John Chrysostom — as excerpted in the Catena Aurea on John 6:28-34

“(Hom. xlv. 1) Whereas many miracles were performed in Egypt, at the Red Sea, and in the desert, they remembered this one the best of any. Such is the force of appetite. They do not mention this miracle as the work either of God, or of Moses, in order to avoid raising Him on the one hand to an equality with God, or lowering Him on the other by a comparison with Moses; but they take a middle ground, only saying, Our fathers did eat manna in the desert.”
