Jer 3:15

“The Lord does not say: I will appoint other good shepherds, to do these things, but I, He says, will do; I will commit my sheep to no one. Be secure, Brothers; you sheep, be secure. ...Here I find all good shepherds in one shepherd. For truly good shepherds are not lacking, but they are in one. There are many who are divided. This one is proclaimed, because unity is commended. Nor indeed are the shepherds now silent, and it is said "shepherd," because the Lord has not found one to whom He might entrust His sheep. But then He commended, because He found Peter. Moreover, even in Peter himself, He commended unity. There were many Apostles, and it is said to one: Feed my sheep. Let it not be that good shepherds are now lacking, let it not be that they are missing from us, let it not be that by His mercy, He does not beget and establish them. Surely, if there are good sheep, there are also good shepherds, for from good sheep come good shepherds. But all good shepherds are in one, they are one. They feed, Christ feeds. For the friends of the bridegroom do not speak their own voice, but they rejoice greatly because of the voice of the bridegroom. Therefore, He Himself feeds, when they feed; and He says: I feed, because His voice is in them, His love is in them. For even Peter himself, to whom He was entrusting His sheep as one to another, He wanted to make one with Himself, and thus to commend the sheep to him, so that he would be the head, he would bear the figure of the body, that is, of the Church, and as if the bridegroom and bride were one in one flesh. Therefore, that He might commend the sheep, what does He first say to him, not as to another he might commend? Peter, do you love me? And he responded: I love you. And again: Do you love me? And he responded: I love you. And thirdly: Do you love me? And he responded: I love you. He affirms love, so that He might strengthen unity.”
