This work addresses a pivotal and controversial area lying at the heart of T. F. Torrance's Christology. Namely, that Jesus Christ assumed fallen and sinful humanity and, living out a sinless life from within our alienated state, healed our human nature. This is a claim that is conceptually basic to Torrance's integration of incarnation and atonement, and thus to his soteriology as a whole. It's pervasive nature and its significance within the overall structure of Torrance's thought is thoroughly and sympathetically set forth. Christ's assumption of sinful flesh is seen to lie underneath a number of disputed areas in Torrance's thought such as the role, or lack thereof, of human responsibility, and the question of universalism. This work not only illuminates, but rigorously examines the claim that "the unassumed is the unhealed."
