Augustine of Hippo
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.
While our Lord was being condemned to death, he feared, and denied Him. But by His resurrection Christ implanted love in his heart, and drove away fear. Peter denied, because he feared to die: but when our Lord was risen from the dead, and by His death destroyed death, what should he fear? He saith unto Him, Yea, Lord; Thou knowest that I love Thee. On this confession of his love, our Lord commends His sheep to him: He saith unto him, Feed My lambs: as if there were no way of Peter’s shewing his love for Him, but by being a faithful shepherd, under the chief Shepherd.
