Thank you sourberry for your topic.
By contrast here are some other words Jesus said to Peter.
Subject: Peter's Confession.
Mat 16:15 He said to them, "But who do you say that I am?"
Mat 16:16 Simon Peter answered and said, "You are the Christ, the Son of the living God."
Mat 16:17 Jesus answered and said to him, "Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven.
Mat 16:18 "And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it.
There is a play on words here in verse 18, which could be rendered as, "you are Petros, and on this Petra I will build My church".
Everything in the Bible is there for a reason, although we may not at first understand why.. We are given the geographic location of this incident as "Caesarea Philippi", which as I am sure you know is situated at the base of Mount Hermon.
This is the highest mountain in Israel, and is right up in the north. It is snow capped for most of the year. This snow melts, and forms streams, which come out from the base of a vertical sandstone cliff face at Caesarea Philippi.
You can find Photographs of Caesarea Philippi on the Internet, these will show not only a cliff face about 100 feet tall, and about 250/300 feet wide, but also a flat bed stream with small stones/pebbles in the water.
The vertical soft rock was ideal for carving alcoves in, and into these alcoves were placed images of the many false gods worshiped at that time, including "pan".
It is therefore against this background of dead false god worship, that our Lord reveals the one and only true, and living God. It was also a suitable place to refer to "Petros" (the Greek word for Peter, which can also mean pebble, or small stone) in the stream bed, and of course "Petra" (the Greek word for Rock*), but how is He to do this as He speaks in Aramaic*? (Remember Matthew would be there not only to hear what Jesus said, but also to see what He did).
Could it be I wonder that when Jesus spoke, that He pointed to both the stream, and the cliff face?.. And now to "Bar-Jonah" . Firstly it suggests that Jesus was speaking in Aramaic, but more important why did He not just say Peter. or even Simon Peter?, why bar-Jonah?. Is He referring to the name of Peter's father, No because Peter's father was called John,see.
NIV - Jhn 1:42 - And he brought him to Jesus. Jesus looked at him and said, “You are Simon son of John. You will be called Cephas” (which, when translated, is Peter).
I believe that He is using the well known custom of describing a man's nature as being just like that of the person referred to, ie in this case the prophet Jonah. Now in what way is Peter like Jonah. God spoke to Jonah, telling him where to go, but Jonah went in the opposite direction. God spoke to Peter.. Act 10:14 But Peter said, "Not so, Lord! For I have never eaten anything common or unclean"..
So what was Jonah told to do?. Go to Nineveh, a gentile city, and where did he go to, he went to Joppa, where was Peter in acts Ch 10, Joppa.. He was told to eat, he refused.. Afterwards Jonah went to Nineveh a city of three days journey, yet when he had only gone one day they all repented.. What did Peter do, he went to a gentile household, and before he had finished his sermon, they all repented. Now do you see.
* Petra the Greek word for Rock, can mean a whole cliff face or even mountain side, see Petra, a location in southern Jordan.
* Aramaic, I have been told that there is only one word in Aramaic for pebble, stone, rock.
Petra. What did Jesus mean when He said, "and on this rock (perta) I will build My church,"
There is no doubt in my mind, that our Lord Jesus Christ is indeed the foundation on which His Church is built, i.e. 1 st Cor Ch 3 v 11, however, I do not think that He was referring to Himself when speaking as recorded at Matthew Ch 16 v 18, but to what had just happened to Peter.
I believe He was saying that His Church would consist of individuals, each of whom will have exactly what Peter had just had, i.e. direct Divine intervention into their lives, enabling them to accept Jesus as Savior. John Ch 6 vs 44 & 65.
God bless you.
