CHAPTER 15 describes an important Church council held in Jerusalem around AD 50, just before Paul's second missionary journey. The chapter discusses the issue of whether Gentile converts to Christianity needed to follow Jewish customs, such as circumcision and dietary laws, in order to be saved. The council ultimately decided that Gentiles did not need to follow these customs, but should make concessions to their Jewish brothers and sisters to maintain unity. The chapter also describes the dispute between Paul and Barnabas over whether to bring John Mark on their journey, which resulted in the two going their separate ways.
