Augustine of Hippo
Catena Aurea · Johannesevangelium 6
Verily, verily, I say unto you, He that believeth on me hath everlasting life. I am that bread of life. Your fathers did eat manna in the wilderness, and are dead. This is the bread which cometh down from heaven, that a man may eat thereof, and not die. I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever.
(Tr. xxvi. s. 10.) Our Lord wishes to reveal what He is; Verily, verily, I say unto you, He that believeth on Me, hath everlasting life. As if He said; He that believeth on Me hath Me: but what is it to have Me? It is to have eternal life: for the Word which was in the beginning with God is life eternal, and the life was the light of men. Life underwent death, that life might kill death.
