The Gospel of John is a focal point of New Testament exegesis in both methodological and content-related aspects. Jean Zumstein's commentary is committed to the model of 'relecture': the interpretation starts with the existing final text, which it carefully analyzes, while also considering the possibility that the text had a history of development in which various relecture processes led to additions and deepening of the text. In terms of content, the commentary demonstrates the diverse ways in which the understanding of revelation, Christology, and the Passion are closely interconnected in the fourth Gospel. This historically innovative commentary, originally written in French, is now available in German translation and represents an important contribution to the current discussion on the Gospel of John.
