Of all the systems of religion that ever were invented, there is no more derogatory to the Almighty, more unedifying to man, more repugnant to reason, and more contradictory to itself than this thing called Christianity. Too absurd for belief, too impossible to convince, and too inconsistent for practice, it renders the heart torpid or produces only atheists or fanatics. As an engine of power, it serves the purpose of despotism, and as a means of wealth, the avarice of priests, but so far as respects the good of man in general it leads to nothing here or hereafter.
Thomas PaineHuman language is local and changeable, and is therefore incapable of being used as the means of unchangeable and universal information.
Thomas PaineBut there are times when men have serious thoughts, and it is at such times, when they begin to think, that they begin to doubt the truth of the Christian religion; and well they may, for it is too fanciful and too full of conjecture, inconsistency, improbability and irrationality, to afford consolation to the thoughtful man. His reason revolts against his creed. He sees that none of its articles are proved, or can be proved.
Thomas PaineThe danger to which the success of revolutions is most exposed, is that of attempting them before the principles on which they proceed, and the advantages to result from them, are sufficiently seen and understood.
