Mere Christianity

Mere Christianity
Based on a series of BBC radio talks delivered during World War II, C. S. Lewis’s Mere Christianity sets out a clear, rational case for the core beliefs of Christianity shared across denominations. In plain, conversational language, Lewis begins with “mere” morality — the idea of a universal moral law pointing to a moral Lawgiver. From this, he argues for God’s existence and then for the person and work of Jesus Christ. The book explores Christian ethics (charity, forgiveness, hope, sexual morality, humility) and explains doctrines such as the Trinity, faith, and the process of becoming “little Christs.” Lewis emphasizes free will, moral choice, and the transformative power of grace, steering clear of sectarian disputes to focus on what unites Christians. Blending reason, metaphor, and vivid analogies, Mere Christianity remains a classic introduction to Christian belief for both skeptics and believers.
