A key to understanding the Gospel of John is, in many respects, its prologue; yet questions regarding its origin and background, its structure, use of Greek philosophical terms, and indeed its relationship to the rest of the gospel still remain open. The papers in this volume address each of these questions and were presented at the first meeting of the Colloquium Ioanneum, a group of distinguished international Johannine scholars broadly representing different nationalities, religious traditions and approaches to the gospel. The first part offers differing assessments of the background, literary, and theological elements of the prologue, while the second examines presuppositions, methods, and perspectives involved in philosophical interpretation of the Gospel of John.
