If we talk about Acts 15 in detail,

Acts 15 is a famous chapter about the Council of Jerusalem. The conference was held to resolve the debate over whether Gentiles should observe Jewish laws, including circumcision, when adopting the Christian faith. The main points are as follows:

1. Controversy in Antioch (Acts 15:1-2)

• The controversy begins : Some men from Judea came to Antioch and taught the Gentile believers, “Unless you are circumcised according to the custom of Moses, you cannot be saved.”
• Opposition between Paul and Barnabas : Paul and Barnabas argued fiercely over this issue, and decided to go to Jerusalem, where the apostles and elders were, to resolve the issue.

2. Council of Jerusalem (Acts 15:3-21)

• Arrival in Jerusalem : Paul and Barnabas pass through several cities and arrive in Jerusalem, reporting what God has done among the Gentiles.
• Convening a meeting : The apostles and elders gather to discuss the issue.
• Claims of Pharisee believers : Some Pharisee believers in Jerusalem claim that Gentiles must also be circumcised and keep the Law of Moses.
• Peter's remarks : Peter mentions the incident in which the Holy Spirit came to the Gentile Cornelius, emphasizing that God gave the Holy Spirit to Gentiles without discrimination. He says, “Why should we put God to the test, putting on the neck of the disciples a yoke that neither our fathers nor we were able to bear?” He declares that even Gentiles are saved through faith.
• Report of Paul and Barnabas : Paul and Barnabas describe the signs and miracles they performed among the Gentiles.
• James' conclusion : James quotes the prophecy of the prophet Amos and says that it is God's plan for the Gentiles to return to God. He proposes not to burden Gentile believers, but advises them to avoid food offered to idols, blood, things strangled, and fornication.

3. Delivering resolutions (Acts 15:22-35)

• Writing a letter : The apostles and elders write this decision in a letter and send Judas and Silas, along with Paul and Barnabas, to Antioch to convey this information.
• Contents of the letter : The letter states that Gentile believers do not need to be circumcised, but only need to observe four prohibitions.
• Welcome in Antioch : The church in Antioch is delighted to receive this letter, and Judas and Silas give them words of comfort and encouragement. Afterwards, Paul and Barnabas continue to teach the word of the Lord in Antioch.

4. Conflict between Paul and Barnabas (Acts 15:36-41)

• Preparation for the second missionary journey : Paul suggests to Barnabas that they visit each city and see how the brothers are doing.
• The John Mark Problem : Barnabas suggests taking John Mark with him, but Paul objects, citing what happened to Mark on his previous trip.
• Breakup : This causes severe conflict between Paul and Barnabas, and eventually the two decide to go their separate ways. Barnabas takes Mark to Cyprus, and Paul travels to Syria and Cilicia with Silas to strengthen the church.

conclusion

Acts 15 addresses an important theological issue facing the early church and concludes that Gentile believers do not need to keep Jewish law. This marks an important turning point in the development of Christianity from a branch of Judaism into an independent belief system. Additionally, the conflict between Paul and Barnabas shows the human side and well represents the process by which God's work is accomplished through various people.
