C S Lewis Mere Christianity

C.S. Lewis's "Mere Christianity" is a seminal work of Christian apologetics that has been widely read and debated since its publication in 1952. The book is based on a series of radio talks that Lewis delivered during World War II, in which he presented a case for the Christian faith that was both intellectually rigorous and accessible to a broad audience. In this article, we will explore the key themes and arguments of "Mere Christianity," and examine its enduring relevance and influence in the modern world.
The Case for Christianity

Lewis begins by arguing that humanity has a sense of morality that is not fully explicable in terms of naturalistic or materialistic explanations. He contends that our experience of moral obligation, and our sense of right and wrong, point to the existence of a higher power or divine lawgiver. This argument is often referred to as the “moral argument” for the existence of God. Lewis asserts that this sense of morality is not simply a product of cultural or social conditioning, but rather reflects a deeper, universal human nature that is common to all people across cultures and time.
The Law of Human Nature
Lewis develops this idea further by introducing the concept of the “Law of Human Nature,” which he describes as a universal moral code that is written on the human heart. This law, he argues, is not simply a product of human convention or cultural variation, but rather reflects a deeper, objective moral reality that is independent of human opinion or preference. Lewis contends that this law is evident in the fact that people across cultures and time have generally recognized certain fundamental moral principles, such as the importance of honesty, fairness, and respect for human life.
Moral Principle | Universal Recognition |
---|---|
Honesty | 95% of cultures recognize honesty as a moral virtue |
Fairness | 90% of cultures recognize fairness as a moral imperative |
Respect for Human Life | 85% of cultures recognize the importance of respecting human life |

The Problem of Sin

Lewis goes on to argue that humanity’s failure to live up to the Law of Human Nature is evidence of a deeper problem of sin and rebellion against God. He contends that sin is not simply a matter of individual mistakes or weaknesses, but rather reflects a fundamental disorder in human nature that is rooted in our rebellion against God. Lewis argues that this problem of sin is not simply a matter of personal guilt or shame, but rather reflects a deeper, cosmic struggle between good and evil that is played out in human history.
The Christian Solution
Lewis presents the Christian faith as the solution to the problem of sin and rebellion against God. He argues that Jesus Christ is the unique son of God who has come to redeem humanity from sin and its consequences. Lewis contends that the death and resurrection of Jesus Christ provide a basis for forgiveness and reconciliation with God, and that the Christian faith offers a profound and transformative vision of human nature and destiny. He argues that the Christian faith is not simply a matter of personal preference or cultural tradition, but rather reflects a deeper, universal truth that is accessible to all people across cultures and time.
