Yes—Peter's resurrection preaching was significant because it confronted the Sadducees' denial of the resurrection and declared the crucified Jesus as the living source of salvation.
Peter and John were teaching the people and 'preached through Jesus the resurrection from the dead' (Acts 4:2), which directly challenged the Sadducees, who believed in no resurrection. Peter then made plain that the healing at the temple gate was done by the name of Jesus Christ of Nazareth—whom the leaders crucified and whom God raised from the dead (Acts 4:10). Les Feldick stresses that Peter's own fearlessness after the resurrection is one of the greatest proofs of that resurrection.
Acts 4:2 — This verse names the exact issue: the priests and Sadducees were grieved that the apostles taught the people and preached through Jesus the resurrection from the dead.
Acts 4:10 — Peter's answer shows the meaning of that preaching: the crucified Jesus was raised by God and is the source of the miracle.
The Bible records that while Peter and John were speaking to the people, "the priests, and the captain of the temple, and the Sadducees, came upon them, being grieved that they taught the people, and preached through Jesus the resurrection from the dead" (Acts 4:1–2). The Sadducees did not believe in the resurrection, so the message was a direct contradiction of their doctrine. When Peter was asked by what power or name the lame man had been healed, he answered, "Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole" (Acts 4:10). He added, "Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved" (Acts 4:12). Scripture also records Peter's earlier words to Israel: "And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses" (Acts 3:15). And on the day of Pentecost Peter concluded, "God hath made that same Jesus, whom ye have crucified, both Lord and Christ" (Acts 2:36).
Les Feldick says the Sadducees are the one group most concerned about Peter's preaching because they believed in no resurrection from the dead and no afterlife—"you lived like an animal and you died like an animal." So when Peter preached that Christ is alive and can still come to be their King, he was flying in the face of their doctrine. Peter's message that "whom God raised from the dead" was spoken especially for the benefit of the Sadducees. At the same time, Les emphasizes what the resurrection did to Peter himself. Peter had collapsed at Christ's arrest, cursed and denied that he ever knew Him, and he and the others ran in fear. But after the resurrection, Peter was afraid of nobody—not Rome, not the Jews—because he had witnessed the power of the resurrection. Les calls the resurrection the bedrock of the Gospel; it is not enough to believe Jesus was a good man or that He died a crucifixion. Les also places the preaching in its Acts setting. God, having raised up His Son Jesus, sent Him to bless Israel, and every Jew had to repent and be baptized in order for the King to usher in the tribulation, lift the curse, and bring in the kingdom. This was a valid offer over the forty-year period from the crucifixion to the temple's destruction, though God knew Israel would refuse it. In Acts 3, Les observes, Peter does not even allude to the death, burial, and resurrection formula; instead he reminds Israel of who Jesus really was—the Prince of Life—and calls them to faith in that name.
Les Feldick explains that the Sadducees, unlike other groups in Israel, had no belief in a resurrection from the dead. Their doctrine was that "you lived like an animal and you died like an animal." So when Peter preached through Jesus the resurrection from the dead—and specifically that Christ is alive and is yet able to come as Israel's King—the Sadducees saw it as a direct attack on their teaching.
Peter told the gathered leaders that the lame man stood whole by the name of Jesus Christ of Nazareth, "whom ye crucified, whom God raised from the dead" (Acts 4:10). He said this especially for the benefit of the Sadducees. Peter also applied Psalm 118 to Jesus, calling Him "the stone which was set at nought of you builders" and declaring that no other name under heaven offers salvation (Acts 4:11–12). In Acts 3, Peter reminded Israel that they had killed the Prince of life and that God had raised Him from the dead (Acts 3:15). Les notes that in Acts 3 Peter doesn't even allude to the death, burial, and resurrection formula; instead he reminds the Israelites who Jesus really was and calls them to faith in that name.
Les points out that Peter was not always this bold. At Christ's arrest, his whole facade melted away, and he cursed and denied that he ever knew Jesus. But after the resurrection, Peter feared no one—not Rome, not the Jews—because he had witnessed the power of the resurrection. Les says Peter himself is one of the strongest proofs that Jesus rose from the dead. He also reminds readers that all the eleven apostles, as near as he can tell, were martyred without fear for the same reason.
Les places Peter's resurrection preaching within God's continued dealings with Israel in Acts. From the crucifixion to the destruction of the temple was a forty-year period of testing. Peter told the Jewish crowds, "You killed your Messiah," and called every Jew to repent and be baptized. If Israel as a nation had responded, Christ would have brought in the kingdom and lifted the curse; but God knew Israel would not repent, so He would go to the Gentiles without Israel.
Israel's Forty-Year Window
Les explains that Peter's call to repentance and the offer of the kingdom was part of God's continued dealings with Israel during the forty years between the crucifixion and the temple's destruction.
Sadducees Denied the Resurrection
Les points out that the Sadducees believed no one rises from the dead, making them the group most threatened by Peter's preaching that Jesus is alive and able to come as King.
Peter's Declaration to the Sadducees
Les highlights Peter's direct words: the healing was by the name of Jesus Christ of Nazareth, whom the leaders crucified and God raised from the dead—there is no other name for salvation.
Resurrection Makes Peter Fearless
Les contrasts Peter's terrified denial at Christ's arrest with his post-resurrection boldness; having witnessed the resurrection, Peter feared no one, and Les calls the resurrection the bedrock of the Gospel.
'You Killed Your Messiah'
Les shows Peter declaring to the Jewish crowd, "whom you crucified," prompting their response, "what must we do?"—the resurrection was preached to the very people who had killed Jesus.
Peter as Proof of the Resurrection
Les identifies Peter himself as the outstanding proof of the resurrection: the man who swore he did not know Jesus became bold beyond shaking after seeing the risen Lord.
Apostles' Fearless Martyrdom
Les says the resurrection changed the eleven disciples so completely that Peter stood up to Rome and all of them, as far as he can tell, were martyred without fear.
Peter's Focus on Who Jesus Is
Les notes that in Acts 3 Peter does not lay out the death, burial, resurrection formula; instead he reminds Israel that they killed the Prince of Life, whom God raised, and calls them to faith in that name.
Acts 4:2: Being grieved that they taught the people, and preached through Jesus the resurrection from the dead.
Records that the Sadducees specifically were grieved at Peter's preaching of the resurrection through Jesus.
Acts 4:10: Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.
Peter's public declaration that the healed man stood whole by the name of the crucified and risen Jesus.
Acts 4:11: This is the stone which was set at nought of you builders, which is become the head of the corner.
Peter applies Psalm 118 to Jesus, showing the rejected and risen Christ is now the cornerstone.
Acts 4:12: Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
The death and resurrection are tied to the exclusive salvation found in Jesus' name.
Acts 3:15: And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.
Peter charges Israel with killing the Prince of life and testifies that God raised Him from the dead.
Acts 2:36: Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
Peter's Pentecost conclusion that the crucified Jesus is made both Lord and Christ.
Acts 2:38: Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
The required response for Israel in Acts: repent and be baptized in Jesus' name.
Les Feldick explains that the Sadducees did not believe in any resurrection—"you lived like an animal and you died like an animal." Peter's preaching that Christ is alive and can come as King directly contradicted that doctrine, so they confronted him.
Peter declared that the lame man was healed by the name of Jesus Christ of Nazareth, whom the leaders crucified and whom God raised from the dead. He added that the stone the builders rejected had become the head of the corner, and that no other name under heaven offers salvation.
Before the crucifixion Peter denied Jesus with curses and ran in fear. After the resurrection he was afraid of no one. Les Feldick points to Peter himself as one of the clearest proofs of the resurrection—his new boldness could not be shaken.
