a change of condition that would be, which should save half our war expenses, require but half the taxes, and enthral us in debt but half the time.”
