Matthew 16:19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
In the above passage, Peter was not given a special set of keys to the kingdom that was not available to the other disciples. The keys to the kingdom are in fact given to every believer, for they consist of every word in the Bible, which contains the revealed will of God. A key is a mechanism by which on can gain entrance to a place, person, or thing, and therefore, we must never conclude that just because Jesus singled out Peter by name on this occasion that the others were left out.
They were not. John is specifically described in the Scriptures as the disciple that Jesus loved. This does not mean that Jesus did not love the other disciples. Thus, because Christ names one person specifically in an instance, we are not to conclude that some special privilege is granted to pardon, that the others are not privy to.
Thus, if we were to reason along strictly logical lines we would have to conclude that by handing the keys of the kingdom to Peter, Jesus thereby gave satan the keys, because of how He addressed Peter, later on in verse 23…. [The Desire of Ages pp 413>414] “The keys of the kingdom of heaven” are the words of Christ. All the words of Holy Scripture are His, and are here included.
John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
May God add His blessing to the study of His word. “Good night” and God bless!
