This book challenges the Christian community to grapple with the ethics of war, which have long been sidestepped or ignored. The author, drawing on their experiences in the first World War, argues that Christian teaching must condemn violence and war, just as it condemns other evils like theft or murder. The author believes that war inevitably involves the sacrifice of human life, the destruction of property, and the erosion of human values, thus violating the teachings of Jesus Christ. To illustrate this, he provides a first-person account of the horrors of war, contrasting sharply with the ideals of Christianity. This book pushes readers to reconsider their views on war, offering an alternative perspective that emphasizes Christian principles of peace, love, and non-violence.
