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 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.

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.

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 rose 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.

The Bible is not a divine revelation from God. It is not inspired; on the contrary, it is a wicked book .... It has been responsible for more suffering and torture than any other volume ever printed……”

It is incumbent on every man who reverences the character of the Creator, and who wishes to lessen the catalogue of artificial miseries, and remove the cause that has sown persecutions thick among mankind, to expel all ideas of revealed religion, as a dangerous heresy and an impious fraud. What is that we have learned from this pretended thing called revealed religion? Nothing that is useful to man, and every thing that is dishonourable to his Maker.

When we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon, than the word of God. It is a history of wickedness, that has served to corrupt and brutalize mankind; and, for my own part, I sincerely detest it, as I detest every thing that is cruel.

It is because of the Biblical curse on man's search for knowledge, which has so paralyzed his mind during the past ages, and its detrimental effect upon progress, that makes the Bible the most wicked, the most detestable, the most pernicious, and the most obnoxious book ever published. ... We will never achieve intellectual liberty until the wickedness of this book has been discarded with the belief in the flatness of the earth.

Had the cruel and murdering orders, with which the Bible is filled, and the numberless torturing executions of men, women, and children, in consequence of those orders, been ascribed to some friend, whose memory you revered, you would have glowed with satisfaction at detecting the falsehood of the charge, and gloried in defending his injured fame. It is because ye are sunk in the cruelty of superstition, or feel no interest in the honour of your Creator, that ye listen to the horrid tales of the Bible, or hear them with callous indifference.

There is no man that believes in revealed religion stronger than I do; but it is not in the reveries of the Old and New Testament, nor of the Koran, that I dignify with that sacred title. That which is revelation to me exists in something which no human mind can invent, no human hand can counterfeit or alter. The word of God is the Creation we behold; and this word of God revealeth to man all that is necessary for him to know of his Creator.

Ours is assuredly the most ridiculous, the most absurd and the most bloody religion which has ever infected this world. Your Majesty will do the human race an eternal service by extirpating this infamous superstition, I do not say among the rabble, who are not worthy of being enlightened and who are apt for every yoke; I say among honest people, among men who think, among those who wish to think. ... My one regret in dying is that I cannot aid you in this noble enterprise, the finest and most respectable which the human mind can point out.

Religious belief is without reason and without dignity, and its record is near-universally dreadful.

Nature never prompted a loving mother to throw her child into the Ganges. Nature never prompted men to exterminate each other for a difference of opinion concerning the baptism of infants. These crimes have been produced by religions filled with all that is illogical, cruel and hideous. These religions were produced for the most part by ignorance, tyranny and hypocrisy. Under the impression that the infinite ruler and creator of the universe had commanded the destruction of heretics and infidels, the church perpetrated all these crimes: Men and women have been burned for thinking there is but one God; that there was none; that the Holy Ghost is younger than God; that God was somewhat older than his son; for insisting that good works will save a man without faith; that faith will do without good works; for declaring that a sweet babe will not be burned eternally, because its parents failed to have its head wet by a priest; for speaking of God as though he had a nose; for denying that Christ was his own father; for contending that three persons, rightly added together, make more than one; for believing in purgatory; for denying the reality of hell; for pretending that priests can forgive sins; for preaching that God is an essence; for denying that witches rode through the air on sticks; for doubting the total depravity of the human heart; for laughing at irresistible grace, predestination and particular redemption; for denying that good bread could be made of the body of a dead man; for pretending that the pope was not managing this world for God, and in the place of God; for disputing the efficacy of a vicarious atonement; for thinking the Virgin Mary was born like other people; for thinking that a man's rib was hardly sufficient to make a good-sized woman; for denying that God used his finger for a pen; for asserting that prayers are not answered, that diseases are not sent to punish unbelief; for denying the authority of the Bible; for having a Bible in their possession; for attending mass, and for refusing to attend; for wearing a surplice; for carrying a cross, and for refusing; for being a Catholic, and for being a Protestant; for being an Episcopalian, a Presbyterian, a Baptist, and for being a Quaker. In short, every virtue has been a crime, and every crime a virtue. The church has burned honesty and rewarded hypocrisy. And all this, because it was commanded by a book — a book that men had been taught implicitly to believe, long before they knew one word that was in it. They had been taught that to doubt the truth of this book — to examine it, even — was a crime of such enormity that it could not be forgiven, either in this world or in the next.

Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible7 is filled, it would be more consistent that we called it the word of a demon, than the Word of God.

Religion has never befriended the cause of humaneness. Its monstrous doctrine of eternal punishment and the torture of the damned underlies much of the barbarity with which man has treated man; and the deep division imagined by the Church between the human being, with his immortal soul, and the soulless "beasts", has been responsible for an incalculable sum of cruelty.
