Why did I subject myself to this?
Most fundamentally, Copan starts with the following assumptions: God is kind and severe (just), the bible is inerrant and univocal, so whatever the Bible depicts God as doing or commanding will either express his kindness or justice.
Now, here is the problem: nothing, and I mean absolutely NOTHING, could count as evidence against Copan's thesis. If commands and actions are unjust, cruel, bullying, sadistic, and pathologically evil? Well, automatically, this is simply the wrath of God; God is a God of justice! That is the severity of God! End of story (though sometimes he tries to downplay it--it wasn't as bad as it seems, or is better than Israel's neighbors' ethics).
If Moses had said, "Fathers, God commands you to rape your daughters, mutilate them, and then eat them, if they complain about making you dinner." Copen wouldn't bat an eye; he would be like, "God is a God of justice and severity; if God commands it, it is just and holy, and it is not as bad as it looks anyhow--some hyperbole going on here, and we don't have any record of Jews actually obeying the command. So yes, only Marcionite-like inside critics would have an issue with this."
It would be impossible to get anywhere with Copan, as nothing could count as evidence of injustice, since either he would downplay the evil or simply call it justice and point out how (what almost everyone considers evil) actually aligns with Jesus.
Copan be like, "The God of the old is the same as the new": Jesus is the perfect revelation of God, and yes, Jesus is like, Let the little children come to me. For such is the kingdom of heaven, and love your enemies, forgive, do good, etc... Oh, and Jesus also really liked Moses... not a jot or tittle of what he said is to be annulled (unless you wanna be least in the Kingdom of God).
Wonderful, we now know what God is like. So let's see this demonstrated in the Old Testament.
Amalakites attack Israel, Moses is like "take offense, hold a grudge (pass the hate on to your children's children) until you are established in the land, and then kill them all." 400 years later, Samual tells Saul, "because the Amalekites attacked Israel, you are to go kill every baby, child, woman, and man, and all the animals." Copan utterly ignores the WARRANT for the command.
So what does Forgiveness mean? Well, it means holding a murderous grudge, passing on this hate to the next generation, and having them pass it on to the next generation (they were like Nazis, after all), for hundreds of years, until you can hyperbolically kill them all. (This is also what justice looks like, God is a God of severity, after all! Jesus cleaned out the temple and would cast Jezebel on a sick bed!)
Loving children? It means hacking them to pieces and dashing their brains out, for something their ancestors did 400 years ago. No worries, though, God's severity flows from his love. Think October 7th in Israel, but on a massive scale--Oh, the gloriously pure and just action of God! Oh how blessed were those who got to slice open the pregnant women's bellies and see both mother and child killed! Oh, but it was just hyperbole, even though God supposedly said kill every woman and child, and the text says they killed every woman and child, maybe not ALL of the babies were killed. So don't worry about it! It wasn't genocide!
Copan would make a great apologist for Stalin or Hitler. The same approach could be used. Let's take Stalin, okay, Copan be like, Stalin is perfectly good and just. Everything Stalin did flowed from love. Then he points to Stalin, saying he was good and just, and he finds others who praise Stalin's character. Now he writes against those outside and inside critics, who bring up problematic things Stalin did and commanded; He shows that dealing with these critics is easy peasy! Is Stalin both Kind and Severe? yes! Staving millions of Ukrainians to death? Well, the strawmenners who bring this up just want to spew anti-Stalin propaganda and leave out all the good Stalin did, oh.. it really happened? Well, the Ukrainians deserved it--Stalin is just, also, 14,000,000... that is hyperbole! Oh, and this action flowed from love! Stalin was not a Vindictive Bully! And literally NOTHING Stalin did could count as evidence for this, since literally EVERYTHING Stalin did that you are uncomfortable with can be rationalized as "justice" and "loving", oh praise Stalin.
I will grant that Copan succeeds in showing that the deity expressed in Matthew and Revelation is just as violent and evil according to most ethical evaluations (and thus holy and just, according to Copan). Yes, there is no difference between the God of the old and the God of the new (if Matt and Rev are used), both are vindictive bullies with an utter contempt for human life--both are beyond good and evil, as no moral reasoning is to apply. Might equals right, human dignity and value repudiated.
Anyhow, since some authors in the New Testament had repugnant conceptions of God, then it does not work to simply say that as a WHOLE, the New Testament presents a better conception of God. Revelation presents Jesus as being infinitely WORSE than every dictator (Antiochus Epiphanies, Nero, Genghis Khan, Stalin, Mao, Hitler, Pol Pot...) combined, so arguably, since Revelation was tragically included in the canon, the "God" of the New Testament is even better captured by the pithy Dawkins quote which Copan began with.
So again, Dawkins wrote "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." For Copan, this is the God of the New Testament, too! This is Jesus (just not in fiction but in reality!) Yay!!!. But... for Copan, we err in saying any of this if we are saying these descriptions are negative. All of these things, when illustrated in scripture, are simply the loving and just severity of God, and are never as bad as they appear.
Copan and adventures in missing the point.
Dear Copan, with the flood, bringing up the grief of God does nothing to address what is the problem. Let's think of an example. The father of a farm with lots of animals has 12 children. 6 of them are really bad, in fact, so bad that one of the brothers actually tortures and kills his younger sister. The father is SOO grieved by this violence! It breaks his heart, so he goes to the local dam, blows it up, and drowns all of the animals and all of his children (including the baby and toddler). Now, should I have a problem with his method of "justice"? Is the fact that he was sad when he had everyone killed and all the animals killed really solve the problem?
Like seriously, Copan, I mean, what better way to say "I don't like violence" than by violently killing EVERYONE! What better why say it makes me sad than to commit worldwide genocide? What better way to say justice is to be proportional, and I value life? Again, what about all the fetuses developing in the mother's womb? What better way to express how pro-life He is than causing worldwide abortions! Oh, the glorious severity of God!
Or with Passover, it is simply poetic justice; Pharaoh killed the Hebrews' firstborn, so God killed their firstborn. Uh... okay, so let me get this straight, suppose my Neighbor Bob was drunk, he runs over my daughter. This gives me the right to go to his house, tie up his three-year-old daughter, and run her over with my truck! Yeah, that is how justice works! For Copan, clearly, it is.
My gosh... this book is so unspeakably horrible.
The only redeemable point was that he was able to attribute the command to slaughter all the Midianite women and take their virgin daughters as booty to Moses rather than God. Mind-blowing and very unlike Copan.
Of course, he does try to spin the Bible as so noble, saying these virgin girls were not raped! I mean, think about it, here we have a girl, she just watched Hebrew men hack to pieces her mother, father, and brothers, and now the man who just murdered her family wants to make her one of his wives! I mean, how noble, God even legislated a little time for her to grieve her family! Oh, and I am sure she consented to marry this man who murdered her family! I am sure once he has sex with her, it will be consensual. I mean, this wasn't rape at all! And it just beautifully shows how much God cared about these virgin girls who were given out as booty to the men who butchered their loved ones. Oh, the kindness of Copan's God!!!!
