Augustine of Hippo — as excerpted in the Catena Aurea on John 6:28-34

“(Tr. xxv. s. 12) Or thus; Our Lord sets Himself above Moses, who did not dare to say that He gave the meat which perisheth not. The multitude therefore remembering what Moses had done, and wishing for some greater miracle, say, as it were, Thou promisest the meat which perisheth not, and doest not works equal to those Moses did. He gave us not barley loaves, but manna from heaven.”
