Mark 1:23 Commentary | Demonic Interruption
While Jesus is teaching with divine authority in the synagogue in Capernaum, a man with a defiling spirit (i.e., a demon) interrupts. In the New Testament, physical disease and demonic possession are distinguished; the latter requires divine intervention from a higher divine authority (i.e., Jesus). Nonetheless, both Christ’s healings and exorcisms are manifestations of the inbreaking kingdom of God He proclaimed.
