Andrei Orlov examines early Christological developments in the light of rabbinic references to the “two powers” in heaven, tracing the impact of this concept through both canonical and non-canonical material. Orlov begins by looking at imagery of the “two powers” in early Jewish literature, in particular the book of Daniel, and in pseudepigraphical writings. He then traces the concept through rabbinic literature and applies this directly to understanding of Christological debates. Orlov finally carries out a close examination of the “two powers” traditions in Christian literature, in particular accounts of the Transfiguration and the Baptism of Jesus. Including a comprehensive bibliography listing texts and translations, and secondary literature, this volume is a key resource in researching the development of Christology. “A very learned volume with a sophisticated grasp of the primary sources … Orlov has provided a thought-provoking thesis.” ― Review of Biblical Literature Andrei Orlov is Professor of Judaism and Christianity in Antiquity at Marquette University, USA.
