Contrary to the hundreds of denominational churches that claim to belong to Christ, Jesus said He would build His church (Matthew 16:18). Christ built only one church and the church was established about A.D. 30 in Jerusalem as reported in Acts chapter 2.  On that day the Holy Spirit came upon the apostles just as the Old Testament prophets had foretold. At that time the apostles preached the Gospel in its fullness in the name of the resurrected Son of God (Isaiah 2:1-4; Joel 2: 28-32; Luke 24:44-49; Acts 2:1-36).  Those responding to that message in faith and repentance were baptized into Christ for the remission of sins and were added to His church (Acts 2:37-47;Galatians 3:26-27).  In the Bible we see that Christ established only ONE church, and if we want to follow Christ we must be in His church (Ephesians 1:22, 23; 4:4; 5:25-27; Colossians 1:18).
