This article explores the rich Biblical symbols embedded in C.S. Lewis's The Lion, The Witch, and The Wardrobe, the first published novel of The Chronicles of Narnia series. Through an analysis of key characters, narrative structure, and thematic motifs, the study highlights how Lewis weaves Christian doctrine into the fabric of the novel. Central to this examination is the figure of Aslan, whose sacrificial role mirrors the narrative of Christ's redemption. The article also considers the allegorical significance of themes such as resurrection, temptation, and the struggle between good and evil, showcasing how Lewis uses Narnia as a platform for exploring complex theological concepts. By situating these elements within both the historical context of Lewis's own faith and the broader literary landscape, the article underscores the enduring impact of these symbols on readers' understanding of moral and spiritual truths. Ultimately, it argues that Lewis's integration of Christian symbolism not only enriches the narrative but also invites deeper reflection on faith and redemption in a fantastical context.
