John Chrysostom
Catena Aurea · Johannesevangelium 6
And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. But I said unto you, That ye also have seen me, and believe not. All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. For I came down from heaven, not to do mine own will, but the will of him that sent me. And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
(Hom. xlv. 2) Our Lord now proceeds to set forth mysteries; and first speaks of His Divinity: And Jesus said unto them, I am the bread of life. He does not say this of His body, for He speaks of that at the end; The bread that I will give you is My flesh. Here He is speaking of His Divinity. The flesh is bread, by virtue of the Word; this bread is heavenly bread, on account of the Spirit which dwelleth in it.
