Bede the Venerable
Catena Aurea · Johannesevangelium 6
The day following, when the people which stood on the other side of the sea saw that there was none other boat there, save that one whereinto his disciples were entered, and that Jesus went not with his disciples into the boat, but that his disciples were gone away alone; (Howbeit there came other boats from Tiberias nigh unto the place where they did eat bread, after that the Lord had given thanks:) When the people therefore saw that Jesus was not there, neither his disciples, they also took shipping, and came to Capernaum, seeking for Jesus. And when they had found him on the other side of the sea, they said unto him, Rabbi, when camest thou hither? Jesus answered them and said, Verily, verily, I say unto you, Ye seek me, not because ye saw the miracles, but because ye did eat of the loaves, and were filled. Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.
They too seek Jesus, not for Jesus’ sake, but for something else, who ask in their prayers not for eternal, but temporal blessings. The mystical meaning is, that the conventicles of heretics are without the company of Christ and His disciples. And other ships coming, is the sudden growth of heresies. By the crowd, which saw that Jesus was not there, or His disciples, are designated those who seeing the errors of heretics, leave them and turn to the true faith.
