13. And Jesus coming - There was a large interval of time between what has been related, and what follows. The passages that follow were but a short time before our Lord suffered. Mark viii, 27; Luke ix, 18.
14. Jeremiah, or one of the prophets - There was at that time a current tradition among the Jews, that either Jeremiah, or some other of the ancient prophets would rise again before the Messiah came.
16. Peter - Who was generally the most forward to speak.
17. Flesh and blood - That is, thy own reason, or any natural power whatsoever.
18. On this rock - Alluding to his name, which signifies a rock, namely, the faith which thou hast now professed; I will build my Church - But perhaps when our Lord uttered these words, he pointed to himself, in like manner as when he said, Destroy this temple, John ii, 19; meaning the temple of his body. And it is certain, that as he is spoken of in Scripture, as the only foundation of the Church, so this is that which the apostles and evangelists laid in their preaching. It is in respect of laying this, that the names of the twelve apostles (not of St. Peter only) were equally inscribed on the twelve foundations of the city of God, Rev. xxi, 14. The gates of hell - As gates and walls were the strength of cities, and as courts of judicature were held in their gates, this phrase properly signifies the power and policy of Satan and his instruments. Shall not prevail against it - Not against the Church universal, so as to destroy it. And they never did. There hath been a small remnant in all ages.
19. I will give thee the keys of the kingdom of heaven - Indeed not to him alone, (for they were equally given to all the apostles at the same time, John xx, 21, 22, 23;) but to him were first given the keys both of doctrine and discipline. He first, after our Lord's resurrection, exercised the apostleship, Acts i, 15. And he first by preaching opened the kingdom of heaven, both to the Jews, Acts ii, , and to the Gentiles, Acts x, . Under the term of binding and loosing are contained all those acts of discipline which Peter and his brethren performed as apostles: and undoubtedly what they thus performed on earth, God confirmed in heaven. Matt. xviii, 18.
