In this volume, Professor Sauter challenges the kind of eschatology he describes as a 'theology of history,' forcefully represented by Wolfhart Pennenberg and Jurgen Moltmann, He brings this 'theology of history' into conversation with:(1) Albert Schweitzer's 'Konsequente Eschatologie,' that is, eschatology that can only be understood as expectation of imminent events, and (2) 'radical eschatology,' which deals with the foundation of Christian hope or with why we are allowed to hope in the first place. Drawing upon the reformers' (Luther/Calvin) understanding of the biblical term 'promise,' he defines the task of eschatology as establishing the relationship between justification and hope as well as the relationship between God's promise and our future.
