John Chrysostom
Catena Aurea · Johannesevangelium 21
So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs. He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep. He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
(Hom. lxxxviii. 1) That which most of all attracts the Divine love is care and love for our neighbour. Our Lord passing by the rest, addresses this command to Peter: he being the chief of the Apostles, the mouth of the disciples, and head of the college. Our Lord remembers no more his sin in denying Him, or brings that as a charge against him, but commits to him at once the superintendence over his brethren. If thou lovest Me, have rule over thy brethren, shew forth that love which thou hast evidenced throughout, and that life which thou saidst thou wouldest lay down for Me, lay down for the sheep.
