This Jesus After that he had proved by the testimony of David, that it was most requisite that Christ should rise again, he saith, that he and the rest of his fellows were such witnesses as saw him with their eyes after his resurrection. For this text [1] will not suffer this word raised up to be drawn into any other sense. Whereupon it followeth that that was fulfilled in Jesus of Nazareth which David did foreshow concerning Christ. After that he intreateth of the fruit or effect. For it was requisite for him to declare that first, that Christ is alive. Otherwise it had been an absurd and incredible thing that he should be the author of so great a miracle. Notwithstanding he doth therewithal teach us, that he did not rise for his own sake alone, but that he might make the whole Church partaker of his life, having poured out the Spirit.
1 - "Contextus," context.
This Jesus - Peter, having shown that it was predicted that the Messiah would rise, now affirms that such a resurrection occurred in the case of Jesus. If it was a matter of prophecy, all objection to the truth of the doctrine was taken away, and the only question was whether there was evidence that this had been done. The proof of this Peter now alleges, and offers his own testimony, and that of his brethren, to the truth of this great and glorious fact.
We are all witnesses - It seems probable that Peter refers here to the whole 120 who were present, and who were ready to attest it in any manner. The matter which was to be proved was that Jesus was seen alive after he had been put to death. The apostles were appointed to bear witness of this. We are told by Paul 1-Corinthians 15:6 that he was seen by more than five hundred brethren, that is, Christians, at one time. The 120 assembled on this occasion were doubtless part of the number, and were ready to attest this. This was the proof that Peter alleged; and the strength of this proof was, and should have been, perfectly irresistible:
(1) They had seen him themselves. They did not conjecture it or reason about it; but they had the evidence on which people act every day, and which must be regarded as satisfactory the evidence of their own senses.
(2) the number was such they could not be imposed on. If 120 persons could not prove a plain matter of fact, nothing could be established by testimony; there could be no way of arriving at any facts.
(3) the thing to be established was a plain matter. It was not that they "saw him rise." That they never pretended: Impostors would have done this. But it was that they saw him, talked, walked, ate, drank with him, being alive, after, he had been crucified. The fact of his death was matter of Jewish record, and no one called it in question. The only fact for Christianity to make out was that he was seen alive afterward, and this was attested by many witnesses.
(4) they had no interest in deceiving the world in this thing. There was no prospect of pleasure, wealth, or honor in doing it.
(5) they offered themselves now as ready to endure any sufferings, or to die, in attestation of the truth of this event.
Whereof we all are witnesses - That is, the whole 120 saw him after he rose from the dead, and were all ready, in the face of persecution and death, to attest this great truth.
(7) This Jesus hath God raised up, whereof we all are witnesses.
(7) Peter witnesses that Jesus Christ is the appointed everlasting King, which he manifestly proves by the gifts of the Holy Spirit and the testimony of David.
This Jesus hath God raised up,.... That is, from the dead,
whereof we are all witnesses; namely, of his resurrection, they having seen him, and heard him, and ate, and drank, and conversed with him since his resurrection; and which was true, not of the twelve apostles only, but of the whole company: or "we are all his witnesses"; either of God, who raised Christ from the dead; or of Christ who was raised by him; and indeed, they bore testimony to the whole of this, to Christ, and to his resurrection, and to its being done by God the Father.
This Jesus hath God raised up. David foretold it; we are all witnesses of it. There were, including himself, at least twelve witnesses there who had seen the risen Lord again and again. The next point is the exaltation of Christ to a heavenly throne.
He foreseeing this, spake of the resurrection Of Christ - St. Peter argues thus: It is plain, David did not speak this of himself. Therefore he spake of Christ's rising. But how does that promise of a kingdom imply his resurrection? Because he did not receive it before he died, and because his kingdom was to endure for ever, 2-Samuel 7:13.
