Augustine of Hippo
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.
(Tr. vii. c. 21) Has this fig tree any meaning? We read of one fig tree which was cursed, because it had only leaves, and no fruit. Again, at the creation, Adam and Eve, after sinning, made themselves aprons of fig leaves. Fig leaves then signify sins; and Nathanael, when he was under the fig tree, was under the shadow of death: so that our Lord seemeth to say, O Israel, whoever of you is without guile, O people of the Jewish faith, before that I called thee by My Apostles, when thou wert as yet under the shadow of death, and sawest Me not, I saw thee.
