In this volume Stanley Porter tackles a variety of important and often highly contentious topics within the Gospel of John as a means of defining and capturing the distinctive Johannine voice. Subjects discussed include John in relation to competing Gospels, the public proclamation of Jesus in John, the sources of John's Gospel, John's prologue, the "I Am" sayings, the notion of truth, the Passover theme, and the ending of the book.

Each chapter, besides surveying representative research, puts forward new and insightful proposals regarding the topics concerned. Porter does not shy away from matters that have often perplexed Johannine scholars, and he confronts some of the viewpoints that have led to confusion in the field. In exploring John's unique perspective and voice, Porter makes a significant contribution to the wider fields of Jesus studies and New Testament investigation.
