“If you take the cruel passages, the verses that inculcate eternal hatred, verses that writhe and hiss like serpents, you can make a creed that would shock the heart of a hyena.”

What Would You Substitute for the Bible as a Moral Guide? (1900)
Context: I admit that there are many good things in the New Testament, and if we take from that book the dogmas of eternal pain, of infinite revenge, of the atonement, of human sacrifice, of the necessity of shedding blood; if we throw away the doctrine of non-resistance, of loving enemies, the idea that prosperity is the result of wickedness, that poverty is a preparation for Paradise, if we throw all these away and take the good, sensible passages, applicable to conduct, then we can make a fairly good moral guide, — narrow, but moral.
Of course, many important things would be left out. You would have nothing about human rights, nothing in favor of the family, nothing for education, nothing for investigation, for thought and reason, but still you would have a fairly good moral guide. On the other hand, if you would take the foolish passages, the extreme ones, you could make a creed that would satisfy an insane asylum. If you take the cruel passages, the verses that inculcate eternal hatred, verses that writhe and hiss like serpents, you can make a creed that would shock the heart of a hyena. It may be that no book contains better passages than the New Testament, but certainly no book contains worse. Below the blossom of love you find the thorn of hatred; on the lips that kiss, you find the poison of the cobra. The Bible is not a moral guide. Any man who follows faithfully all its teachings is an enemy of society and will probably end his days in a prison or an asylum.
