Daddy… It is Good that you pointed out the rock which represents Christ in the scriptures but what you haven’t done is point out that rock is used many times in reference to other things/persons in scripture. The scripture is full of words that can be used to represent things. This rock or that rock. The rock which the Church was built on is Peter. The Rock being the metaphor for something solid that is built upon like a Rock.
Here’s some examples where the rock was used to represent someone other than Christ.
Deuteronomy 32:30 How should one chase a thousand, and two put ten thousand to flight, unless their Rock had sold them, and the Lord had given them up?.
Deuteronomy 32:37 Then he will say, ‘Where are their gods, the rock in which they took refuge,
Isaiah 31:9 His rock shall pass away in terror, and his officers desert the standard in panic,” says the Lord, whose fire is in Zion, and whose furnace is in Jerusalem.
You are right with these. Rock is used to as a symbol of other gods.
1 Samuel 23:28 So Saul returned from pursuing after David, and went against the Philistines; therefore that place was called the Rock of Escape.
Here it is used as the name of a place
Deuteronomy 32:31 For their rock is not as our Rock, even our enemies themselves being judges.
1 Samuel 2:2 “There is none holy like the Lord, there is none besides thee; there is no rock like our God
These two however are used to represent the God of Israel. And that Rock is Jesus.
Now if the rock represents Christ in Matthew 16:18 it would not make any sense grammatically.
Matthew 16:18 And I tell you that you are Peter, and on this rock (JESUS) I will build my (JESUS) church, and the gates of Hades will not overcome it.
Jesus rather would say something like. This is my church and I want it built on me. It just doesn’t make sense that Jesus would make such a statement known to Peter. Jesus made the statement to Peter because He wanted Peter to lead the Church (on earth).
Well, maybe if you take verse 18 out of context, but if you keep it in context with the rest of the exchange with Jesus, it makes perfect sense.
Matt16
13 When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?
14 And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.
15 He saith unto them, But whom say ye that I am?
16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
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.
First of all Jesus is inquiring of His disciples 1.who do people and 2. who do you say that I (not Peter) am. Then Peter, who usually sticks his foot in his mouth says exactly the right thing, that Jesus is the messiah, but He doesn’t allow him to get a big head. He points out that this observation doesn’t come from Peter, but from the Father. Then we get to the controversial verse 18. And here Matt under the guidance of the Holy Spirit choses two words for rock. Petros for Peter and Petrah for the rock upon which Christ builds His church, Himself. I believe this was done purposely so that the distinction would be apparent. I believe this was a masterful technique and left no doubt who Jesus was talking about. Especially since in verse 18 Jesus says that the gates of hell will not prevail against it and in vs.21-23 Satan does prevail against Peter.
21 From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.
22 Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.
23 But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
Jesus confirms this by telling Peter to Feed His Sheep.
Jesus is telling this to all of us.
