DEV113: Mere Christianity - C. S. Lewis

These sources provide an overview of C.S. Lewis’s Mere Christianity, a landmark work of Christian apologetics that argues for the rationality and transformative power of faith. Lewis begins by identifying a universal moral law as evidence for a transcendent Creator, eventually leading readers toward the specific claims of the Gospel. He famously presents the trilemma, asserting that Jesus Christ must be viewed as Lord rather than just a moral teacher, given His divine claims. Central to the text is the distinction between moral improvement and spiritual rebirth, where the goal of the believer is total surrender to become a "little Christ." The passages highlight pride as the ultimate sin and define Christian marriage, forgiveness, and charity as fruits of a supernatural life. Ultimately, the sources depict Christianity not as a set of rules, but as an invitation to share in the eternal life of the Trinity.
