Introduction
This essay explores C.S. Lewis’ purpose in writing Mere Christianity, a seminal work in Christian apologetics, first published in 1952. Originally delivered as a series of radio talks during World War II, the book aims to present core Christian doctrines to a broad audience, including sceptics and believers alike. The discussion will focus on Lewis’ intentions behind the text, his key arguments regarding the meaning of the universe, and the foundations of Christian belief. Additionally, personal reflections on the relevance of these ideas in today’s context will be provided, highlighting their enduring significance. Through this analysis, the essay seeks to offer a sound understanding of Lewis’ contributions to Christian doctrine while considering their applicability in the modern era.
Lewis’ Purpose in Mere Christianity
C.S. Lewis wrote Mere Christianity with the explicit purpose of defending the rationality of Christian faith and presenting its central tenets in a way accessible to a lay audience. As a converted atheist turned Christian apologist, Lewis aimed to address common objections to faith, particularly from a wartime society grappling with existential questions (Lewis, 1952). His goal was not to advocate for a specific denomination but to outline what he termed “mere” Christianity—the shared beliefs uniting all Christians, such as the existence of God and the divinity of Christ. Lewis sought to demonstrate that Christianity offers a coherent framework for understanding human morality and purpose, using logical arguments rather than relying solely on emotion or tradition. For instance, he begins with the concept of a universal moral law, suggesting that its existence points to a transcendent lawgiver (Lewis, 1952). This approach was designed to engage both believers and sceptics, making faith intellectually credible amidst the uncertainties of the mid-20th century.
The Meaning of the Universe and Christian Belief
Lewis’ exploration of the universe’s meaning in Mere Christianity is closely tied to his theistic worldview. He argues that the universe’s complexity and the existence of moral laws within human consciousness cannot be adequately explained by materialism or chance. Instead, he posits that a purposeful Creator—God—underpins reality, providing a framework for understanding life’s ultimate significance (Lewis, 1952). Furthermore, Lewis contends that Christian belief, rooted in the life and teachings of Jesus Christ, offers a unique resolution to humanity’s moral failings through the concepts of sin, repentance, and redemption. He presents Christ as both fully human and divine, a figure whose sacrifice enables reconciliation between humanity and God. Indeed, Lewis’ famous “trilemma”—that Jesus must be either a liar, a lunatic, or Lord—challenges readers to confront the radical claims of Christianity rather than dismissing them as mere moral teachings (Lewis, 1952). This argument remains a cornerstone of Christian apologetics, reflecting Lewis’ commitment to rational discourse.
Personal Reflection: Lewis’ Points on Morality and Meaning
Reflecting on Lewis’ arguments, I find his reasoning about a universal moral law particularly compelling. The idea that humans inherently recognise right and wrong, despite cultural differences, resonates with my own observations of shared ethical principles across societies. However, I question whether this necessarily points to a divine origin, as secular frameworks might also account for such phenomena through evolutionary or social mechanisms. Nevertheless, Lewis’ clarity in presenting complex theological ideas makes his work accessible, and I believe this approach remains relevant today. In an increasingly pluralistic world, where moral relativism often dominates discourse, Lewis’ emphasis on a common moral foundation encourages dialogue about shared values, even among those who do not accept his theistic conclusions.
Personal Reflection: Relevance in the Modern Context
Lewis’ exploration of the universe’s meaning also holds relevance in contemporary society, where existential questions persist amid scientific advancements and global challenges. His assertion that life’s purpose is found in a relationship with God offers a counter-narrative to materialist worldviews, which some may find unfulfilling. Personally, I appreciate how Lewis’ work invites critical engagement with faith, rather than blind acceptance, which is crucial in an era where religious belief is often scrutinised. For instance, issues like climate change or social inequality could benefit from Lewis’ call to moral accountability, as it encourages individuals to consider their responsibilities beyond self-interest. Therefore, while not all may agree with his conclusions, Lewis’ ideas provide a valuable lens for addressing modern dilemmas through a blend of reason and faith.
Conclusion
In conclusion, C.S. Lewis’ purpose in Mere Christianity was to present a rational defence of core Christian beliefs, making them accessible to a diverse audience during a time of crisis. His arguments about the meaning of the universe and the centrality of Christian doctrine—emphasising a purposeful Creator and Christ’s redemptive role—offer a coherent worldview that challenges materialist perspectives. Personal reflections highlight the enduring relevance of Lewis’ focus on universal morality and existential purpose, particularly in fostering dialogue and accountability in today’s pluralistic and crisis-ridden world. Ultimately, Lewis’ work remains a significant contribution to Christian doctrine, encouraging critical engagement with faith that transcends temporal boundaries.
