When Paul uses the phrase ‘the mystery of Christ’ in Ephesians 3:1-13, he is talking about God’s hidden plan being revealed to the world through the Gospel and the Church. Specifically Paul says “This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.” Therefore, in these verses we read of the mystery of Christ, the ministry of the gospel and manifold wisdom of God displayed through the Church. We need to understand how these three M’s fit together if we are to understand God’s hidden plan now revealed.
