St. Peter was raised a fisherman in the house of Bar-Jonah and Brother of St. Andrew. Born in Bethsaida, near Lake Tiberias he was well acquainted with the Sea. Jesus called him Cephas (John 1:42) calling him to be a fisher of men (Matthew 4:19).
“Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, “Who do men say that the Son of man is?” And they said, “Some say John the Baptist, others say Elijah, and others Jeremiah or one of the prophets.” He said to them, “But who do you say that I am?” Simon Peter replied, “You are the Christ, the Son of the living God.” And Jesus answered him, “Blessed are you, Simon Bar-Jona! For flesh and blood has not revealed this to you, but my Father who is in heaven. And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” (Matthew 16:13-20)
Words to gleam from this scriptural text: Christ (Messiah), Rock (Kepa), Church (Εκκλησ?α/ekklesía), keys, bound (bind), and loose. From this text we see who Jesus is, Jesus is truly the Messiah, the Christ. We see Jesus identifying who Simon, Son of Bar-Jona is, the Rock (Kapa) and we see Jesus as the Son of David transferring the keys of authority from the household of David (Isaiah 22:22) now to Simon Peter and the household of God (1 Timothy 3:15).
