I'm thinking about how differently we do worship than the way that Jesus would have been used to. Mark 1:21 says that he went to a synagogue and taught. Priests served at the temple. Teaching took place at the synagogues.
Are our churches more like the temple or more like synagogues? Is what today we call preaching what Mark meant by teaching? Or, was teaching then like what we mean by teaching now?
How come it was an unclean man who first recognized Jesus? BTW, how common was it for people with unclean spirits to attend the synagogue?
We are told that the people were amazed by his evidencing authority and by his ability to get unclean spirits to obey him. What amazes us today?
