During the ages of faith the Church argued, not illogically, that any degree of cruelty towards sinners and heretics was justified, if there was a chance that it could save them, or others, from the eternal torments of hell. Thus, in the name of the religion of love, hundreds of thousands of people were not merely killed but atrociously tortured in ways that made the gas chambers of Beslen seem humane.

There is no ground whatever for the claim, so often made by religious apologists, that these ideals are specifically Christian and originated with Jesus. What were specifically Christian were some of the less enlightened teachings, which have done untold harm. Christians claim that organised Christianity has been a great force for good, but this view can be maintained on one assumption only: that everything good in the Christian era is a result of Christianity and everything bad happened in spite of it.

One of the most persistent fallacies about the Christian Church is that it kept learning alive during the Dark and Middle Ages. What the Church did was to keep learning alive in the monasteries, while preventing the spread of knowledge outside them... Even as late as the beginning of the nineteenth century, however, nine-tenths of Christian Europe was illiterate.

This hideous doctrine of eternal torment after death has probably caused more terror and misery, more cruelty and more violation of natural human sympathy, than any belief in the history of mankind. Yet this doctrine was taught unambiguously by Jesus.

There is no justification for the common claim that Christianity was responsible for the abolition of slavery. The Negro slave trade - a far more infamous practice than slavery in the ancient world - was initiated, carried on and defended by Christian men in Christian countries.

My chief aim was to combat the view that there can be no true morality without supernatural sanctions. So I argued at length that the social, or altruistic, impulses are the real source of morality, and that an ethic based on these impulses has far more claim on our allegiance than an ethic based on obedience to the commands of a God who created tapeworms and cancer-cells.
