This book is devoted to the study and interpretation of the text of the Apocalypse / Revelation of John the Theologian, the last book of the Bible. The biblical author helps readers go beyond negative stereotypes about the Apocalypse as a “description of catastrophes and the end of the world” and invites them to see the Apocalypse as an organic part of the Bible, bringing readers the bright New Testament message about Jesus Christ and the historical path of the Christian Church. The book provides a full analysis of all chapters of the Apocalypse and consistently substantiates the key thesis - “The Apocalypse is a book of hope.” The author gives examples of vivid interpretations from the ancient church tradition and introduces numerous modern theological interpretations of the Apocalypse. The presentation is based on a thematic principle; many controversial issues that cause controversy among modern readers are discussed. The book combines the popular science genre of a textbook, theological commentary and personal testimony of faith. A systematic, lively presentation makes the book accessible to all those interested. The publishing layout is saved in a4.pdf format.
