John Chrysostom
Catena Aurea · Johannesevangelium 1
And the two disciples heard him speak, and they followed Jesus. Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto Him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou? He saith unto them, Come and see. They came and saw where he dwelt, and abode with him that day: for it was about the tenth hour. One of the two which heard John speak, and followed him, was Andrew, Simon Peter’s brother.
(Hom. xviii. 3) One of the two which heard John speak and followed Him was Andrew, Simon Peter’s brother. Why is the other name left out? Some say, because this Evangelist himself was that other. Others, that it was a disciple of no eminence, and that there was no use in telling his name any more than those of the seventy-two, which are omitted.
