The Book of Revelation is one of the most powerful books of the Bible. It was written at the end of the 1st century and is deeply embedded in ancient culture. Martin Karrer's commentary within the renowned series "Evangelical-Catholic Commentary on the New Testament" (EKK) elucidates the apocalyptic imagery as well as the rhetoric of the imperial era and the references to the contexts of that time. He traces the changes in theology throughout its historical impact, such as the concept of the Lamb of God or the proposed view of history. Thus, it offers detailed analyses and information on the many, sometimes controversial, questions of the text and its interpretation.
