In Sunday’s first reading (DT 18:15-20) Moses tells the Jews that God will raise up from among them a prophet to lead them. God will be with them guiding them.
In the selection from Mark’s Gospel, Jesus is shown teaching in the synagogue for the first time, astonishing those listening because He taught with authority and power, not like the Scribes. When an unclean spirit recognizes Him as the holy one of God and asks: “Have you come to destroy us?” Jesus rebukes him sharply: “Be quiet! Come out of the man!” The man convulsed violently and with a loud shriek the unclean spirit left him. All who looked on were amazed. They asked one another,, What does this mean? A completely new teaching in a spirit of authority! From then on his reputation spread throughout the surrounding region of Galilee. This is the beginning of Jesus’ public life in Mark’s Gospel.
I see Jesus as the great emancipator. His first miracle, the most common miracle He performs in Mark’s Gospel is exorcism and healing. This is appropriate because liberation is central to Jesus’ mission. (Workbook for Lectors and Gospel Reader’s and Proclaimers of the Word)

More precisely though actual possession by a spirit entity is what is really being described. “The glory of God is man fully alive” (St Irenaeus)
