Gregory the Great — as excerpted in the Catena Aurea on Luke 24:25-35

“(ut sup.) Now behold Christ since He is received through His members, so He seeks His receivers through Himself; for it follows, And he went in with them. They lay out a table, they bring food. And God whom they had not known in the expounding of Scriptures, they knew in the breaking of bread; for it follows, And it came to pass, as he sat at meat with them, he took bread, and blessed it, and brake, and gave it to them. And their eyes were opened, and they knew him.”
