The contributions to this volume explore the question of what spiritual transformation means for Early Christianity and beyond, with articles ranging from Old Testament wisdom literature to the Dead Sea Scrolls, Graeco-Roman philosophy, the gospels, epistles, and Johannine literature of the New Testament and other Early Christian literature. The contributions provide reflections on the involvement of the self and agency in spiritual transformation and concern diverse anthropological dimensions of mind, emotions, body, and embodiment related to this phenomenon of metamorphosis. The impact of spiritual transformation may relate to a renewal of the mind, to a therapeutics of emotions, and to material dimensions of bodily posture and physiological metaphors expressing spiritual identity.
