The trouble is that the argument of the trilogy is incoherent.
OK, in the trilogy we have this evil church that serves an evil deity. But what’s the point of that? Surely Pullman doesn’t think that the evil that theists do is because an evil deity ordered them to do it. No, theists do evil selfish things because they are mortal men who are evil and selfish. And they imagine that what they are doing is approved by their deity in order to justify their actions. They don’t do evil because they are acting under the orders of an evil diety, rather they create that deity in their own image.
So what exactly does it prove if you show an evil church that does evil in the name of a literally existing evil deity? You’re analogizing to the existing churches that do evil, except postulating that an evil deity is behind it all is missing the point. There is no such evil deity, just human beings. Human souls aren’t enslaved by an evil supernatural organization, rather by other human beings.
So imagining an evil deity is the silliest thing imaginable if you want to explore the question of why human beings do evil. I suppose if you really believed in God, and really thought God was evil, then such a book would make sense. But Pullman doesn’t believe in God, or gods. So what exactly does making up an evil deity that seems to have some points of correspondence to what Christians believe about God prove? It doesn’t prove anything.
I suppose the point is supposed to be that if what Christians really believe about God were true, then God would be evil and Christians are evil for worshipping that evil deity. Except the books are totally ineffective in making this point, because the Magisterium and The Authority aren’t really anything like what real-life Christians think God is like.
To push an analogy, suppose I wanted to write a book showing what an asshole Donald Trump was, and showing what assholes people who look up to Donald Trump are. Something like what Orson Welles did with William Randolph Hearst in “Citizen Kane”. And I create a character Monald Mump that’s a thinly veiled reference to Donald Trump. And to show how evil Monald Mump is, I have him molest children, vivisect puppies, and dump botulism into the water supplies of small towns. Now, have I really created an effective attack on Donald Trump? If I want to show what an asshole Donald Trump is, don’t I have to show him doing the sorts of things Donald Trump actually does that make him an asshole? A person who looks like Donald Trump doing evil things that aren’t anything like the evil things Donald Trump actually does is pointless, if what I want to do is critique Donald Trump and the culture that allows Donald Trump to get away with the evil things he does.
Such a book might make some sort of point, but it isn’t about why Donald Trump is an asshole anymore, and it isn’t about why a culture that allows Donald Trump to get away with his assholery is an asshole culture. The real life Donald Trump isn’t an asshole because he molests children and vivisects puppies, he’s an asshole because he’s a blowhard vulgarian bully.
So, take the scene where Lyra’s in the prison camp for children, and they’re severing the children’s daemons. If found that section frightening and disturbing…not because I thought it was analgous to what the Christian Church does, teaching children nonsense and separating them from their true spiritual selves, but simply because it was horrifying. It’s a great passage, but not because it’s a critique of Christianity, or any sort of religion. It has nothing to do with religion, for crying out loud, and the people doing the severing weren’t doing it for religious reasons, and it didn’t work as an analogy to the indoctrination of children with nonsense, but rather as an analogy to Nazi medical experiments.
