The keys of the kingdom of heaven Matthew 16:13-20
When Jesus came to the region of Caesarea Philippi he put this question to his disciples, “Who do people say the Son of Man is?” They said, “Some say he is John the Baptist, some Elijah and others, Jeremiah or one of the prophets.” But you,” he said, “who do you say I am?” Then Simon Peter spoke up, “You are the Christ,” he said “the Son of the living God.” Jesus replied, “Blessed are you Simon, son of Jonah, for flesh and blood has not revealed this to you but my Father in heaven. So I now say to you: You are Peter and on this rock I will build my Church and the gates of the underworld can never hold out against it.
I will give you the keys of the kingdom of heaven: whatever you bind on earth shall be considered bound in heaven; whatever you loose on earth shall be considered loosed in heaven.” Then he instructed his disciples not to tell anyone that he was the Messiah.”
