Some men come down from Judea to Antioch and teach the brothers that unless they are circumcised according to the custom of Moses, they cannot be saved. Paul and Barnabas dispute with them, and the church sends them to Jerusalem with others to discuss the matter with the apostles and elders. On the way they tell the churches of the Gentiles' conversion, to great joy. In Jerusalem, some believers who belonged to the party of the Pharisees say that Gentiles must be circumcised and told to keep the law of Moses.
After much debate, Peter recalls that God chose him so that the Gentiles would hear the gospel, and that God gave them the Holy Spirit just as he did to them, cleansing their hearts by faith. He asks why they would test God by putting on them a yoke that neither their fathers nor they could bear, and concludes that they are saved through the grace of the Lord Jesus, just as the Gentiles are. James, the brother of the Lord, cites Amos about the rebuilding of David's tent so that the Gentiles may seek the Lord. He proposes not to trouble the Gentiles who turn to God, but to write them to abstain from things polluted by idols, from sexual immorality, from what has been strangled and from blood.
The apostles, elders and the whole church decide to send Judas Barsabbas and Silas to Antioch with Paul and Barnabas, with a letter saying they do not wish to lay on them any greater burden than these necessary things. The brothers in Antioch rejoice when it is read.
After some time, Paul proposes visiting the churches of the first journey. Barnabas wants to take John Mark, but Paul does not, because he had deserted them. The disagreement is so sharp that they part company: Barnabas takes Mark and sails to Cyprus, and Paul chooses Silas and goes through Syria and Cilicia, strengthening the churches.
