Catena Aurea on John 1:43–46: Augustine of Hippo

However you may understand these words, Philip’s answer will suit. You may read it either as affirmatory, Something good can come out of Nazareth; to which the other says, Come and see: or you may read it as a question, implying doubt on Nathanael’s part, Can any good thing come out of Nazareth? Come and see. Since either way of reading agrees equally with what follows, we must inquire the meaning of the passage. Nathanael was well read in the Law, and therefore the word Nazareth (Philip having said that he had found Jesus of Nazareth) immediately raises his hopes, and he exclaims, Something good can come out of Nazareth. He had searched the Scriptures, and knew, what the Scribes and Pharisees could not, that the Saviour was to be expected thence.
