“And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.”
Matthew 16:19 — Greek Interlinear
Church Fathers on Matthew 16:19
As soon as the Lord had taken His disciples out of the teaching of the Pharisees, He then suitably proceeds to lay deep the foundations of the Gospel doctrine; and to give this the greater solemnity, it is introduced by the name of the place, 'When Jesus came into the coasts of Caesarea Philippi.'
He adds 'of Philip,' to distinguish it from the other Caesarea, of Strato. And He asks this question in the former place, leading His disciples far out of the way of the Jews, that being set free from all fear, they might say freely what was in their mind.
This Philip was the brother of Herod, the tetrarch of Ituraea, and the region of Trachonitis, who gave to the city, which is now called Panaeas, the name of Caesarea in honour of Tiberias Caesar.
