What does Luke 8:27 mean?
Jesus and His disciples have just crossed the Sea of Galilee, surviving a fierce storm to do so (Luke 8:22–25). Seas are symbols of chaos and represent humanity's lack of control over the environment; the storm only serves to emphasize that belief. But Jesus calmed it with a single phrase, leading the disciples to question who He is. Now, they face a man who is possessed by a legion of demons. From a metaphor for evil to evil literally incarnate, Jesus' immense power brings the disciples face-to-face with the mystery of Jesus' identity.Luke describes the man (Luke 8:28–29), then parallels that description after Jesus frees him (Luke 8:35–39). In the beginning, the man has many demons, is naked, and does not live in a house; after, the man is released and clothed (Luke 8:35), and Jesus will tell him to return home (Luke 8:39). Where the demons will force the man to fall before Jesus, shouting (Luke 8:28) and out of control (Luke 8:29), he will later sit quietly and in his right mind at Jesus' feet (Luke 8:35).
This story is also in Matthew and Mark, although each account emphasizes different details. Luke mentions that the man is naked and possessed by multiple demons, but the singular pronoun "me" indicates the demons work in unity (Luke 8:28). Mark seems to suggest there is only one "unclean spirit" (Mark 5:2) but goes on to identify that spirit as "Legion," indicating there are many (Mark 5:9). Matthew notes there are two men (Matthew 8:28); apparently, Mark and Luke focus on the one man who wants to follow Jesus (Mark 5:18–19; Luke 8:38–39). There is no reason to think this man is not a Gentile, but at the end he will beg to join Jesus' disciples (Luke 8:38)
"Tombs" were caves carved into hillsides. Although the very poor sometimes made their homes in empty tombs, this man has a house (Luke 8:39); the demons have overridden the natural human distaste for rot and death.
Some see a parallel between the demoniac and the rebellious people described in Isaiah 65:1–5. In particular, these are people "who sit in tombs, and spend the night in secret places; who eat pig's flesh, and broth of tainted meat" (Isaiah 65:4). Isaiah refers to Israelites, however, while this man is a Gentile.
