Augustine of Hippo
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.
(Tr. xxv. 2) Yet He who feared to be made a king, was a king; not made king by men, (for He ever reigneth with the Father, in that He is the Son of God,) but making men kings: which kingdom of His the Prophets had foretold. Christ by being made man, made the believers in Him Christians, i. e. members of His kingdom, incorporated and purchased by His Word. And this kingdom will be made manifest, after the judgment; when the brightness of His saints shall be revealed. The disciples however, and the multitude who believed on Him, thought that He had come to reign now; and so would have taken Him by force, to make Him a king, wishing to anticipate His time, which He kept secret.
