Many of the visions and revelations handed down as having been given by him are spurious. The miracles ascribed to him are all fabrications of Moslem zealots. He expressly and repeatedly disclaimed all miracles excepting the Koran ; which, considering its incomparable merit, and the way in which it had come down to him from heaven, he pronounced the greatest of miracles. And here we must indulge a few observations on this famous document. While zealous Moslems and some of the most learned doctors of the faith draw proofs of its divine origin from the inimitable excellence of its style and composition, and the avowed illiteracy of Mahomet, less devout critics have pronounced it a chaos of beauties and defects; without method or arrangement; full of obscurities, incoherencies, repetitions, false versions of scriptural stories, and direct contradictions. The truth is that the Koran as it now exists is not the same Koran delivered by Mahomet to his disciples, but has undergone many corruptions and interpolations.

Would you say that any one sacred book is superior to all others in the world? ... I say the New Testament, after that, I should place the Koran, which in its moral teachings, is hardly more than a later edition of the New Testament. Then would follow according to my opinion the Old Testament, the Southern Buddhist Tripitaka, the Tao-te-king of Laotze, the Kings of Confucius, the Veda and the Avesta.

Can any rational person believe that the Bible is anything but a human document? We now know pretty well where the various books came from, and about when they were written. We know that they were written by human beings who had no knowledge of science, little knowledge of life, and were influenced by the barbarous morality of primitive times, and were grossly ignorant of most things that men know today.

I must say, it [the Koran] is as toilsome reading as I ever undertook. A wearisome confused jumble, crude, incondite; endless iterations, long-windedness, entanglement; most crude, incondite; — insupportable stupidity, in short! Nothing but a sense of duty could carry any European through the Koran ... It is the confused ferment of a great rude human soul; rude, untutored, that cannot even read; but fervent, earnest, struggling vehemently to utter itself in words ... We said "stupid:" yet natural stupidity is by no means the character of Mahomet's Book; it is natural uncultivation rather. The man has not studied speaking; in the haste and pressure of continual fighting, has not time to mature himself into fit speech ... The man was an uncultured semi-barbarous Son of Nature, much of the Bedouin still clinging to him: we must take him for that. But for a wretched Simulacrum, a hungry Impostor without eyes or heart ... we will not and cannot take him. Sincerity, in all senses, seems to me the merit of the Koran; what had rendered it precious to the wild Arab men ... Curiously, through these incondite masses of tradition, vituperation, complaint, ejaculation in the Koran, a vein of true direct insight, of what we might almost call poetry, is found straggling.

Let’s just grant the possibility that there is a Creator God, who’s omniscient, who occasionally authors books. And he’s gonna give us a book – the most useful book. He’s a loving God, he’s a compassionate God, and he’s gonna give us a guide to life. He’s got a scribe, the scribe’s gonna write it down. What’s gonna be in that book? I mean just think of how good a book would be if it were authored by an omniscient deity. I mean, there is not a single line in the Bible or the Koran that could not have been authored by a first century person. There is not one reference to anything – there are pages and pages about how to sacrifice animals, and keep slaves, and who to kill and why. There’s nothing about electricity, there’s nothing about DNA, there’s nothing about infectious disease, the principles of infectious disease. There’s nothing particularly useful, and there’s a lot of iron age barbarism in there, and superstition. This is not a candidate book.

Adso of Melk: The Koran, the Bible of the infidels, a perverse book …

William of Baskerville: A book containing a wisdom different from ours.

Too great praise challenges attention, and often brings to light a thousand faults that otherwise the general eye would never see. Were we allowed to read the Bible as we do all other books, we would admire its beauties, treasure its worthy thoughts, and account for all its absurd, grotesque and cruel things, by saying that its authors lived in rude, barbaric times. But we are told that it was written by inspired men; that it contains the will of God; that it is perfect, pure, and true in all its parts; the source and standard of all moral and religious truth; that it is the star and anchor of all human hope; the only guide for man, the only torch in Nature's night. These claims are so at variance with every known recorded fact, so palpably absurd, that every free unbiased soul is forced to raise the standard of revolt.

Yet with every allowance, one feels it difficult to see how any mortal ever could consider this Koran as a Book written in Heaven, too good for the Earth; as a well-written book, or indeed as a book at all; and not a bewildered rhapsody; written, so far as writing goes, as badly as almost any book ever was!

Whether the 6-day creation story is a fable or the truth alluding to time dilation in Albert Einstein’s theory of relativity, the Bible and the Quran – sharing the same root as an Abrahamic religion – are undoubtedly amongst the most profound and influential books ever written.

In the spirit of enthusiasm or vanity, the prophet [Muhammad] rests the truth of his mission on the merit of his book; audaciously challenges both men and angels to imitate the beauties of a single page; and presumes to assert that God alone could dictate this incomparable performance. This argument is most powerfully addressed to a devout Arabian, whose mind is attuned to faith and rapture; whose ear is delighted by the music of sounds; and whose ignorance is incapable of comparing the productions of human genius... If the composition of the Koran exceed the faculties of a man to what superior intelligence should we ascribe the Iliad of Homer, or the Philippics of Demosthenes?

For the Bible, despite all its contradictions and absurdities, its barbarisms and obscenities, remains grand and gaudy stuff, and so it deserves careful study and enlightened exposition. It is not only lovely in phrase; it is also rich in ideas, many of them far from foolish. One somehow gathers the notion that it was written from end to end by honest men — inspired, perhaps, but nevertheless honest. When they had anything to say they said it plainly, whether it was counsel that enemies be slain or counsel that enemies be kissed. They knew how to tell a story, and how to sing a song, and how to swathe a dubious argument in specious and disarming words.

The Bible is different from all other books; other books are written by man, but the Bible not only contains the sayings and commandments of God, but was also written entirely under divine inspiration. So we might say that it is God's book, which he gave to man to lead him to everlasting life.

It is claimed that God wrote a book called the Bible, and it is generally admitted that this book is somewhat difficult to understand. As long as the church had all the copies of this book, and the people were not allowed to read it, there was comparatively little heresy in the world; but when it was printed and read, people began honestly to differ as to its meaning. A few were independent and brave enough to give the world their real thoughts, and for the extermination of these men the church used all her power. Protestants and Catholics vied with each other in the work of enslaving the human mind. For ages they were rivals in the infamous effort to rid the earth of honest people.

The Bible was very definitely written by men, and not superior men either; far from it! This is why so much of it can be shown to be historically and scientifically dead wrong about damned-near everything back-to-front. We’re talking about people who believe snakes and donkeys can talk, who believe in incantations, blood sacrifice, ritual spells, enchanted artifacts, pyrotechnic potions, astrology, and the five elements of witchcraft. They thought that if you use a magic wand to sprinkle blood all over someone, it will cure them of leprosy. We’re talking about people who think that rabbits chew cud, and that bats are birds, and whales are fish, and that π is a round number. These folks believed that if you display striped patterns to a pregnant cow, it would bare striped calves. How could anyone say that who knows anything about genetics? Obviously the authors of this book didn’t.
