This theological study examines the evangelist Mark's view of Jesus' death (Mark's soteriology). The author analyzes how Mark organizes his Gospel material, particularly the Passion and Temptation, to convey the theological meaning behind salvation. It consists of two parts: Part I. The temptation (Mark 1:12-13) and Part II. The passion (Mark 14-16). Part I expresses the author's opinion that Mark views Jesus' temptation in the wilderness as a decisive battle between Jesus and Satan. Unlike Matthew/Luke, Mark focuses not on the details of the temptation but on the fact that Jesus fought and defeated Satan early in His ministry. This victory makes Jesus' subsequent ministry (exorcisms) more of a 'cleansing-up' operation than a major battle. Meanwhile, in Part II, the author focuses on how Mark organizes the narrative of the Passion. He rejects the view that the cross is merely a victory over Satan (the radical Christus Victor view). Instead, he asserts that for Mark, the cross is the atonement for human sin. Mark portrays Jesus' death as the moment that creates a new community (the Church), made up of those whose sins are forgiven. Jesus' suffering is not accidental, but central to God's purpose, as Mark highlights.
