Theologie des Neuen Testaments

In terms of its substance, it may [...] be stated without reservation of this work - which represents the sum of Rudolf Bultmann's life's work - that it is a standard work of New Testament, indeed of comprehensive theological scholarship in our century. Its conception enabled its author, with meticulous scholarly precision, to situate the message of the New Testament witnesses within the horizon of the responsibility in faith and thought opened up by the kerygma - a responsibility in which human existence must prove itself in shaping life through the correlation of Christianity and the humanum.
(Otto Merk, translated from the preface to the 9th edition)
