The Screwtape Letters - C. S. Lewis

C.S. Lewis’s The Screwtape Letters is a classic work of epistolary fiction that provides a satirical look at spiritual warfare from the perspective of a senior demon. Through correspondence with his nephew, the demon Screwtape outlines strategies to detach a human "patient" from God through subtle distractions, pride, and the distortion of ordinary life. These sources analyze the text from a conservative evangelical viewpoint, emphasizing Lewis’s use of biblical allusions to reinforce the authority of Scripture and the necessity of humility. Major themes include the psychology of temptation, the distinction between the invisible eternal Church and flawed local congregations, and the importance of living in the present rather than being consumed by future anxieties. Ultimately, the materials illustrate how the "gentle slope" of incremental sin is often more dangerous to faith than overt wickedness.
