This book, continuing a series of studies on the life and teaching of Jesus Christ, is dedicated to the Sermon on the Mount, the longest of all His speeches given in the Synoptic Gospels. The text of the sermon, containing the quintessence of the moral teaching of Jesus, is considered in the broad context of the subsequent church tradition, in which it has a rich history of interpretation and practical application. Placing the main emphasis on the interpretation of sermons in the works of the ancient Fathers of the Church, the author of the book at the same time often turns to the comments of modern philosophers and theologians.
