Blessed are you, Simon son of Jonah, because no human has revealed this to you, but my Father in heaven.
18 You are Peter, and upon this rock I will build my church. And the gates of hell will not prevail against it.
19 I give you the keys to the kingdom of heaven. Whatever you forbid on earth shall forbidden in heaven, and whatsoever you allow on earth will be allowed in heaven.
20 Then Jesus told his disciples not to tell anyone that he was the Christ.
Jesus foretells his death and resurrection (and calls Peter "Satan")
21 From this time on, Jesus began to explain to his disciples how he must go to Jerusalem; suffer many things from the elders, priests, and scribes; be killed; and raised again on the third day.
22 Then Peter took him aside and said, "Lord, this will not happen to you!"
Because of your unbelief. If your faith is as small as a mustard seed, you can say to a mountain, "Move over there" and it will move. Nothing will be impossible for you.
21 But this one can only be removed by prayer and fasting.
Jesus foretells his death (again)
22-23 While Jesus and his disciples were in Galilee, Jesus said to them,
The Son of man will be betrayed into the hands of men, who will kill him, and on the third day he will be raised from the dead.
Jesus pays his taxes (by taking a coin out of a fish's mouth)
24 When they came to Capernaum, they who receive tribute money came to Peter, and said, "Does your master pay the tribute?"
But to avoid offending them, go to the sea, cast in a hook, and catch the first fish that comes up. When you have opened his mouth, you'll find a coin. Take that and give it to them for you and me.
A few more words about this episode
The sign of Jonah (16:1-4)
Jesus calls the scribes and Pharisees a wicked and evil generation (because they asked him for a sign). He says he'll only give them the sign of Jonah.
I left this out of the podcast since Jesus already said it in Mt 12:38-42. (Episode 239)
When you have opened his mouth, you'll find a coin. (17:27)
Although the species of fish isn't named, it is often said to have been a tilapia, which are found in the Sea of Galilee and are sometimes called "St. Peter's fish".
