Reading of Mark 4:33-41
33 With many such parables he spoke the word to them, as they were able to hear it; 34 he did not speak to them without a parable, but privately to his own disciples he explained everything.
35 On that day, when evening had come, he said to them, “Let us go across to the other side.” 36 And leaving the crowd, they took him with them, just as he was, in the boat. And other boats were with him. 37 And a great storm of wind arose, and the waves beat into the boat, so that the boat was already filling. 38 But he was in the stern, asleep on the cushion; and they woke him and said to him, “Teacher, do you not care if we perish?” 39 And he awoke and rebuked the wind, and said to the sea, “Peace! Be still!” And the wind ceased, and there was a great calm. 40 He said to them, “Why are you afraid? Have you no faith?” 41 And they were filled with awe, and said to one another, “Who then is this, that even wind and sea obey him?”
Jesus manifests his divinity by exercising authority over nature. According to the OT, God alone has the power to subdue the raging seas (Ps 89:9; 93:4;107:28-29). This biblical background alarms the disciples and prompts their question, « Who then is this . . . ? » (Mk 4:41).
« The episode at sea signifies the drama of the Christian life. All of God’s children embark with Christ on a life that is full of dangerous storms, especially attacks from evil spirits and temptations of the flesh. We must learn to trust in Christ daily, since he alone can restrain these forces and bring us to the safe harbor of salvation. » – St Augstine, Sermo 51
