Gustaf Aulén's Christus Victor soteriological/atonement motif is constituted by the central theme of divine victory over the devil. Few scholars discuss at length the significance of Christ's victory over the devil in Aquinas's soteriology. A comparative analysis of the two treatments of Christ's victory over the devil will unveil the role and significance of that victory in Aquinas's soteriology. According to Aquinas, Christ's humanity and all his human actions are the instrumental efficient causes of salvation and, necessarily, his victory over the devil. Therefore, Christ's life prior to his Passion may be examined for evidence of that victory. The most obvious event for such an analysis is Christ's temptations which will offer a unique insight into Aquinas's presentation of Christ's victory over the devil.
