Believing the Real Presence the Only Requirement?

In 'Mere Christianity', C.S. Lewis argues for the existence of God and defends Christian theology. The book is divided into four parts: the first argues for the existence of God based on the 'law of human nature'; the second defends Christian theology, including the 'Liar, lunatic, or Lord' trilemma regarding Jesus Christ; the third explores Christian ethics, including the cardinal and theological virtues; and the fourth discusses the Christian conception of God, particularly the Holy Trinity. Lewis also addresses topics such as free will, morality, sexual ethics, and the institution of marriage. The book is known for its clear and logical presentation of Christian apologetics and has been praised for its straightforward and humorous writing style.

The novel centers around Briony Tallis, a thirteen-year-old girl who, in 1935, witnesses a flirtation between her older sister Cecilia and Robbie Turner, the son of a servant. Briony's incomplete grasp of adult motives and her precocious imagination lead her to make a false accusation that changes all their lives. The story follows the repercussions of this event through World War II and into the late 20th century, as Briony spends her life trying to make amends for her mistake. The novel is a complex exploration of guilt, atonement, and the nature of writing and memory.
