In the passage about dealing with unrepentant sinners, Jesus is discussing this with His Apostles. So when He says “the Church,” he means the leaders of the community.
Do only apostles belong to the church? Are you not a member of Christ’s body? Does the church not have a general, corporate existence? When Jesus says, “Tell it to the church” why wouldn’t he mean exactly what he said—tell it to the local assembly of Christians (of course only after laboring privately to bring the offending brother to repentance and then with a smaller group of Christians as witnesses)?
Nowhere in that passage does Jesus give the other Apostles the keys.
He gives Peter the keys in Matthew 16. A key conveys authority to open a door and give entrance. We can see this in Jesus’ use of the phrase “key of knowledge” in Luke 11:52, where he accuses the teachers of the law from taking away this key from the people, “you did not enter yourselves, and you hindered those who were entering.” We also see this meaning in Jesus’ use of the phrase “keys of Death and Hades” in Revelation 1:18. Jesus is saying he has the power to allow entrance and exit from these places or states of existence.
So, we can say that at the least Peter was given authority to open the door of the kingdom of heaven and allow people to enter. How would he do this? By preaching the gospel of Christ. We see this first at Pentecost, when Peter speaks for the other 11 in explaining to onlookers what is going on. When they ask the apostles, “Brothers, what shall we do,” Peter opens the door to the kingdom of heaven saying, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”
Yet, Peter was not alone in opening the door to the kingdom of heaven. The other apostles also preached and were given authority along with Peter to preserve the gospel in written form. In fact, all Christians today can share the gospel with others, thereby opening up the kingdom of heaven to those who will enter.
So yes, Peter and the other apostles and all Christians today possess the keys to the kingdom, and that should give us pause and make us reflect on how we are using such a gift or if we are allowing opportunities to witness to others to pass us by and thereby leave this door closed for others.
Now, the church is not just given a key. It is given keys, which suggest different kinds of authority besides preaching the gospel. It is clear from the inclusion of the words “bind” and “loose” in Matthew 16:19 (which is identical to the language used in Matthew 18) that this also includes authority to impose church discipline and to release from such discipline. Therefore, we can say that the keys to the kingdom of heaven refer to admitting people to the kingdom through preaching the gospel (which any Christian can do) and authority to exercise church discipline for those who do enter (which is an authority given to the church as a body whenever it meets and carries out such discipline).
In Luke 22 Jesus specifically tells Peter he’s gonna strengthen his brothers. If that’s not authority, then what is?
I can strengthen my brothers and sisters without ordering them to do what I want; I can strengthen my friends without being in a hierarchical relationship with them through encouragement and my example.
The Greek word used in John 21 means govern. So Jesus is saying to Peter, “Govern my sheep.” Jesus is putting Peter in charge of his brothers.
Yes, Peter is being called to shepherd the sheep, but this does not mean he has sole responsibility to do this nor that he has the chief responsibility for this. The text does not point to any superior position for Peter In relation to the other apostles. Others are called to shepherd the flock of God in the New Testament, and therefore, merely saying “tend my sheep” is not enough to imply supreme leadership as others were also called to “govern” the flock of God .
The author of 1 Peter 5:1 exhorts the elders of the churches he addresses to “shepherd the flock of God that is among you, exercising oversight, not under compulsion, but willingly, as God would have you; not for shameful gain, but eagerly; not domineering over those in your charge, but being examples to the flock.” In Ephesians 4:11, Paul teaches that Christ gave the church shepherds in addition to other types of leaders.
:Where are these others in the dialogue? I just see Christ speaking to Simon Peter…
He’s speaking to Peter, but Christ’s doing it for the benefit of clearing up Peter’s own status since “the thrice-repeated denial was special and peculiar to him”. As Church Father Cyril of Alexandria writes in Book 12 of his
Commentary on John:
And what is the meaning of the words, Feed my Lambs, and the like? We reply, that the inspired Peter had indeed already been elected, together with the other disciples, to be an Apostle of God, but, when the events connected with the plot of the Jews against Him came to pass, his fall came betwixt; for the inspired Peter was seized with uncontrollable fear, and he thrice denied the Lord . . . Therefore, by his thrice-repeated confession the thrice-repeated denial of the blessed Peter was done away with, and by the saying of our Lord, “Feed my lambs,” we must understand a renewal as it were of the apostleship, already given unto him, washing away the disgrace of his fall that came betwixt, and obliterating his faint-heartedness, that arose from human infirmity.
