John Chrysostom
Catena Aurea · Johannesevangelium 6
The Jews then murmured at him, because he said, I am the bread which came down from heaven. And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven? Jesus therefore answered and said unto them, Murmur not among yourselves. No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day. It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me. Not that any man hath seen the Father, save he which is of God, he hath seen the Father.
(Hom. xlvi. 1) The Jews, so long as they thought to get food for their carnal eating, had no misgivings; but when this hope was taken away, then, we read, the Jews murmured at Him because He said, I am the bread which came down from heaven. This was only a pretence. The real cause of their complaint was that they were disappointed in their expectation of a bodily feast. As yet however they reverenced Him, for His miracle; and only expressed their discontent by murmurs. What these were we read next: And they said, Is not this Jesus, the Son of Joseph, whose father and mother we know? how is it then that He saith, I came down from heaven?
