2 Peter

Simon Peter spoke Aramaic and he was not educated in the law.  He was a fisherman and he shows up first in John 1.  His brother Andrew hears Jesus speak and runs to tell Simon that he had found the Messiah.  Andrew brought him Jesus.  Jesus said to Peter that he will be called Cephas or Peter which means stone.  In Matthew 16:13 we see that Jesus is at Caesarea Philippi where Peter answers Jesus’ question that he was the Christ and Son of the living God.  Jesus proclaimed him to be Peter.  Jesus said he would build his church on the rock.   Jesus would build His church on the confession that Christ was the Son of the Living God.  Some have confused the proclamation of Christ to be a determination of building His church on Peter.  See 1 Corinthians 12:4 that Jesus is the rock.   

Just like Israel and Jacob, Peter had 2 names.  The name of Simon was used in worldly and sinful nature contexts.  Where Peter is his spiritual name and used to reveal him as a saint.  Through this we can each see we each have these 2 natures and can relate to Peter.
