There are five major ways of knowing this from Scripture:
I. In Luke 22:24-32, Jesus tells the Apostle which of them is the greatest, and what it means to be the greatest:
24 A dispute also arose among them as to which of them was considered to be greatest. 25 Jesus said to them, âThe kings of the Gentiles lord it over them; and those who exercise authority over them call themselves Benefactors. 26 But you are not to be like that. Instead, the greatest among you should be like the youngest, and the one who rules like the one who serves. 27 For who is greater, the one who is at the table or the one who serves? Is it not the one who is at the table? But I am among you as one who serves. 28 You are those who have stood by me in my trials. 29 And I confer on you a kingdom, just as my Father conferred one on me, 30 so that you may eat and drink at my table in my kingdom and sit on thrones, judging the twelve tribes of Israel.
31 âSimon, Simon, Satan has asked to sift all of you as wheat. 32 But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers.â
In other words, the question arises who the greatest of the Disciples is. Jesus says that the greatest is the one who will serve the others, and then tells Peter that once he has turned back (from betraying Christ) his job is strengthen the other Eleven. He tells this
only to Peter.
In fact, itâs even more incredible in Greek, because Jesus says âSatan desires to sift you (plural) like wheat, but I have prayed for you (singular), Simon.â All of the Disciples, not just Peter, chickened out. And Satan was after them all. But Jesus chose Peter for a special role, and prayed for him particularly, and then entrusted him to take care of the other Disciples.
II. Jesus tells Peter that it is upon him that He (Jesus) will build the Church.
This is in Matthew 16:17-19. He changes Simonâs name to Peter, which means âRock,â and He says to him, âBlessed are you, Simon bar-Jona, âŚ] And I tell you, you are Rock, and upon this rock I will build my Church.â He then promises Peter the Keys to the Kingdom of Heaven, and the power to bind and loosen sins, and promises that the gates of Hell will not prevail against the Church built upon Peter.
In changing Simonâs name to Peter, we see something very similar to what He did in changing Abramâs name to Abraham in Genesis 17:3-8. It was a change in Abrahamâs status, as he became the earthly head of Godâs covenantial people. The same thing happens with Simon Peter in the New Covenant. In giving Peter the Keys, Jesus recalls the palace administrator, who served as a mouthpiece of the king (see Isaiah 22:20-24 for a very similar âKeysâ discussion). The difference is that instead of having the Keys to the House of David, as Eliakim did (enabling him to speak on behalf of the king, as requested â 2 Kings 18 has a good example of this).
Christ depicts Himself also as the eternal holder of the Keys, in Heaven (Revelation 1:18). So Jesus has bestowed upon Peter some earthly echo of the infinite Heavenly authority Jesus Christ Himself possesses in Heaven.
III. Similar to the last point, Jesus depicts Himself as âthe Good Shepherdâ In John 10:11-19. He is, in other words, the perfect Godly model for all pastors (âPastorâ just being Latin for âShepherd,â after all). Peter calls Jesus âthe Chief Shepherdâ in 1 Peter 5:4. But God also promised to provide us with âShepherds after [His] own Heartâ in Jeremiah 3:15. And
right before the Good Shepherd parable, Jesus gave another very similar parable, the Parable of the Sheep-Gate. Read John 10:1-10. There, Jesus describes Himself as the Gate through which another shepherd will pass. He says in John 10:9, " I AM the Gate;" and in John 10:2, âThe one who enters by the Gate is the shepherd of the sheep.â So Heâs talking
about someone besides Himself who will enter âby the Gateâ (that is, be called personally by Christ) to become the shepherd of the sheep. From Jesusâ explanation of the Good Shepherd parable, which immediately follows, we know that the âsheepâ include all Christians everywhere, both Jewish and Gentile (John 10:16).
Flash forward to John 21:15-17. Jesus asks Peter three questions (in English, roughly, âDo you love Me more than these?â âDo you love Me?â and âDo you like Me?â), and after Peter answers, Jesus instructs him: âFeed My lambs,â âTend My sheep,â and âFeed My sheep.â In other words, the one entered by the Gate, who was called to be shepherd by the Good Shepherd Himself, was Peter. And note that in John 21:15, Jesus contrasts Peterâs love
with the love of the other Disciples, by asking, âDo you love Me
more than these?â
