Ephesians 3:4–6 — What Does It Mean? | Passage Breakdown

 

📖 Full Passage

 

Ephesians 3:4–6

“by which, when you read, you may understand my knowledge in the mystery of Christ), which in other ages was not made known to the sons of men, as it has now been revealed by the Spirit to His holy apostles and prophets: that the Gentiles should be fellow heirs, of the same body, and partakers of His promise in Christ through the gospel,”

 

Background & Flow from Verses 1–3

 

In the previous post Ephesians 3:1-3— Paul has just established:

 

  • The mystery was revealed to him by Christ
  • The dispensation of grace was given to him
  • This truth was not previously known

 

Now in verses 4–6, Paul does something critical:

 

➡️ He defines exactly what the mystery is

 

Phrase-by-Phrase Breakdown

 

“by which, when you read…”

 

Paul expects this truth to be:

 

  • Read
  • Understood
  • Grasped clearly

 

This was not retroactively understood before.

 

It was hidden in God until Paul.

 

Retroactively forcing Paul’s revelation into the four Gospels and Acts 1–2 is a man-made bridge—born of desperation—propped up by eisegesis, not exegesis.

 

➡️ It is now written revelation

 

“…you may understand my knowledge…”

 

Paul is not claiming superiority—he is stating:

 

➡️ He has specific, revealed knowledge

 

This knowledge came directly from:

 

  • Christ (Galatians 1:11–12)
  • By revelation—not tradition
  • Not from Peter and the 11

 

“…in the mystery of Christ)”

 

This phrase is precise.

 

Not:

 

  • The mystery about Christ’s existence
  • The mystery of the cross alone

 

But:

 

➡️ The mystery belonging to Christ’s heavenly program

 

This is distinct from:

 

  • Israel’s prophetic program
  • The earthly kingdom promises

 

“which in other ages was not made known…”

 

This is one of the most important doctrinal statements in Scripture.

 

Paul does not say:

 

  • “Not fully known”
  • “Not clearly understood”

 

He says:

 

➡️ NOT MADE KNOWN

 

Meaning:

 

  • Not revealed to Abraham
  • Not revealed to Moses
  • Not revealed to the prophets
  • Not revealed during Christ’s earthly ministry

 

“The retroactive application of Paul’s letters to the four Gospels and Acts 1–2 is a man-made construct—manufactured in desperation—driven by eisegesis rather than faithful exegesis.”

 

“…to the sons of men…”

 

This includes:

 

  • All previous generations
  • All prophets
  • All writers of the Old Testament

 

➡️ No one had this information prior

 

“…as it has now been revealed…”

 

This marks a dispensational shift

 

  • Then: Hidden
  • Now: Revealed

 

Not progressively uncovered—

 

➡️ Suddenly revealed

 

Good men—pastors, elders, and friends of mine—insist that what was revealed to Paul was not wholly unknown to Peter, James, and John, but only partially understood. They claim the doctrines of grace were already there, only waiting for Paul to clarify and complete them.

Beloved, read Ephesians carefully. Read chapters 1, 2, and 3 over and over, taking God at His word—not the word of your denomination, your tradition, or your favorite theologian. Then decide for yourself what the ascended Lord Jesus is saying through the pen of the apostle Paul.

 

“…by the Spirit…”

 

The source is divine:

 

  • Not theological development
  • Not human interpretation

 

➡️ The Holy Spirit revealed it

 

“…to His holy apostles and prophets:”

 

This is often misunderstood.

 

These are not the Twelve 

 

These are:

 

➡ ️ Paul’s companions Timothy, Silas, and Barnabas.

 

Connected to:

 

  • Ephesians 2:20
  • The foundation of the Body of Christ

 

Key point:

 

👉 They received this from Paul, through Paul
👉 Not before
👉 Not during Christ’s earthly ministry

 

“that the Gentiles should be…”

 

Now Paul defines the mystery in plain terms.

1. “fellow heirs”

Equal inheritance

 

Not:

  • Secondary
  • Not blessed through Israel’s rise

 

➡️ Equal standing

 

2. “of the same body”

 

This is massive.

 

Not:

 

  • Israel + Gentiles
  • Not two groups

 

➡️ ONE BODY

 

This body did not exist in prophecy. 

There was no message of salvation to Gentiles between the call of Abraham in Genesis 12, and the call of Paul in Acts 9. The Gentile world was without hope, without Christ Ephesians 2:11.

 

3. “and partakers of His promise…”

 

Key word: partakers

Not:

 

  • Replacing Israel
  • Taking Israel’s promises

 

➡️ Sharing in spiritual blessings in Christ

 

Gentiles can now freely partake in the blessings promised to Abraham by believing the gospel.

 

👉 Partakers, not takers

 

“…in Christ…”

 

This phrase defines the entire dispensation:

 

  • Our position
  • Our identity
  • Our blessings

 

➡️ All are in Christ, not in Israel

 

“…through the gospel,”

 

Which gospel?

 

Not:

 

  • The kingdom gospel
  • Not repentance for national restoration

 

➡️ The gospel of grace (1 Corinthians 15:1–4)

 

Doctrinal Summary

 

Ephesians 3:4–6 explicitly defines the mystery:

 

1. The Mystery Was Completely Hidden

 

Not partially known
Not predicted

 

➡️ Not made known in other ages

 

2. The Mystery Is Now Fully Revealed

Through:

 

  • The Holy Spirit
  • Given first to Paul
  • Then communicated to others

 

3. The Mystery = One Body, the Body of Christ

 

Not Israel expanded
Not Gentiles added to Israel

 

➡️ A completely new organism

 

4. Gentiles Are Equal Participants

 

  • Fellow heirs
  • Same body
  • Partakers

 

➡️ No distinction in position

 

5. This Is Not Israel’s Program

 

This was never promised in:

 

  • The Abrahamic Covenant
  • The Davidic Covenant
  • The New Covenant

 

➡️ This is mystery truth, not prophecy

 

Final Summary

 

Ephesians 3:4–6 is one of the clearest definitions of the mystery in all of Scripture.

 

It confirms:

 

  • The mystery was not known in any previous age
  • It is now revealed by the Spirit
  • It forms a completely new body
  • Gentiles are equal participants, not second-class or attached to Israel

 

These passages clarify:

 

  • Replacement theology is a false teaching
  • The Church, the body of Christ began with Paul
  • The claim that the apostles were all preaching the same message is impossible

 

Instead, it establishes:

 

➡️ A new dispensation
➡️ A new revelation
➡️ A new identity: members imparticular in the Body of Christ
