John Chrysostom
Catena Aurea · Johannesevangelium 6
When Jesus therefore perceived that they would come and take him by force, to make him a king, he departed again into a mountain himself alone. And when even was now come, his disciples went down unto the sea, And entered into a ship, and went over the sea toward Capernaum. And it was now dark, and Jesus was not come to them. And the sea arose by reason of a great wind that blew. So when they had rowed about five and twenty or thirty furlongs, they see Jesus walking on the sea, and drawing nigh unto the ship: and they were afraid. But he saith unto them, It is I; be not afraid. Then they willingly received him into the ship: and immediately the ship was at the land whither they went.
(Hom. xliii. 1) And at last He appears quite unexpectedly: They see Jesus walking upon the sea, drawing nigh. He reappears after His retirement, teaching them what it is to be forsaken, and stirring them to greater love; His reappearance manifesting His power. They were disturbed, were afraid, it is said. Our Lord comforts them: But He saith unto them, It is I, be not afraid.
