Evelyn Underhill's Man and the Supernatural: A Study in Theism (1934) explores the relationship between human experience and divine (supernatural) reality. Underhill emphasizes practical theism, focusing on the human response to the Divine, Christian mysticism, and the awareness of God's real presence in everyday life, rather than merely theoretical theological study. Written against an Anglo-Catholic background, the book emphasizes worship and humble submission as the essence of life. Overall, the book is a guide for readers to understand how finite human life comes into contact with infinite divine reality, demanding an active response of faith and worship.
