When Christ named Peter(the Rock)from Simon. He is addressing someone outside of himself because Christ is the builder.
Matthew 18 And I tell you, you are Peter(The Rock),[d] and on this rock[e] I will BUILD MY church, and the powers of death[f] shall not prevail against it.[g] 19 I will give you the keys of the kingdom of heaven,[h] and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
“And I Tell YOU, YOU ARE PETER” He changed the name Simon to PETER. Which means ROCK.
When God Changes names something is happening here. Peter is the Rock. He is addressing PETER without a doubt.
When I say in a conversation “ And I TELL YOU” I am pointing out to you . He is obviously addressing To the one he is talking at in the conversation.
Then if I would put “YOU ARE PETER” I am emphazing you are the ROCK also to the next words- “ and on this ROCK I will BUILD MY church, and the powers of death[f] shall not prevail against it.[g]
19 I will give YOU the KEYS of the kingdom of heaven,[h] and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
He is addressing “The Rock”that was named by him. PETER.
Also when you give Keys those Keys are to be passed on to someone responsible as a leader. I have a house with keys. I only pass them on to who is to be trusted.
Peace in Christ to All
It should also be noted that every time Jesus said “you” to Peter in the Original Greek it was in the Singular not the plural.
Peter understood the NAME in Matthew 28:19, and ALWAYS baptized in the name of JESUS. The power is in the NAME.
Call him the ‘rock’, but your church doesn’t obey him.
Oh, and Andrew knew Jesus was the Christ before Peter did.
Peter used the ‘keys’ alright; he had to be present for the Holy Ghost to be poured out to the three main groups of people: He opened the door to the Jews in Acts 2, to the Samaritans in Acts 8, and the Gentles in Acts 10.
