"The doctrine that future happiness depends upon belief is monstrous. It is
the infamy of infamies. The notion that faith in Christ is to be rewarded by
an eternity of bliss, while a dependence upon reason, observation and
experience merits everlasting pain, is too absurd for refutation, and can be
relieved only by that unhappy mixture of insanity and ignorance, called
"faith." What man, who ever thinks, can believe that blood can appease God?
And yet, our entire system of religion is based upon that believe. The Jews
pacified Jehovah with the blood of animals, and according to the Christian
system, the blood of Jesus softened the heart of God a little, and rendered
possible the salvation of a fortunate few. It is hard to conceive how the
human mind can give assent to such terrible ideas, or how any sane man can
read the Bible and still believe in the doctrine of inspiration."
[Robert G. Ingersoll, "The Gods", 1872]
