“Not long ago there was a great disaster at sea. A tourist boat, loaded with cars and holidaymakers, had failed to shut its doors properly; the water began to pour in; the boat began to sink, and panic set in. People were screaming as the happy, relaxed atmosphere of the ship turned in minutes into something worse than a horror movie.

All at once one man — not a member of the crew — took charge. In a clear voice he gave orders, telling people what to do. Relief mixed with the panic as people realized someone at least was in charge, and many managed to reach lifeboats they would otherwise have missed in the dark and the rush. The man himself made his way down to the people trapped in the hold. There he formed a human bridge: holding on with one hand to a ladder and with the other to part of the ship that was nearly submerged, he enabled still more to cross to safety. When the nightmare was over, the man himself was found to have drowned. He had literally given his life in using the authority he had assumed — the authority by which many had been saved.

Take that picture to a different sea coast, that of Galilee.” N. T. Wright, Mark for Everyone, vol. 3. (Louisville: Westminster John Knox Press, 2011),
