Ambrose of Milan
Catena Aurea · Lukasevangelium 8
Now it came to pass on a certain day, that he went into a ship with his disciples: and he said unto them, Let us go over unto the other side of the lake. And they launched forth. But as they sailed he fell asleep: and there came down a storm of wind on the lake; and they were filled with water, and were in jeopardy. And they came to him, and awoke him, saying, Master, master, we perish. Then he arose, and rebuked the wind and the raging of the water: and they ceased, and there was a calm. And he said unto them, Where is your faith? And they being afraid wondered, saying one to another, What manner of man is this! for he commandeth even the winds and water, and they obey him.
We are told above, moreover, that He passed the night in prayer. How then does He here fall asleep in a storm? The security of power is expressed, that while all were afraid, He alone lay fearless; but He lay asleep in the body, while in the mind he was in the mystery of divinity. For nothing happens without the Word.
