Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 6:45-52

“Then by entering into the ship, the Lord restrained the tempest. For it continues, And he went up unto them into the ship, and the wind ceased. Great indeed is the miracle of our Lord’s walking on the sea, but the tempest and the contrary wind were there as well, to make the miracle greater. For the Apostles, not understanding from the miracle of the five loaves the power of Christ, now more fully knew it from the miracle of the sea. Wherefore it goes on, And they were sore amazed in themselves. For they understood not concerning the loaves.”
