Augustine of Hippo
Catena Aurea · Lukasevangelium 6
And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God. And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles; Simon, (whom he also named Peter,) and Andrew his brother, James and John, Philip and Bartholomew, Matthew and Thomas, James the son of Alphæus, and Simon called Zelotes, And Judas the brother of James, and Judas Iscariot, which also was the traitor.
(de Con. Ev. lib. ii. c. 30.) With respect to the name of Judas the brother of James, Luke seems to differ from Matthew, who calls him Thaddæus. But what prevented a man from being called by two or three names? Judas the traitor is chosen, not unwittingly but knowingly, for Christ had indeed taken to Himself the weakness of man, and therefore refused not even this share of human infirmity. He was willing to be betrayed by His own Apostle, that thou when betrayed by thy friend mayest bear calmly thy mistaken judgment, thy kindness thrown away.
