John Chrysostom
Catena Aurea · Johannesevangelium 6
Then said they unto him, What shall we do, that we might work the works of God? Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent. They said therefore unto him, What sign shewest thou then, that we may see, and believe thee? what dost thou work? Our fathers did eat manna in the desert; as it is written, He gave them bread from heaven to eat. Then said Jesus unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. For the bread of God is he which cometh down from heaven, and giveth life unto the world. Then said they unto him, Lord, evermore give us this bread.
(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 equalitywith 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.
