“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 it admits of no conclusion. Not anything can be studied as a science, without our being in possession of the principles upon which it is founded; and as this is the case with Christian theology, it is therefore the study of nothing.”
[…] “As to the ancient historians, from Herodotus to Tacitus, we credit them as far as they relate things probable and credible, and no further: for if we do, we must believe the two miracles which Tacitus relates were performed by Vespasian, that of curing a lame man, and a blind man, in just the same manner as the same things are told of Jesus Christ by his historians. We must also believe the miracles cited by Josephus, that of the sea of Pamphilia opening to let Alexander and his army pass, as is related of the Red Sea in Exodus. These miracles are quite as well authenticated as the Bible miracles, and yet we do not believe them; consequently the degree of evidence necessary to establish our belief of things naturally incredible, whether in the Bible or elsewhere, is far greater than that which obtains our belief to natural and probable things.”
[…] “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 dishonourable 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 were any such, than that we permitted one such impostor 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.
Whence arose all the horrid assassinations of whole nations of men, women, and infants, with which the Bible is filled; and the bloody persecutions, and tortures unto death and religious wars, that since that time have laid Europe in blood and ashes; whence arose they, but from this impious thing called revealed religion, and this monstrous belief that God has spoken to man? The lies of the Bible have been the cause of the one, and the lies of the Testament of the other.”
