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.

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.
