I've never heard a theology graduate complain about God being a bloodthirsty, genocidal baby killing desert deity. Why? Because they're generally not copying and pasting from atheistic websites.
Theological commentator Jonathan Sherwin points out that since there's no way to scientifically attack God, that atheists resort to the same old attacks on God's character:
Leaving behind the intellectual front, those with a particular disdain for Christianity retreated only to launch an offensive on the moral character of God. Instead of talking about such things as beginnings and designers and all the rest of it, now perhaps some of the thrust is towards what sort of a God is there.
Richard Dawkins, the best-selling author known for his articulate attacks on religion – and Christianity in particular – takes special objection to the character of God found in the Old Testament. Dawkins tells us that “[the] God of the Old Testament is arguably the most unpleasant character in all fiction”, before unleashing a torrent of nasty character attributes upon God. Whilst leaving aside claims of the Bible as “fiction” for a later article, the accusation of unpleasantness should be taken very seriously.
Let us be quite clear here, the Bible has some very difficult passages to digest. Many of these are found in the Old Testament and centre on the exploits of Joshua in his handling of the Canaanites.
Cries of ‘Ethnic Cleansing’ and ‘Genocide’ ring out from the towers of atheism. How on earth could you love that same God? How on earth could you say that same God is loving? After all, we rightly condemn the atrocities committed at the hands of the Nazis upon the Jews, or of blood spilled in Rwanda in 1994, so how can the God of the Old Testament not be held to the same standard?
Some of the problematic parts can be found in the book of Joshua. In one such place it is said that Joshua “struck all the land” and “left no survivor.” He is said to have “utterly destroyed all who breathed”. Heavy words. Now to set the scene briefly, we must understand something about Canaanite culture. It was bloodthirsty. Think of a scene from the film 300, but worse. Child sacrifice? Absolutely, it was built in to the heart of the culture. Bestiality? Part of the norm. If we today, part of a nice, civilised, anaesthetised, culture were to be transported back to their day we would most likely break down under sensory overload at the horrors that confronted us.
But surely, you might say, there could be a better way to deal with this than killing everyone. After all, isn’t God supposed to merciful? Well, we read earlier in Genesis that God was patient. In fact, God waited 1,430 years before acting. We also read that this sort of thing wasn’t just a judgement on one people group, and indeed, when the Israelites, God’s own people, got mixed up in some bad things their judgement was equally bad.
Although the Bible never says so, I personally believe that God destroyed Carthage during the Punic wars using the Romans. Although Rome wasn't a perfect society by a long shot, they had a good, solid form of government and they didn't practice human sacrifice. They were trade competitors with Carthage, but as far as they were concerned, it was nothing personal. But the Carthaginians were profligate in their religious practices with ritual prostitution and throwing their infants into the fires of Molech. Atheists, however, are more critical of God than those degenerate peoples he destroyed. And they do it not because they believe in God, but because they believe that if He did exist, His actions would disqualify Him for the job.
But the fallacy of such thinking is obvious. God's critics say if God did exist, He's a monster. But that's a classic non seqitur. Because if God does exist, He knows all things, has all power and knows the hearts of all men. They also ignore the obvious fact that if there is a God, then all men have spirits and continue on after death. If there is no God, then men and animals cease to exist at death and do not live on...in which case this entire debate is meaningless. Nothing has any meaning.
