In this article, I argue that ancient expulsion rites and early Jewish scapegoat traditions have influenced the composition of Mk 5.1-20. These rites and traditions inform Mark’s portrayal of Jesus’ transfer of the demons into the swine and their disposal into the sea, which heals the Gentile man. Jesus’ scapegoat-like expulsion of Legion signals God’s banishment of hostile spiritual powers from their positions of authority over the nations and augurs God’s kingdom reign, in which Gentiles are released from bondage to cosmic forces, and their earthly counterparts, cleansed and welcomed into the family of God.
