Bede : But Philip went down to the city of Samaria and preached Christ to them. And he was from among the disseminated ones, who first preached Christ in Samaria, and he began through the deacon, as Christ said to the apostles: And you will be my witnesses in Jerusalem, and in all Judea and Samaria (Acts I). — Retractions on Acts Oecumenius : Not the apostle Philip who is counted among the twelve is this, but one of the seven, the one chosen with Stephen for the administration of the widows. That it is true is clear from here. For of the apostles only those left behind in Jerusalem, while the rest of the disciples were scattered elsewhere, as has already been said; and all were scattered throughout the regions of Judea and Samaria, except the apostles. Among those who were scattered was this Philip, who also instructed Simon in Samaria, and having baptized the Eunuch by a divine oracle, was found by the Spirit of the Lord at Azotus, and then hurried on to Caesarea where he also came to be. For being tried by the persecution against Stephen, and fearing for fear that he share the lot of his partners, he returned home. Moreover, if the one who baptized in Samaria had been one of the apostles, he would have had the authority to bestow the gift of the Spirit, and Peter and John would not have had to come down from Jerusalem to confer the gift of the Spirit upon them. This one therefore baptizes only as a disciple; the apostles perfect the grace, to whom the authority for such a bestowal had been given. [LETTER FROM ISIDORE] — Commentary on Acts
