The church refers to the body of Christ which began on the day of Pentecost in Acts chapter 2. It is comprised of Jews and Gentiles who have accepted Jesus as Savior. The church exists universally as an organism, the global presence of Christians who form the body of Christ. The church also exists locally as an organization, a nearby assembly of believers who gather together for Bible study, worship, fellowship, and the practice of the ordinances of baptism and the Lord’s Supper. The Christian church is a mystery not revealed in the Old Testament and is separate from Israel, having a different identity and purpose.
