What message marks the beginning of the body of Christ?

Les explains that the body of Christ came on the scene in the New Testament, but he is convinced it did not necessarily begin at Pentecost, because Pentecost was strictly a Jewish holiday with a Jewish message. He ties the body’s beginning to the gospel going out to Jew and Gentile, especially at Antioch in Acts 11, where believers were first called Christians. Les teaches that the body began when Paul began preaching Christ’s death, burial, and resurrection, and salvation by faith, faith alone, without the law. As men and women believed that message, the Holy Spirit baptized or placed them into the body of Christ. He also asks whether every member on a church roll is genuinely born again.
