Catena Aurea by St. Thomas Aguinas
John CHAP. 21
21:15–1715. 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.
16. 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.
17. 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.
THEOPHYLACT. The dinner being ended, He commits to Peter the superintendence over the sheep of the world, not to the others: So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou Me more than these?
AUGUSTINE. Our Lord asked this, knowing it: He knew that Peter not only loved Him, but loved Him more than all the rest.
ALCUIN. He is called Simon, son of John, John being his natural father. But mystically, Simon is obedience, John grace, a name well befitting him who was so obedient to God’s grace, that he loved our Lord more ardently than any of the others. Such virtue arising from divine gift, not mere human will.
AUGUSTINE. 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.
CHRYSOSTOM. (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.
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.
AUGUSTINE. (Tract. cxxii) Well doth He say to Peter, Lovest thou Me (ἀγαπᾶς diligis), and Peter answer, Amo Te (φελῶ amo), and our Lord replies again, Feed My lambs. Whereby, it appears that amor and dilectio are the same thing: especially as our Lord the third time He speaks does not say, Diligis Me, but Amas Me. He saith unto him the third time, Simon, son of Jonas, lovest thou Me? A third time our Lord asks Peter whether he loves Him. Three confessions are made to answer to the three denials; that the tongue might shew as much love as it had fear, and life gained draw out the voice as much as death threatened.
CHRYSOSTOM. (Hom. lxxxviii) A third time He asks the same question, and gives the same command; to shew of what importance He esteems the superintendence of His own sheep, and how He regards it as the greatest proof of love to Him.
THEOPHYLACT. Thence is taken the custom of threefold confession in baptism.
CHRYSOSTOM. (Hom. lxxxviii) The question asked for the third time disturbed him: Peter was grieved because He said unto him the third time, Lovest thou Me? He was afraid perhaps of receiving a reproof again for professing to love more than he did. So he appeals to Christ Himself: And he said unto Him, Lord, Thou knowest all things, i. e. the secrets of the heart, present and to come.
AUGUSTINE. (de Verb. Dom. serm. 50) He was grieved because he was asked so often by Him Who knew what He asked, and gave the answer. He replies therefore from his inmost heart; Thou knowest that I love Thee.
AUGUSTINE. (Tract. cxxiv) He says no more, He only replies what he knew himself; he knew he loved Him; whether any else loved Him he could not tell, as he could not see into another’s heart: (non occ.). Jesus saith unto him, Feed My sheep; as if to say, Be it the office of love to feed the Lord’s flock, as it was the resolution of fear to deny the Shepherd.
THEOPHYLACT. There is a difference perhaps between lambs and sheep. The lambs are those just initiated, the sheep are the perfected.
ALCUIN. To feed the sheep is to support the believers in Christ from falling from the faith, to provide earthly sustenance for those under us, to preach and exemplify withal our preaching by our lives, to resist adversaries, to correct wanderers.
AUGUSTINE. (Tract. cxxiii) They who feed Christ’s sheep, as if they were their own, not Christ’s, shew plainly that they love themselves, not Christ; that they are moved by lust of glory, power, gain, not by the love of obeying, ministering, pleasing God. Let us love therefore, not ourselves, but Him, and in feeding His sheep, seek not our own, but the things which are His. For whoso loveth himself, not God, loveth not himself: man that cannot live of himself, must die by loving himself; and he cannot love himself, who loves himself to his own destruction. Whereas when He by Whom we live is loved, we love ourselves the more, because we do not love ourselves; because we do not love ourselves in order that we may love Him by Whom we live.
AUGUSTINE. (Serm. Pass.) But unfaithful servants arose, who divided Christ’s flock, and handed down the division to their successors: and you hear them say, Those sheep are mine, what seekest thou with my sheep, I will not let thee come to my sheep. If we call our sheep ours, as they call them theirs, Christ hath lost His sheep.
