Catena Aurea · Matthäusevangelium 14
And straightway Jesus constrained his disciples to get into a ship, and to go before him unto the other side, while he sent the multitudes away. And when he had sent the multitudes away, he went up into a mountain apart to pray: and when the evening was come, he was there alone. But the ship was now in the midst of the sea, tossed with waves: for the wind was contrary. And in the fourth watch of the night Jesus went unto them, walking on the sea. And when the disciples saw him walking on the sea, they were troubled, saying, It is a spirit; and they cried out for fear. But straightway Jesus spake unto them, saying, Be of good cheer; it is I; be not afraid. And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water. And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus. But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me. And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt? And when they were come into the ship, the wind ceased. Then they that were in the ship came and worshipped him, saying, Of a truth thou art the Son of God.
Or; That Peter alone out of all the number of those that were in the vessel has courage to answer, and to pray that the Lord would bid him come to Him upon the waters, figures the frowardness of his will in the Lord’s passion, when following after the Lord’s steps he endeavoured to attain to despise death. Buthis fearfulness shews his weakness in his after trial, when through fear of death, he was driven to the necessity of denial. His crying out here is the groaning of his repentance there.
