John Chrysostom
Catena Aurea · Johannesevangelium 1
Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile! Nathanael saith unto him, Whence knowest thou me? Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee. Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel. Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? thou shalt see greater things than these. And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man.
(Hom. xx) He asks as man, Jesus answers as God: Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee: not having beheld him as man, but as God discerning him from above. I saw thee, He says, that is, the character of thy life, when thou wast under the fig tree: where the two, Philip and Nathanael, had been talking together alone, nobody seeing them; and on this account it is said, that on seeing him a long way off, He said, Behold an Israelite indeed; whence it appears that this speech was before Philip came near, so that no suspicion could attach to Christ’s testimony. Christ would not say, I am not of Nazareth, as Philip told you, but of Bethlehem; in order to avoid an argument: (ἀμφισβητήσιμον λόγον.) and because it would not have been sufficient proof, had He mentioned it, of His being the Christ. He preferred rather proving this by His having been present at their conversation.
