According to Richard Dawkins:
The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser, a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.
Dawkins evidently spent a fair amount of time with a rhyming dictionary to craft this sentence, and he’s undoubtedly pleased with the result.
Other village atheists like John Loftus, Christopher Hitchens, Hector Avalos, and Robert Ingersoll also accentuate the dastardly character of the Biblical God, as they see it. And this also holds true for Park Avenue atheists like David Lewis and William Rowe.
However, one of the ironies of the moralistic objection to God’s existence is that it renders moot most other arguments against God’s existence.
Atheists attack the argument from prophecy. The argument from miracles. The ontological argument. The cosmological argument. The teleological argument. The argument from consciousness. The argument from religious experience. Biblical archeology. And so on and so forth.
You’d think from all this that they reject God’s existence, either because they think God is inevident, or because the evidence is stacked against him.
But suppose the Lord arranged the stars to spell out “God is a spirit, infinite, eternal, and unchangeable, in his being, wisdom, power, holiness, justice, goodness and truth.”
Would they suddenly bow before the incontrovertible evidence of his existence and become devout believers? Would they love the Lord their God with all their heart, mind, soul, and strength? Would they glorify God and enjoy him forever?
Not if they think such a God is a moral monster. In that case, no amount of evidence, however compelling, would change their jaundiced view of God. For they have already decided that such a God is wholly unworthy of worship.
So the alleged lack of evidence, or counterevidence, is irrelevant to atheism. At least the type of atheism which rails against Biblical theism.
