This book identifies the source of the Colossian error as from within Jewish mystical movements and shows how both the theology and practice which is taught in the epistle is to be understood from this context. The book gives a helpful overview of scholarship that has attempted to identify the nature and source of the Colossian error. The book, unlike many others on the topic, is exegetically driven, and will model thorough and careful exegetical practice. The book interacts with extra-Biblical texts which help the reader to understand the mystical contexts of first century Judaism.
