Right and Wrong as a Clue to the Meaning of the Universe
In "Mere Christianity," C.S. Lewis embarks on a profound exploration, acting as a guide through the thickets of human morality. He begins by noticing something universal: people quarrel, and within these quarrels lies a tacit appeal to a shared standard of behavior, a Law of Human Nature. Lewis illuminates this law not as a mere suggestion, but as an intrinsic understanding of right and wrong, deeply embedded in our consciousness. He then tackles objections, clarifying that this moral law isn't just herd instinct or social convention, but a real truth, akin to mathematics, that we discover rather than invent. Lewis paints a vivid picture: imagine a world where betrayal is celebrated, where running from battle earns admiration—the very notion is absurd. Yet, Lewis doesn't let us off the hook easily; he confronts us with our consistent failure to live up to this law. Like a physician diagnosing a patient, Lewis points out humanity’s oddity: we are haunted by an ideal of behavior we perpetually fail to meet, creating a tension between what we do and what we know we ought to do. He then considers the universe, presenting two views: the materialist, where existence is a fluke, and the religious, where a conscious mind underlies all. Science, he notes, can only observe; it cannot answer why things exist. But Lewis offers a glimmer of hope: we have "inside information" about humanity. Because we are human, we experience the moral law, a command urging us toward right behavior. This leads Lewis to a crucial juncture: the universe is either a random occurrence or directed by a power. If the latter, that power would influence us internally, guiding our actions. Lewis likens it to opening a packet addressed to ourselves, finding a law we must obey. However, Lewis cautions against a saccharine view of God; this director of the universe is intensely interested in right conduct, but not necessarily indulgent. We are thus caught in a terrible fix, needing goodness but making ourselves its enemies. Lewis concludes by asserting that Christianity, with its call to repentance and promise of forgiveness, only makes sense once we acknowledge this fundamental tension and our inherent need for redemption. It is not a comfortable starting point, but a necessary confrontation with truth.
What Christians Believe
In this chapter of *Mere Christianity*, C.S. Lewis embarks on a profound exploration of core Christian beliefs, navigating the complex terrain between atheism, pantheism, and what he terms "Christianity-and-water"—a diluted, oversimplified faith. Lewis begins by dismantling the notion that Christians must dismiss all other religions as entirely false, suggesting instead that they may contain hints of truth, much like incorrect answers in arithmetic that are closer to the right one. The initial tension arises: if a good God created the world, why is there so much suffering and injustice? Lewis contends that his own sense of injustice, the very basis of his atheistic arguments, implied a standard of justice against which the universe was being judged, thus revealing a hidden assumption of meaning within a seemingly meaningless existence. He cautions against simplistic views, illustrating how reality is often odd and unexpected, much like the seemingly random arrangement of planets in our solar system. Dualism, the belief in two equal powers of good and evil, is examined and ultimately found wanting because evil, to be evil, must corrupt something good, making it a parasite, not an original force. Lewis introduces the concept of a Dark Power, a fallen angel, aligning with the Christian view of a universe at war, occupied by a rebel force; imagine, he suggests, that the world is like enemy-occupied territory and Christianity is the story of how the rightful king has landed in disguise, calling us to a campaign of sabotage. The problem of evil is addressed through the lens of free will: God created beings capable of choosing, knowing that this freedom could lead to wrongdoing, yet deeming it a necessary condition for love and genuine connection. Lewis posits that the essence of sin lies in placing oneself at the center, desiring to be God, an idea that has fueled much of human history's suffering; it's like a car trying to run on the wrong fuel. Finally, Lewis presents the shocking alternative: Jesus's claim to be God is either the ultimate truth, or evidence of lunacy or demonic influence. The central Christian belief, that Christ's death has somehow put us right with God, is explored, and Lewis likens theories about Christ's death to theories about vitamins—helpful explanations, but not the essence itself. Repentance, a crucial element, is described not as a mere act of contrition, but as a complete surrender, a kind of death of the self, requiring God's help, which He provides by becoming man. Lewis concludes by emphasizing the practical implications of sharing in Christ's humility and suffering, stating that this is how we can share in His conquest of death. He highlights baptism, belief, and Holy Communion as the means through which the Christ-life is spread, and that God uses material things like bread and wine to put the new life into us. He urges listeners to join Christ's side now, before God's full, undisguised invasion, when choice will no longer be possible.
Christian Behaviour
In "Christian Behaviour," C.S. Lewis serves as a thoughtful instructor, guiding us through the multifaceted landscape of Christian morality, a terrain often misunderstood as mere restriction. He illuminates that moral rules are not arbitrary prohibitions but rather essential guidelines for the proper functioning of the human machine, preventing breakdowns and friction, much like instructions for operating complex equipment. Lewis divides morality into three critical domains: harmony between individuals, inner harmony within oneself, and the overall purpose of human life, lamenting modern society's overemphasis on social relations while neglecting personal and spiritual alignment. He introduces the Cardinal Virtues—Prudence, Temperance, Justice, and Fortitude—as pivotal hinges upon which civilized life swings, cautioning against the modern distortion of Temperance to mean only abstinence, instead advocating for balance in all pleasures. Lewis confronts the unpopular Christian virtue of chastity, challenging the prevailing lies about sex and emphasizing that the Christian rule is either marriage with complete faithfulness or total abstinence. He dismantles the romanticized notion of 'being in love' as the sole basis for marriage, advocating for a deeper unity rooted in will and habit, strengthened by divine grace. Lewis tackles the daunting duty of forgiving enemies, urging us to start with smaller offenses and to hate the sin but not the sinner, mirroring the self-compassion we extend to ourselves. He identifies Pride as the ultimate vice, a spiritual cancer that eats away at love and contentment, contrasting it with the essential virtue of Humility, which allows us to see God and ourselves clearly. Lewis explores the Theological virtues of Faith, Hope, and Charity, defining Charity as Christian Love—an act of the will—and Hope as a continual looking forward to the eternal world, not as escapism but as a driving force for positive action in the present. He distinguishes two levels of Faith: belief in Christian doctrines despite changing moods, and a higher sense of trusting Christ to make good our deficiencies, emphasizing that while moral effort is essential, it ultimately leads to recognizing our need for divine grace, like a swimmer who must first struggle before surrendering to the water's support. Lewis concludes by suggesting that Christianity, initially appearing as a set of moral rules, ultimately transcends these into a realm of effortless goodness, a state of being so absorbed in the source of light that the mirror no longer sees itself.
Beyond Personality: or First Steps in the Doctrine of the Trinity
In "Beyond Personality," C.S. Lewis addresses the common aversion to theology, likening it to a map of the Atlantic—less thrilling than the real experience, yet essential for navigation. He argues that while direct experiences of God are powerful, theology provides the necessary framework to understand and progress spiritually, cautioning against vague, feel-good religion that leads nowhere. Lewis confronts the popular but superficial view of Christianity as mere moral teaching, asserting that its core lies in the radical claim of becoming sons of God through Christ. He elucidates the distinction between begetting and making: God begets God, as Christ, while He makes humans, who are like statues, resembling but not sharing in divine life or 'Zoe.' The concept of the Trinity emerges as Lewis tackles the idea of a God beyond personality, not less than personal, but super-personal—a dance of three persons in one being, a concept mirrored in the act of prayer where God is both the one prayed to and the inner motivator. He navigates the complexities of God existing outside time, resolving concerns about free will and divine attention. Lewis then explains the eternal relationship between the Father and the Son, emphasizing that love necessitates at least two persons, painting God not as a static entity but as a dynamic activity. Lewis urges us to envision God's love working through us, a spirit that eternally exists between the Father and Son, and highlights the importance of the Christian community as the laboratory for understanding God. He underscores that Christ became human so humans could become sons of God, sharing in divine life through 'good infection,' transforming us from created beings to begotten ones. Lewis stresses that becoming a son of God involves killing the self-centered natural life, likening it to a tin soldier resisting transformation into a real man. He uses the metaphor of Beauty and the Beast to illustrate the act of 'dressing up as Christ' in prayer, not as mere pretense, but as a catalyst for genuine change. Lewis reveals that the Christian journey demands a surrender of the entire self, not just a portion, to Christ, who promises a new self in return, and highlights that it is God who ultimately performs the transformation, with us merely allowing it to happen. He uses the analogy of an egg needing to hatch to be able to fly. Finally, Lewis challenges the expectation that Christians should be universally 'nicer,' clarifying that Christianity aims for a new kind of man, not just improved versions of the old, stressing that God seeks our will, not just our niceness, and that turning to Christ is the only way to find our real selves.
Conclusion
C.S. Lewis's "Mere Christianity" serves as a compelling invitation to examine the moral compass within each of us. The book reveals that our innate sense of right and wrong points to a universal Law of Human Nature, a standard against which we inevitably fall short. This recognition of our moral failings isn't meant to crush us, but to open us to the possibility of redemption. Lewis argues that Christianity isn't merely a set of rules, but a path to transformation, a way to address the inherent tension between our ideals and actions. The journey involves acknowledging a power greater than ourselves, one intensely concerned with right conduct. Ultimately, "Mere Christianity" calls for a surrender of the self, an embrace of humility, and a recognition that true fulfillment lies not in self-centered pursuits, but in Christ. This transformative process allows us to move beyond superficial moralism and experience a deeper, more meaningful connection with the divine, shaping not just our behavior but our very being.
