Whom he named Peter,

And his brother

Andrew,

James,

John,

Philip,

And Bartholomew.”

Σίμωνα, ὃν καὶ ὠνόμασεν, Πέτρον καὶ Ἀνδρέαν τὸν ἀδελφὸν αὐτοῦ, καὶ Ἰάκωβον καὶ Ἰωάνην, καὶ Φίλιππον καὶ Βαρθολομαῖον,

Luke then gave a list of these 12 apostles.  The first six named were Simon (Σίμωνα), whom he renamed Peter (ὃν καὶ ὠνόμασεν, Πέτρον), his brother Andrew (καὶ Ἀνδρέαν τὸν ἀδελφὸν αὐτοῦ), as well as James (καὶ Ἰάκωβον), John (καὶ Ἰωάνην), Philip (καὶ Φίλιππον), and Bartholomew (καὶ Βαρθολομαῖον).  This section about the names of the 12 apostles is similar to Mark, chapter 3:16-19 and Matthew, chapter 10:2-4.  This list can also be compared to the list in the Acts of the Apostles, chapter 1:13.  There are some discrepancies with these names.  First on all the lists was Simon.  Luke said that Jesus named him Peter, not merely known as Peter.  Next Luke had Andrew, the brother of Peter, but he never mentioned him in the call of the first disciples in chapter 5:1-11.  Next were the 2 brothers James and John, who were mentioned earlier.  James was always listed first.  However, they were not called the sons of Zebedee, as they were in the other gospel stories.  Mark had a longer explanation about them, calling them the sons of thunder.  Clearly, these 4 apostles were considered the most important with Peter at the top of this group, while James played an important role also.  The role of Andrew, the brother of Peter, was more ambiguous.  They are no longer called the 12 disciples (δώδεκα μαθητὰς) but the 12 apostles (δὲ δώδεκα ἀποστόλων).  They had changed from being mere followers (μαθητὰς) to now being sent out as apostles (ἀποστόλων).  Matthew had already mentioned, the call of the first 4 disciples in chapter 4:18-22.  Now they became the first 4 named apostles.  Philip and Bartholomew came next as 5 and 6 in all the lists of the apostles, without any other information about them.
