Matthew 16:15

Then they understood that he didn’t tell them to beware of the yeast of bread, but of the teaching of the Pharisees and Sadducees.

Now when Jesus came into the parts of Caesarea Philippi, he asked his disciples, saying, “Who do men say that I, the Son of Man, am?”

They said, “Some say John the Baptizer, some, Elijah, and others, Jeremiah or one of the prophets.”

Simon Peter answered, “You are the Christ, the Son of the living God.”

Jesus answered him, “Blessed are you, Simon Bar Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven.

I also tell you that you are Peter, and on this rock I will build my assembly, and the gates of Hades will not prevail against it.
