Theophylact of Ohrid
Catena Aurea · Johannesevangelium 1
The day following Jesus would go forth into Galilee, and findeth Philip, and saith unto him, Follow me. Now Philip was of Bethsaida, the city of Andrew and Peter. Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph. And Nathanael said unto him, Can there any good thing come out of Nazareth? Philip saith unto him, Come and see.
For the voice of Christ sounded not like a common voice to some, that is, the faithful, but kindled in their inmost soul the love of Him. Philip having been continually meditating on Christ, and reading the books of Moses, so confidently expected Him, that the instant he saw, he believed. Perhaps too he had heard of Him from Andrew and Peter, coming from the same district; an explanation which the Evangelist seems to hint at, when he adds, Now Philip was of Bethsaida, the city of Andrew and Peter.
