Matthew 16; Mark 8; Luke 9

The Pharisees demand a sign from Jesus, not believing Him, even yet. Watch out for their teaching, or anyone's today, if they don't know the Source of Truth. But the disciples believe Jesus is the Son of the living God, and Jesus will build His church on them and their belief. They will have His authority (the keys), but will also need to imitate Him in taking up the cross.
