Behind-the-Scenes: Writing about C.S. Lewis and the Bible

May 06, 2026 by Karlissa Koop in Classic Novels & Authors, Author Insights

By Karlissa J

While I was writing To Narnia and Beyond, I ‘tried out’ a variety of content and information that ultimately didn’t make it into the book. At one point, I had a chapter comparing how the four authors – MacDonald, Tolkien, Lewis, and L’Engle – each interacted with the Bible in their storytelling. Here is part of the section that I wrote for C.S. Lewis.

The Lion, the Witch and the Wardrobe was the first of the Narnia books written by C.S. Lewis, and it has been highly regarded for how it poignantly mirrors the death and resurrection story of Jesus.

Though there are other events going on in the tale, at the core of the story is the lion Aslan allowing himself to be bound to the stone table in place of the traitor Edmund, where Aslan dies and then, gloriously, is raised back to life. The story’s connections to the Gospels have been obvious to many (though not all) readers.

However, most of Lewis’ fantasy books aren’t based around Bible stories. In fact, many of Lewis’ works barely seem to mention scripture.

In his books of theology and apologetics, Lewis emphasized the importance of using both our logical capacities and our imaginative capacities to explore our faith. He defended traditional Christian beliefs against those who considered them outdated. And he meditated on the nature of God.

C.S. Lewis was a part of the Anglican church, which is a liturgical-style church where there is regular reading of the scriptures and quotes from the Bible within the service. In the Anglican church I attend, every Sunday there is a reading from the Old Testament, a Psalm is recited as a congregation, there’s a reading from the Epistles or Revelation, and there’s a reading from the Gospels (in addition to sometimes reciting parts of Isaiah or other Bible passages). Though his services may have looked slightly different, Lewis would have been very accustomed to hearing multiple portions of scripture in church.

But despite all of this, Lewis rarely mentioned the Bible in any of his writings. He wrote over twenty books, many of them nonfiction works aimed at Christian instruction, yet his only Bible study book was A Reflection on the Psalms.

In the C.S. Lewis Podcast, Lewis biographer Alister McGrath contemplates this.

“Lewis actually doesn’t look at the Bible all that much,” he notes. Instead, “he more looks along it, or he looks at people who have looked along it, and asks, what is this telling me about myself, the way the world is? Lewis I think is using the Bible, but not perhaps in the way you might expect.” (Note 1.)

Sometimes fantasy authors choose to retell Bible stories. Sometimes they choose to quote passages of scripture. And sometimes, the Bible’s influence on their writings is more subtle, existing as the behind-the-scenes source that helped the author pinpoint who God is and how He interacts with His world.

Since coming up with this now-discarded content, I’ve learned that C.S. Lewis might have had a more complex relationship with the Bible than I ever knew. That is one interesting aspect of research: discovering the depth and nuance in life, and how much you didn’t know! But for now, I’m busy reading xenofiction novels - so I may have to revisit Lewis’ understanding of the Bible some other time…

Behind-the-Scenes: Why I Included L'Engle in To Narnia and Beyond

February 04, 2026 by Karlissa Koop in Sneak Peaks, Classic Novels & Authors, Author Insights

By Karlissa J

 

At one point in my writing of To Narnia and Beyond, I was planning not to include Madeleine L’Engle.

I was still in the process of narrowing down which authors to focus on in my exploration of classic Christian fantasy. I’d decided that only deceased authors would count, as I wanted there to have been enough time to see how their legacy endured beyond them. Three authors were very obviously getting in: everyone knows of J.R.R. Tolkien and C.S. Lewis as pillars of fantasy; and George MacDonald had such a strong impact on Lewis (and on me) that there was no denying his inclusion as well.

But what about Madeleine L’Engle?

She is more recent than the other three: Lewis was the youngest of those men, and she was born on his 20th birthday. Her death occurred in 2007, not quite two decades ago. Her Time Quartet novels are odd, falling somewhere between fantasy and sci-fi. And I found that many readers I spoke to had never heard of her.

So why did I end up featuring her in my book To Narnia and Beyond?

For one, she didn’t stop coming up. It was important to me that each of the authors I included inspired Christians beyond their own generation. What I discovered in L’Engle was that she did just that. One of the people she inspired was painter Makoto Fujimura, whose books on faith and art I have greatly enjoyed. I realised that, even if fewer people have heard of her than Lewis or Tolkien, she has left a creative legacy that continues to inspire.

Second, I couldn’t deny anymore the way her writings had changed me.

Initially, I thought her books were strange. But I found myself contemplating life and my thoughts came to a story she’d told. What does it mean to love your enemy? What does it look like for each creature to submit to being what God called them to be? My children have asked me about baby unicorns, and I’m sure they come from eggs, because L’Engle’s A Swiftly Tilting Planet told me so.

Since I’ve written about her in my book, I have encountered more readers who know of Madeleine L’Engle and have enjoyed her writing. I expect that as I continue to talk to people about classic fantasy novels, I’ll continue to meet those who have been inspired by her.

Is It Time You Read Out of the Silent Planet?

November 29, 2025 by Karlissa Koop in Fantasy Review, Book Reviews, Classic Novels & Authors

By Karlissa J

Have you read C.S. Lewis’ Cosmic Trilogy?

You may or may not be aware, but today – November 29 – is C.S. Lewis Reading Day.

Clive Staples Lewis has served as an entry point to fantasy for many Christian readers. He is also well-respected for his spiritual teaching. But before he ever wrote The Chronicles of Narnia or Mere Christianity, C.S. Lewis pursued the creation of a trilogy in a genre that thrilled him: science fiction. The first book of the trilogy, Out of the Silent Planet, was released in 1938.

Out of the Silent Planet introduces Ransom, a man who finds himself kidnapped and taken on a journey through space to another planet. He escapes his kidnappers and wanders the planet’s wilderness until he encounters a native. Ransom befriends the alien being, and from there, his understanding of the world gradually grows.

I have to admit, this is my kind of story! Exploring an enchanting world, interacting with non-human creatures, and discovering a new language and culture!

Appropriately (or perhaps conveniently), Ransom is a philologist (someone who studies language differences); this provides an excuse for the language barrier to be rather smoothly crossed, and an excuse for Lewis to fixate on unique words and concepts.

Perhaps the lesser fame of this work is, in part, due to the fact that it's not for kids: unlike Narnia, it contains a spattering of mature content, nudity, and mild swearing; nothing obscene, but some Christian readers may find it unexpected. Especially those who assume that Lewis’ fantasy stories were all written for children.

However, if you love fantasy and sci-fi, and want to read more from Lewis, I recommend you pick up Out of the Silent Planet!

Also, if you’re interested in learning more about fantasy novels from Christian authors like C.S. Lewis, you may enjoy my upcoming book, To Narnia and Beyond: Four Christians Who Used Fantasy to Teach Spiritual Truths. You can learn more about it by clicking on the image below!

Nerding Out on C.S. Lewis

September 02, 2025 by Karlissa Koop in Book Reviews, Classic Novels & Authors

By Karlissa J

Clive Staples Lewis: many Christians have read at least a few of his books, we quote him without hesitation, and we value his writings for leading so many skeptics to accept Christianity. But how much do you actually know about “Jack,” as he preferred to be called?

In researching for To Narnia and Beyond, I discovered so much I hadn’t known or even expected. I collected books, read much, and then strived to select highlights for the Lewis chapters in To Narnia and Beyond.

But maybe you want more! Maybe you’re thinking: “I’m a nerd too, and I want to understand C.S. Lewis better!” If that’s the case, this blog post is for you: here are four books I recommend for nerdy readers wanting to learn more about Lewis!

Book One: GEORGE MACDONALD by C.S. Lewis

Let’s start with a book that Lewis wrote himself! In these 365 quotes from George MacDonald selected by C. S. Lewis, it becomes clearer how MacDonald influenced Lewis' spiritual beliefs. For me, it accomplished Lewis' stated goal: "to spread his [MacDonald's] religious teaching".

MacDonald's teachings in this book focus on subjects like nature, possessions, our relationship with Christ, and obedience to God.

I found it worth having a physical copy to write notes in: there are many insightful reflections worth recalling and meditating on.

Book Two: IMAGES OF SALVATION IN THE FICTION OF C.S. LEWIS by Clyde S. Kilby

A short, helpful aid to contemplating Lewis' fiction. Contains a brief overview of each of Lewis' novels (handy, since I have not read The Pilgrim's Regress and have no intention to), followed by several spiritual themes that can be drawn from the novel's story and characters.

Book Three: THE MEDIEVAL MIND OF C.S. LEWIS by Jason M. Baxter

Baxter invites us into some of C. S. Lewis' philosophies and creative choices by revealing the inspiration behind them: quotes and ideas from Lewis' favourite medieval books are paired with instances when Lewis modeled his writing after them. I felt drawn in to the 'magic' of these classics, as Baxter's writing style is very contemplative and welcoming.

Book Four: PLANET NARNIA by Michael Ward

Ward explores how ancient and Medieval astrology - particularly the concept of seven planetary personalities - shows up repeatedly throughout Lewis' writing. The core thesis is built around the Chronicles of Narnia, but there is plenty here diving into the Space Trilogy and Lewis' academic works and poetry as well.

Planet Narnia is at times quite technical, and one-quarter of the book is notes, bibliography, and indexes. This is the volume for nitty-gritty details, while Jason M. Baxter's The Medieval Mind of C.S. Lewis provides a more easy-reading introduction to the general topic of Medieval thinking and Medieval astrology/astronomy in Lewis' writing.

Four Approaches to Writing Christian Fantasy

June 02, 2025 by Karlissa Koop in Thoughts on Fantasy, Author Insights

By Karlissa J

“If a writer’s aim be logical conviction, he must spare no logical pains… where his object is to move by suggestion, to cause to imagine… If there be music in my reader, I would gladly wake it.” George MacDonald, “The Fantastic Imagination”

 

Many people debate over whether The Lord of the Rings should be called a “Christian” book series. Tolkien himself once said his books were religious, but different people have different standards for applying the label “Christian” to a work of art; and The Lord of the Rings is subtle in its use of spiritual themes.

For some readers, the subtlety leaves them more open to learning from the books, and the lessons go deeper. Other readers, however, walk away unsure whether they learned anything, and completely unaware of Tolkien’s Christian faith.

Contrast that with the style of George MacDonald. MacDonald was a preacher, and when he told stories he didn’t stop preaching. His fantasy books and fairytales were also deeply symbolic, so in addition to surface-level teachings there are layers to discover upon rereading.

For some (like Lewis) this makes MacDonald’s fantasies rich, exciting, and memorable. Tolkien, however, came to resent them as being too preachy; and some modern readers will find MacDonald’s florid narrative style and layered symbolism hard to make sense of.

L'Engle’s Time Quartet books are an odd mix of openly Christian and bizarrely unconventional. Some readers are deeply moved and drawn to Jesus by these stories, while other readers come away critiquing her beliefs as unorthodox.

And then there’s Lewis. His Cosmic Trilogy alone is all over the place, from only subtly Christian (Out of the Silent Planet) to deeply theological (Perelandra) to focused on critiquing a particular philosophy (That Hideous Strength). His preachiness varies accordingly.

Which is better: to openly declare a Christian message? To subtly explore a Christian worldview in a tale of good versus evil? To fill a story with much teaching and instruction?

I believe all have their place, because there are a myriad of readers in different stages of their walk with God, coming from a variety of backgrounds, ages, reading skills, and learning styles.

In response to a question about how to include Christian messages in a fantasy book, current fantasy author Wayne Thomas Batson had this to say:

“Your allegory will always be too obvious for some and not enough for others. The big thing is, always respect the story itself. If the message within the allegory is precious and valuable, but the story built around it is superficial, it will fail. Tell a fantastic and meaningful story; respect the genre and the reader, and any allegory within will be that much more powerful.” {See Note}

Each of these four classic authors – George MacDonald, J.R.R. Tolkien, C.S. Lewis, and Madeleine L’Engle – had a different way of telling a fantasy story. I encourage you to try reading a book from all of them! Find out which author or authors you enjoy most and learn from best.
