The Screwtape Letters

Imagine opening a book and finding yourself reading someone else's mail. Not just anyone's mail—a senior devil's correspondence with his bumbling nephew, filled with advice on how to corrupt a human soul. That's exactly what C.S. Lewis gives readers in The Screwtape Letters, published in 1942 as World War II raged across Europe.

The book is built around an audacious premise. Screwtape, an experienced tempter who holds a mid-level management position in Hell's bureaucracy, writes a series of letters to his nephew Wormwood. Wormwood is a novice devil fresh out of training college, assigned his first human target—a young British man referred to simply as "the Patient." The young man lives with his aging mother in an unnamed English town, and Wormwood's job is to steer him toward sin, away from God, and ultimately into damnation.

But here's the twist that makes the book so ingenious. Every piece of advice Screwtape gives, every strategy he recommends, every insight into human weakness he shares... it all reveals Christian truth by inversion. When Screwtape warns Wormwood against encouraging the Patient to think too deeply, we learn something about the value of reason. When he celebrates the Patient's spiritual pride, we understand humility better. When he schemes to exploit the Patient's disappointments, we see how God uses those very disappointments for growth.

Lewis opens the book with a crucial warning in his preface. He tells readers he discovered these letters somewhere but won't say how. More importantly, he cautions: "Readers are advised to remember that the devil is a liar. Not everything that Screwtape says should be assumed to be true even from his own angle." Lewis adds that "there is wishful thinking in hell as well as on earth." This warning matters because Screwtape is not an objective narrator. He sees the world through Hell's distorted lens. He believes God's love is a fraud. He thinks selfishness is the only rational approach to existence. He misunderstands joy, dismisses genuine love, and assumes that everyone—even God—operates from self-interest.

The letters follow the Patient through a spiritual journey that spans months or years. He becomes a Christian early in the story, much to Wormwood's frustration. But conversion is just the beginning. The Patient faces a series of tests: disappointment with his fellow churchgoers, temptation from worldly friends, sexual temptation, the stress of war, and the subtle trap of spiritual pride. Through it all, Screwtape offers commentary that's both chilling and darkly funny.

What makes the book so effective is how it uses the devil's perspective to illuminate ordinary human experience. Screwtape describes human beings as creatures who experience "undulation"—natural cycles of spiritual highs and lows. He explains that God allows these troughs because He wants humans to choose faith freely, not be carried along by emotional momentum. He analyzes different types of laughter, identifying which ones serve Hell's purposes. He discusses prayer, sex, marriage, war, and humility—always from the demonic angle, always revealing Christian truth in reverse.

The letters also reveal Hell's internal politics. Screwtape and Wormwood have a relationship built on fear and manipulation, not genuine affection. Screwtape's "love" for his nephew means only that he desires to consume him. Hell operates on the principle that "one thing is not another thing" and "one self is not another self." There is no charity, no generosity, no self-giving love. Every being competes with every other being. This stands in stark contrast to God, whom Screwtape calls "the Enemy," who "really loves the hairless bipeds He has created."

The Patient's story builds toward a climax. He falls in love with a good Christian woman from a genuine Christian family. He serves bravely during air raids despite his fear. And then, in the final letter, the Patient dies during a bombing—his soul going straight to Heaven. Wormwood has failed. Screwtape, furious and hungry, vows to devour his nephew as punishment.

Lewis later added an epilogue called "Screwtape Proposes a Toast," published in 1959. In it, Screwtape addresses graduating tempters, warning them about the dangers of democracy—not democracy as a political system, but the "democratic spirit" that insists everyone is equal in every respect, breeding mediocrity and resentment. This epilogue extends the book's warnings beyond wartime into peacetime, showing that the devil's work never stops.

So here's the question that lingers as we begin this journey through Screwtape's letters: If a senior devil, with centuries of experience corrupting human souls, wrote a manual on how to tempt someone away from God... what would that manual teach us about how to resist?
