12. The gospel according to Mark, the canon
In the well-known narration of Stilling the Storm (Mark 4, 35-41) Jesus and his disciples

are in a boat. A storm comes up, and Jesus is sleeping on a cushion. The disciples are afraid and wake Jesus up, who calms the storm down. Mark focuses the attention on Jesus: the disciples became a facade, they are helpless without Jesus.
A different situation: the disciples are important. At three places in the gospel according to Mark Jesus picked out three disciples who were going to accompany him and to witness special events: the Raising of Jairus’ Daughter (5, 37), the Transfiguration (9, 2), and the Temptation of Jesus in Gethsemane (14, 33).
The three disciples Peter, John and James were the leaders of the most important apostle churches, and the three events they witnessed and were to bear witness to in each of their churches were the most important creed of the three apostle churches:
the Raising by Jesus (church of John), the Glorification of Jesus (church of Peter) and the temptation, the human suffering of Jesus (church of James).
