Christian theology and morality

Setting

On the surface, The Screwtape Letters is set in England during World War II. The main human character, known only as “the Patient,” lives through air raids and faces the possibility of being called up for military service. The true setting of the novel, however, is the unseen spiritual realm. The story unfolds through letters written by the demon Screwtape to his nephew Wormwood, revealing their attempts to corrupt and damn human souls. This hellish perspective provides a unique vantage point on ordinary human life and struggles.

Within this spiritual battleground, much of the action centers on the Patient's everyday life—his home, his church, his interactions with friends, and his romantic interests. The war creates an atmosphere of uncertainty and danger, but the demons are more concerned with the Patient's moral choices and spiritual development than his physical circumstances. Through this lens, Lewis examines both the mundane and profound aspects of a typical British life during wartime.

Characters

• Screwtape: A senior demon who writes letters of advice to his nephew Wormwood. Screwtape is cunning, experienced, and knowledgeable about human nature and temptation. He takes a subtle approach to corrupting humans, preferring gradual influence over dramatic sins. As an administrator in Hell's bureaucracy, Screwtape represents the banality of evil.

• Wormwood: A junior tempter demon and Screwtape's nephew. Wormwood is inexperienced and often makes mistakes in his attempts to corrupt “the Patient.” He is eager to tempt humans into dramatic sins but lacks the subtlety of his uncle. Wormwood's failures ultimately lead to his own destruction.

• The Patient: The unnamed human man that Wormwood is attempting to tempt. He converts to Christianity early in the book, much to the demons' dismay. The Patient goes through various life experiences and temptations throughout the story, ultimately remaining faithful and going to Heaven after dying in the London Blitz.

• The Girl: A Christian woman who becomes romantically involved with the Patient. Her positive influence and devout family help to strengthen the Patient's faith.

• The Enemy: God, referred to as such by the demons. Portrayed as loving humanity and desiring their salvation.

• Our Father Below: Satan, the ruler of Hell. Feared by the demons.

• Slubgob: The principal of the Tempters' Training College for young devils. Mentioned occasionally by Screwtape.

• Toadpipe: Screwtape's secretary, who transcribes his letters.

About the Author

C.S. Lewis (1898-1963) was one of the most imaginative authors and influential Christian scholars of the 20th century. He is best known for The Chronicles of Narnia, a beloved children's fantasy series with strong Christian themes. The seven Narnia books have sold more than 100 million copies worldwide and been adapted into major films. Lewis also wrote nonfiction works dedicated to exploring spiritual questions and making theological concepts accessible, including Mere Christianity, The Screwtape Letters, and The Problem of Pain. His science fiction Space Trilogy and allegorical novel The Great Divorce further showcase his creative storytelling abilities.

Born in Belfast, Lewis became a renowned academic at Oxford and Cambridge, specializing in medieval literature. In addition to his prolific writing career, he was a member of the informal literary group known as the Inklings, which included his close friend J.R.R. Tolkien. Their discussions and mutual encouragement played a key role in the creation of Lewis's Narnia series and Tolkien's The Lord of the Rings trilogy. Lewis's own spiritual journey from atheism to Christianity in his early 30s deeply informed his later writings and apologetics work defending and explaining the Christian faith.

C.S. Lewis's legacy as both a creative storyteller and Christian thinker continues to grow. His works remain widely read and studied, with Lewis societies founded around the world to discuss his ideas. In 2013, he was honored with a memorial in Poets' Corner of Westminster Abbey, cementing his place as one of Britain's most beloved writers.
