This book engages critically one of the most pervasive sets of assumptions within modern biblical studies: namely, that because John is theological and different from the Synoptics, it cannot be historical - nor does it contribute anything of substance to the quest for the historical Jesus. Part I develops a brief history of the debate. Part II assesses critically the strengths and weaknesses of six planks comprising the foundation for two major platforms. The first involves 'the de-historicization of John', the second 'the de-Johannification of Jesus'. Part III takes on centrally the question of how John's tradition may have developed in ways that are largely autonomous and individuated, but also holding open the possibility of contact with parallel gospel traditions. Part IV develops the particular contributions made by the Synoptics to the historical investigation of Jesus, and likewise those made by the Johannine tradition. Part V then develops an array of implications emerging from the present study, sketching trajectories for further investigation and paths of extended inquiry. While this approach may be mistaken as an appeal for the traditional view or a post-modern exploration, it is neither. It intends to be a critical analysis of the so-called 'critical consensus' on John's historicity and expulsion from historical Jesus resources. This book could contribute to opening a new approach in Johannine and Jesus studies alike.
