The mystery of the church, as revealed by Paul, is based on God’s eternal plan that includes both Jews and Gentiles as one body in Christ.
The Apostle Paul emphasizes that the mystery he discusses in Ephesians is the inclusion of Gentiles into the body of Christ alongside the Jews. In Ephesians 3:4-6, he states that this mystery, once hidden, has now been revealed by the Spirit, affirming that Gentiles are fellow heirs and partakers of the promise. The truth of this mystery is solidified through the prophetic writings and the work of Christ, who broke down the barriers that once separated people. As Paul articulates in Ephesians, this revelation is not a new concept but a fulfillment of God's eternal covenant to unite His people under one head, Jesus Christ.
