Matthew 16:6-19

Jesus said to them, “Watch out and be on your guard against the leaven of the Pharisees and Sadducees.” They began to discuss this among themselves, saying, “He said that because we did not bring bread.” But Jesus, aware of this, said, “You men of little faith, why are you discussing among yourselves that you have no bread? Do you still not understand or remember the five loaves for the five thousand, and how many baskets you picked up? Or the seven loaves for the four thousand, and how many large baskets you picked up? How is it that you fail to understand that I was not talking to you about bread? But beware of the leaven of the Pharisees and Sadducees.” Then they understood that He did not tell them to beware of the leaven of bread, but of the [false] teaching of the Pharisees and Sadducees. Now when Jesus went into the region of Caesarea Philippi, He asked His disciples, “Who do people say that the Son of Man is?” [Mark 8:27-29; Luke 9:18-20] And they answered, “Some say John the Baptist; others, Elijah; and still others, Jeremiah, or [just] one of the prophets.” He said to them, “But who do you say that I am?” Simon Peter replied, “You are the Christ (the Messiah, the Anointed), the Son of the living God.” Then Jesus answered him, “Blessed [happy, spiritually secure, favored by God] are you, Simon son of Jonah, because flesh and blood (mortal man) did not reveal this to you, but My Father who is in heaven. And I say to you that you are Peter, and on this rock I will build My church; and the gates of Hades (death) will not overpower it [by preventing the resurrection of the Christ]. [Eph 1:22; 4:15; 5:23; Col 1:18] I will give you the keys (authority) of the kingdom of heaven; and whatever you bind [forbid, declare to be improper and unlawful] on earth will have [already] been bound in heaven, and whatever you loose [permit, declare lawful] on earth will have [already] been loosed in heaven.” [Is 22:22; Matt 18:18]
