The document discusses perspectives on Jesus' identity from the Gospel of Mark. It notes that in Mark, Jesus is initially identified as the Son of God, but later this title is only used by supernatural beings, not humans. The only exception is the Roman centurion at the cross, who declares "Truly this man was God's Son." Mark uses this to convey that humans can only recognize Jesus' identity through witnessing his death on the cross. The tearing of the temple curtain at Jesus' death further signifies a change in the relationship between heaven and earth. The document examines how Mark uses characters' recognition of Jesus to teach readers about who he was.
