Alcuin of York — as excerpted in the Catena Aurea on John 6:22-27

“To take the passage mystically: on the day following, i. e. after the ascension of Christ, the multitude standing in good works, not lying in worldly pleasures, expects Jesus to come to them. The one ship is the one Church: the other ships which come besides, are the conventicles of heretics, who seek their own, not the things of Jesus Christ. Wherefore He well says, Ye seek Me, because ye did eat of the loaves. (Phil. 2:21)”
