Caesarea Philippi: The site of Peter’s confession of Christ.
Jesus took his disciples to Caesarea Philippi, the site of the temple of the Greek god Pan, one of the greatest pagan temples of the ancient world. At the temple Pan there is a cave that was referred to as the gates of Hell or Hades, the doorway to the underworld.
“The Gates of Hell will not prevail against it” refers to the guaranteed ultimate victory of Christ’s Kingdom over all the pagan religions.
Matthew 16:13-19 NIV
13When Jesus came to the region of Caesarea Philippi, he asked his disciples, “Who do people say the Son of Man is?”
14They replied, “Some say John the Baptist; others say Elijah; and still others, Jeremiah or one of the prophets.”
15″But what about you?” he asked. “Who do you say I am?”
16Simon Peter answered, “You are the Christ, the Son of the living God.”
17Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven. 18And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. 19I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
