The correspondence between Rudolf Bultmann (1884–1976) and his disciple Ernst Käsemann (1906–1998) spans over half a century (1925–1976) and is of great interest both historically and concerning New Testament research history. It also bears witness to critical theological debates, especially on the historical Jesus, the relation between anthropology and cosmology respectively eschatology and apocalypticism in the theology of Paul, Bultmann’s existential interpretation, the significance of the New Testament canon and the question of a docetist Christology in the gospel of John.
The edition project started in 2009 and will be published at Mohr (Siebeck), Tübingen.
