Mark 1:21

Capernaum became Jesus’ base of ministry in Galilee (cf. Luke 4:16-31). It stood on the Sea of Galilee’s northwest shore and was the hub of the most populous district in Galilee. Archaeologists have done extensive restoration work there. They have reconstructed a synagogue that stood here in the third and fourth centuries.

The synagogues came into existence during the Babylonian exile. The word originally described a group of people, but it later became associated with the building in which the people met. The word "church" has experienced a similar evolution. Customarily the leaders of a local synagogue would invite recognized visiting teachers to speak to the congregation. Mark referred to Jesus’ teaching ministry frequently, but he did not record much of what Jesus taught. Jesus’ actions were of more interest to him. This seems to reflect the active disposition of Peter who influenced Mark’s writing and perhaps the active character of the Romans for whom Mark wrote.

"What Jesus says discloses his understanding of himself and his purposes. What Jesus does reveals primarily the extent and nature of his authority from God. Both what Jesus does and says determine his values and the dynamics of his relations with other characters. They also show Jesus’ integrity in living up to his values and commitments."
