Theophylact of Ohrid
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.
(in loc.) Observe then, that it was upon those who followed Him, that our Lord turned His face and looked upon them. Unless thou by thy good works follow Him, thou shalt never be permitted to see His face, or enter into His dwelling.
