Mere Christianity

Religion and spirituality

Print length: 191 pagesSimon & Schuster, 1996

Description

Adapted from C. S. Lewis’s popular BBC radio talks of the 1940s, Mere Christianity presents a defense of Christianity as a shared core faith extending beyond any single denomination. Lewis argues for God’s existence, discusses the Christian understanding of God, and defends central theological claims. One notable argument considers whether Jesus should be understood as a liar, a madman, or Lord. The book also examines Christian ethics, including both cardinal and theological virtues. Developed from informal broadcasts that prompted strong public responses and further question-and-answer talks, it brings questions of doctrine, conduct, and faith together.

About C. S. Lewis

C. S. Lewis was a British literary scholar, novelist, and Anglican lay theologian who worked across children’s fantasy, satire, and Christian apologetics. His writing favors direct, conversational prose and clear structures that turn theological questions into stories, arguments, or comic reversals. He repeatedly examines temptation, moral choice, repentance, sacrifice, and faith, often by placing abstract claims inside ordinary decisions. In The Chronicles of Narnia, children cross from familiar settings into a world of talking animals, contested kingdoms, and mythic creatures. The adventures move briskly through quests and battles, while Christian imagery is carried by character, action, and the recurring presence of Aslan. The Screwtape Letters uses one-sided correspondence between devils, requiring readers to reverse Screwtape’s advice and infer the human drama it distorts. Mere Christianity takes the opposite route. Adapted from radio talks, it develops a plainspoken defense of shared Christian belief through sustained argument and practical discussion of conduct.
