From among the detailed debates on New Testament exegesis since 1900, Paul-Gerhard Klumbies identifies three main lines of discourse, bringing into focus the relationship between the ancient and modern worldview and the question of demythologization; the relationship between Judaism and Christianity; as well as the discussion about the historical Jesus and the origins of Christology, including the "Third Quest" , the "New Perspective on Paul" and the "Within Judaism" debates.
