This book explores the mysticism of John in its historical context and puts forward evidence that the mysticism developed in this text is the result of the textualization of a dialogue between the Johannine and Thomasine Christians on the subject of soteriology. This book not only sheds new light on the development of Johannine ideology, but also forges a new path in New Testament sociorhetorical criticism, particularly by developing the field of tradition intertexture.
