John Chrysostom
Catena Aurea · Johannesevangelium 20
And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you, Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God. Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed. And many other signs truly did Jesus in the presence of his disciples, which are not written in this book: But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name. Jesus saith unto him, Because thou hast seen Me, thou hast believed.
(Hom. lxxxvii) John having related less than the other Evangelists, adds, And many other signs truly did Jesus in the presence of His disciples, which are not written in this book. Yet neither did the others relate all, but only what was sufficient for the purpose of convincing men. He probably here refers to the miracles which our Lord did after His resurrection, and therefore says, In the presence of His disciples, and they being the only persons with whom He conversed after His resurrection. Then to let you understand, that the miracles were not done for the sake of the disciples only, He adds, But these are written, that ye might believe that Jesus is the Christ, the Son of God; addressing Himself to mankind generally. And, this belief, he then says, profits ourselves, not Him in Whom we believe. And that believing ye might have life through His name, i. e. through Jesus, which is life.
