Just then in the synagogue there was one of those men who had an unclean spirit. Unclean Spirititus was going around in those days.
The spirit was really moved by Jesus's teachings and so he cried out, "What do you want with us, Jesus of Nazareth? Have you come to kick some unclean spirit ass? I know who you are. You're that Holy One, right? The Holy One of God? Well, fuck me."
Jesus noted the spirit said "us." He was afraid of this. There was going to be a lot of unclean spirits to rebuke during his ministry. So Jesus sighed and rebuked the unclean spirit by saying, "Shut the hell up already, and get out of that man! That's a bad unclean spirit! Shame on you, unclean spirit!"
Now one of the rules that all unclean spirits must follow is that whenever a Holy One of God commands them to do something, they have to do it. It's part of the code, and unclean spirits always follow the code.
So the unclean spirit vamoosed, but not without putting on a good show first. He made the man - his host - convulse a little and then cry out in a loud voice. Then the spirit came out of him and went off to find another host.
All the people in the synagogue were amazed. They asked each other, "What did we just see? Some kind of new teaching? And with authority! Even the unclean spirits obey him! Are you gonna obey him? I'm not gonna obey him. But did you see that unclean spirit thing he just did? Holy shucking fit."
So Jesus's fame spread throughout Galilee and the surrounding region. His fifteen minutes of fame had started.
Jesus was on the clock.
