Pierre Bayle (1647-1706) didn't agree with Stillingfleet. He denied knowing any immoral atheists and asked readers of his Historical and Critical Dictionary (1697) to send him any evidence of immoral atheists (Popkin 2003: 293-294). The Dictionary went through several editions in Bayle's lifetime but no examples of immoral atheists were ever produced. In fact, the longest article in the Dictionary is the one on Spinoza, who is identified as an atheist and depicted as one of the most moral men who ever lived. Bayle claimed that a society of atheists could be more moral than a society of Christians. He pointed out that, historically,

Christian societies from ancient times to the present were full of evildoers, corrupt persons, sex maniacs, liars, and cheats....His picture of the religious society of ancient Israel was, in some way, even worse, as depicted in his article on King David. (Popkin 2003: 297)

Of course, there are many modern theists who are sex maniacs, liars, cheats, mass murderers, rapists, sexual abusers of children, robbers of pension funds, and the like. It seems obvious from the factual evidence of more than two millennia that belief in God is neither a necessary nor a sufficient condition for being moral. And, despite the fact that philosophers perpetually dispute just about every thesis on every topic, the great moral thinkers of the world have been secular philosophers such as Confucius, Aristotle, Hume, Bentham/Mill, and Kant, rather than the god-based who seem incapable of producing anything more elegant than a divine command theory.
