Hofmann, H.-U.: Luther und die Johannes-Apokalypse: Dargestellt im Rahmen der Auslegungsgeschichte des letzten Buches der Bibel und im Zusammenhang der theologischen Entwicklung des Reformators. (BGBE 24). Tübingen: J.C.B. Mohr (Paul Siebeck), 1982. In print.
This book is a rather extensive and detailed dissertational study (Habilitationsschrift) of Luther’s use of the Book of Revelation.
Although Luther’s view on Revelation is often mentioned, few have read more than Luther’s words on Revelation in his preface to his bible translation. Hofmann has investigated the actual uses of Revelation and located them into the history of interpretation and into the development of Luther’s theology.
This book should certainly be consulted with regard to Luther’s understanding (or use) of Revelation.
