Peter and several of his companions travel to Caesarea to Cornelius’ home. Clinton Arnold, in notes that “six fellow Jewish believers from Joppa accompany Peter (see 11:12). This is significant because they will witness the Gentiles receiving the Holy Spirit and will be able to corroborate Peter’s story to Jewish believers in Jerusalem.”
They arrive the next day. Cornelius has invited close friends and relatives to hear what God’s messenger has to say. When Peter comes, Cornelius falls at his feet, as if he is worshiping Peter. Peter quickly corrects Cornelius and tells him that he is not to be worshiped because he is human, just as Cornelius.
Peter enters the house and reminds those inside that Jews are not allowed to enter the house of a Gentile, but that God showed him that this prohibition is no longer in effect. Clinton Arnold explains that
Jews typically did not enter a Gentile home (even that of a God-fearer) because they did not practice the same level of caution as observant Jews did to ensure that only kosher foods were eaten and that they were prepared in the proper way. There was also always the risk that the home may have had a household idol or other trappings of pagan idolatry. The best way for a Jew to be protected was never to enter a Gentile home.
So why did Peter believe the prohibition to no longer be in effect? John Polhill, in vol. 26, Acts, The New American Commentary, explains how Peter has come to this conclusion based on his previous vision.
Actually, Peter’s vision had only related to unclean foods, but he had understood fully the symbolism of the creatures in the sheet. All were God’s creatures; all were declared clean. God had led him to Cornelius, and God had declared Cornelius clean. The old purity laws could no longer separate Jew from Gentile. Since God had shown himself no respecter of persons, neither could Peter be one anymore. Still, Peter had not realized the full implication of God’s sending him to Cornelius. He did not yet understand that God intended him to accept Cornelius as a Christian brother.
He then asks Cornelius why he has sent for him. Cornelius recounts the story of the angel visiting him (this is the third time Luke has told the story), and then he asks Peter to share with them what God has commanded.
In verses 34-43 we have a summary of Peter’s message to this house full of Roman Gentiles. First, Peter tells them that God shows no partiality based on nationality or ethnicity. God will accept anyone who fears Him and does what is right. Arnold writes:
This is not a new idea in Judaism; it has always been in the Torah: ‘For the Lord your God is God of gods and Lord of lords, the great God, mighty and awesome, who shows no partiality and accepts no bribes’ (Deut. 10:17; see also 2 Chron. 19:7). This was a truth that many Jews had lost sight of, including Peter.
But is this “acceptance” equivalent to being saved from the final judgment? No. A person must take a further step to be saved. Peter continues: God sent the man Jesus Christ to bring peace to the nation of Israel. Peter assumes that his Roman audience in Caesarea has heard about the life of Jesus, a remarkable testament to how word about Jesus had spread. He reminds them that John baptized Jesus and that God anointed him with the Holy Spirit. Jesus then went about healing many people from suffering caused by the devil. Peter was a witness to all of this.
Arnold notes that
Peter’s words here echo and fulfill Isaiah 61:1-2: ‘The Spirit of the Sovereign Lord is on me, because the Lord has anointed me to preach good news to the poor. He has sent me to bind up the brokenhearted, to proclaim freedom for the captives and release from darkness for the prisoners.’ Jesus read these words at the outset of his ministry when he spoke in the synagogue at Nazareth (Luke 4:17-21).
Jesus was then crucified (hung on a tree), but God raised him from the dead on the third day. After he was raised, he appeared to a select group of people who also ate and drank with him. Peter specifically mentions eating and drinking with Jesus to clarify that Jesus physically and bodily rose from the dead. This was no ghost or apparition. Jesus commanded his disciples to teach that Jesus has been appointed, by God, to be the end-time judge. Anyone who believes in Jesus will receive forgiveness for his sins and escape the final judgment.
While Peter is speaking, he is interrupted by the Holy Spirit pouring into the Gentiles in Cornelius’ house. The Jewish companions of Peter are amazed at what is happening. Arnold explains:
The Torah-observant Jews recognize the remarkable significance of this event. God is now accepting Gentiles on the same basis that he did the Jews—on the sole basis of believing in Jesus Christ for the forgiveness of sins. These Gentile believers will not be required to be circumcised, offer sacrifices, observe the Jewish festivals, or keep Jewish dietary laws as a means of entering or maintaining their position in the new people of God.
Seeing this, Peter commands his companions to baptize these Gentiles in the name of Jesus Christ. Darrell Bock, in Acts, Baker Exegetical Commentary on the New Testament, summarizes:
God directs an epoch-making event in which Gentiles are accepted in fellowship and receive the gospel. Their faith leads to the gift of the Spirit, the sign that the new era has arrived. In addition, they are not circumcised and yet table fellowship and full hospitality between Jews and Gentiles ensues.
The Trinity is quite active here (Gaventa 2003: 173–74). God takes the initiative. Jesus Christ is at the center of the plan. The Spirit confirms that all of this is God’s work. The actions that take place represent the act and will of God working in harmony. The church does not lead here but follows God’s leading, thereby learning a great deal about how God views people.
Jews and Gentiles are equal in Christ (Eph. 2:11–22). Their need and the answer to that need are the same. This is why judgment and accountability before God are keys to Peter’s speech.
