On revealed religion

the most detestable wickedness, the most horrid cruelties and the greatest miseries, that have afflicted the human race have had their origin in this thing called revelation, or revealed religion. It has been the most dishonorable belief against the character of the divinity, the most destructive to morality and the peace and happiness of man that ever was propagated since man began to exist. It is better, far better, that we admitted, if it were possible, a thousand devils to roam at large, and to preach publicly the doctrine of devils, if there any such, than we permitted one such imposter and monster as Moses, Joshua, Samuel and the bible prophets, to come with the pretended word of god in his mouth and have credit among us

Thomas Paine, The Age of Reason


On theology

the study of theology as it stands in Christian churches, is the study of nothing; it is founded on nothing, it rests on no principles, it proceeds by no authorities, it has no data, it can demonstrate nothing and admits of no conclusion. Not any thing can be studied as a science without our being in possession of the principles upon which it is founded and as this is not case with Christian theology, it is therefore the study of nothing
