Bede the Venerable — as excerpted in the Catena Aurea on Luke 9:10-17

“Now our Saviour does not create new food for the hungry multitudes, but He took those things which the disciples had and blessed them, since coming in the flesh He preaches nothing else than what had been foretold, but demonstrates the words of prophecy to be pregnant with the mysteries of grace; He looks towards heaven, that thither He may teach us to direct the eye of the mind, there to seek the light of knowledge; He breaks and distributes to the disciples to be placed before the multitude, because He revealed to them the Sacraments of the Law and the Prophets that they might preach them to the world.”
