Harry Ironside addresses the misconception that the Apostle Paul received the revelation of the mystery of the one Body only during his imprisonment in Rome. He argues that Paul had been preaching this mystery since his conversion, as evidenced by his earlier letters, particularly Romans, Corinthians, and Galatians, which affirm the unity of believers in Christ. Ironside emphasizes that the mystery was not exclusive to Paul but was revealed to other apostles and prophets, including Peter and John, and that it signifies the abolishment of distinctions between Jews and Gentiles in Christ. He asserts that the Body of Christ was formed through the Holy Spirit's baptism, and this truth was consistently taught throughout Paul's ministry. Ultimately, Ironside defends the integrity of Scripture against those who distort its message to fit their theological frameworks.
