Augustine of Hippo
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.
(Tr. xxv. 19) See how the twofold resurrection is expressed here. He who cometh to Me, shall forthwith rise again; by becoming humble, and a member of Me. But then He proceeds; But I will raise him up at the last day. To explain the words, All that the Father hath given Me, and, I should lose nothing, He adds; And this is the will of Him that hath 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. Above He said, Whoso heareth My word, and believeth on Him that sent Me: (c. 5:24) now it is, Every one which seeth the Son, and believeth on Him. He does not say, believe on the Father, because it is the same thing to believe on the Father, and on the Son; for as the Father hath life in Himself, even so hath He given to the Son to have life in Himself; and again, That whoso seeth the Son and believeth on Him, should have everlasting life: i. e. by believing, by passing over to life, as at the first resurrection. But this is only the first resurrection, He alludes to the second when He says, And I will raise him up at the last day.
