Mere Christianity

C.S. Lewis's Mere Christianity is a compilation of radio talks, later published in book form, that explores the common ground of Christian belief. The book is divided into four sections: one outlining the existence of a moral law, another explaining core Christian doctrines, a third focusing on Christian behaviour, and a final part examining the Trinity. Lewis aims to present a simplified, accessible understanding of Christianity, avoiding divisive theological debates and emphasizing practical application. He argues that understanding the moral law and our failure to uphold it leads to a recognition of our need for redemption. The text also explores related concepts like free will, repentance, and the nature of God.
