John Chrysostom — as excerpted in the Catena Aurea on Matthew 14:22-33

“Observe how He leads all gradually to that which is above them; He had before rebuked the sea, now He shews forth His power yet more by walking upon the sea, by bidding another to do the same, and by saving him in his peril; therefore they said unto Him, Truly thou art the Son of God, which they had not said above.”
