Context: Ephesians 3:1-13 explains the "mystery" hidden for ages but now revealed: Gentiles are full participants in the body of Christ. Paul describes himself as prisoner of Christ Jesus "on behalf of you Gentiles" (v. 1), having received grace to preach "the unsearchable riches of Christ" to the Gentiles (v. 8). Verse 6 is the crux: three compound words beginning with σύν (syn, "together with") emphasize Gentile equality with Jewish believers—fellow heirs, fellow members, fellow partakers.

Connection Method(s): Promise-Fulfillment, Redemptive-Historical Progression — The mystery revealed in Christ is that Gentiles are "fellow heirs, members of the same body" as Jews, accomplished through the cross which broke down the dividing wall and created "one new man" in Christ.
Christological Connection: Ephesians 2:14-16 explains how Christ accomplished Gentile inclusion: "For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace, and might reconcile us both to God in one body through the cross, thereby killing the hostility." The cross is the mechanism. Christ's death:
The trajectory: Genesis 12:3 promises blessing to all families → Prophets anticipate nations worshiping at Zion → Christ dies and rises, breaking down the wall → Gospel proclaimed to Gentiles → Gentiles believe and are incorporated as equal members → Church becomes "fellow heirs, fellow body members, fellow partakers" → Revelation 7:9 consummates (great multitude from every nation). What was mystery is now manifest: "Christ in you, the hope of glory" (Colossians 1:27) applies to Gentiles as much as to Jews. The συγ- (syn-) prefix words in Ephesians 3:6 are the linguistic embodiment of Christ's prayer in John 17:21: "that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us." The multinational Church is the visible demonstration of the mystery, the proof that God's promise to Abraham is fulfilled, and the preview of the eternal multinational multitude worshiping the Lamb.
