The first Council of Jerusalem
The First Council of Jerusalem appears in the Bible in chapter 15 on the book of the Acts of the Apostles. It is a meeting between those responsible for the Church of Jerusalem, and Antioch. That meeting was motivated by the problem that arose among the first Christians because some of the sect of the Pharisees, who had embraced the faith, wanted to force non-Jews to circumcise and keep the law of Moses.
Then a strong discussion arose between Paul and Barnabas against them, so the brothers determined that Paul, Barnabas, and some others go up to Jerusalem to deal with this matter. After discussions Peter, Paul and James having given testimony, they resolved with the help of the Holy Spirit that non-Jewish believers were completely exempt from the law of Moses. Thus, the Jerusalem Council resulted in the triumph of Christian freedom.
