I find very often that readers of The Chronicles of Narnia, even fans, who complain about the religious aspects of it, have a very, very limited, and more than that, prejudiced understanding of them.
It seems especially that those who read or re-read them at an older age, with full awareness of the existence of these themes, have already made up a very clear idea of them and of how they influence the stories, and it shows.
I mean—there are obvious ones, like the Deeper Magic in The Lion, the Witch and the Wardrobe, which everyone will get, and about which people usually don’t complain, but otherwise it seems that the ideas readers have of the influences and themes are extremely off.
I need to say here, that I don’t claim to have a superior understanding—most things go over my head, I’m often surprised about what I still find, and whenever I read books or articles about Narnia, I am amazed how much there still is to find and to learn about.
But I do understand the basic way in which Christianity and Religion work in Narnia. And it’s not what most non-religious (and even some Christian) readers think it is.
The first thing is: the Narnia books are not missionary work. They are not books that try to convert things to Christianity—only kids who are raised in Christianity or have in some other way studies its basics (in school, for instance) will even figure out some of the parallels, and even that isn’t a given. The books will not in any way make a child after reading think “Oh, boy, I sure need to become a Christian now.” Religion, in that sense, is not even a subject, and only sparsely referenced as a normal everyday thing, just like in most pieces of western media.
The next thing is: these books don’t teach the world view of modern day American alt-right Protestants. A lot of people, especially on the internet, seem to think so, which is rather odd, considering the books were written in the 50s, by an English (Northern Irish, actually) atheist turned Anglican, whose own unusual religious development, and whose (academical) interest in Paganism and other non-Christian religions certainly kept him open-minded in these respects.
And then there’s all that talk about the Problem of Susan, of course, and about how the Scrubbs were actually woke people, and how everything was sexist and all that “because of those evil Xtians who try to convert the children”.
I see so many posts about how people just ignore the religious themes, and how people who like the books despite them, and that’s all fine and well, but they often have no idea what they are. They are not a case of “hurr hurr white old man wrote bad old-fashioned worldview”, they are on an entirely different level, in certain references and images and quotes that they may actually like a lot, and more general in the Fight for Good and everlasting Hope.
And if you get rid of the religious aspects, you get rid of all that you like about Narnia, and be left with only a shallow little bit won’t appeal to you at all, and probably a good deal of what you think is that annoying Christian influence.
