Douay-Rheims Bible: Matthew — Introduction, Chapter Summaries and Notes by Richard Challoner
Chapter 16
SummaryChrist refuses to shew the Pharisees a sign from heaven. Peter's confession is rewarded. He is rebuked for opposing Christ's passion. All his followers must deny themselves.
[16:18] Thou art Peter, etc. . .As St. Peter, by divine revelation, here made a solemn profession of his faith of the divinity of Christ; so in recompense of this faith and profession, our Lord here declares to him the dignity to which he is pleased to raise him: viz., that he to whom he had already given the name of Peter, signifying a rock, St. John I. 42, should be a rock indeed, of invincible strength, for the support of the building of the church; in which building he should be, next to Christ himself, the chief foundation stone, in quality of chief pastor, ruler, and governor; and should have accordingly all fulness of ecclesiastical power, signified by the keys of the kingdom of heaven. Upon this rock, etc. . . The words of Christ to Peter, spoken in the vulgar language of the Jews which our Lord made use of, were the same as if he had said in English, Thou art a Rock, and upon this rock I will build my church. So that, by the plain course of the words, Peter is here declared to be the rock, upon which the church was to be built: Christ himself being both the principal foundation and founder of the same. Where also note, that Christ, by building his house, that is, his church, upon a rock, has thereby secured it against all storms and floods, like the wise builder, St. Matt. 7. 24, 25. The gates of hell, etc. . . That is, the powers of darkness, and whatever Satan can do, either by himself, or his agents. Tor as the church is here likened to a house, or fortress, built on a rock; so the adverse powers are likened to a contrary house or fortress, the gates of which, that is, the whole strength, and all the efforts it can make, will never be able to prevail over the city or church of Christ. By this promise we are fully assured, that neither idolatry, heresy, nor any pernicious error whatsoever shall at any time prevail over the church of Christ.
[16:19] Loose on earth. . . The loosing the bands of temporal punishments due to sins, is called an indulgence; the power of which is here granted.
[16:22] And Peter taking him. . . That is, taking him aside, out of a tender love, respect and zeal for his Lord and Master's honour, began to expostulate with him, as it were to rebuke him, saying. Lord, far be it from thee to suffer death; but the Lord said to Peter, ver. 23, Go behind me, Satan. These words may signify, Begone from me; but the holy Fathers expound them otherwise, that is, come after me, or follow me; and by these words the Lord would have Peter to follow him in his suffering, and not to oppose the divine will by contradiction; for the word sat an means in Hebrew an adversary, or one that opposes.
