This book is a reading of the text of the Gospel of John in light of a tradition of Johannine authorship represented by the Muratorian Fragment, Papias of Hierapolis, and the Anti-Marcionite Prologue, all which are taken to reflect the influence of a common tradition represented by Jerome, Clement of Alexandria, and Victorinus of Pettau. Taken together these suggest that the Gospel of John was the work of the late first- or early second-century John the Presbyter who mediated the tradition of a distinctive group of Johannine disciples among whom Andrew was most important.
