The Purpose and Ministry of the Body of Christ
Question
What is the purpose of the body of Christ?

Answer
The body of Christ is the “one new man” of Ephesians 2:15, formed out of both Jews and Gentiles and not identical with Israel. It is not enlarged Israel, not a substitute for Israel, and not Gentiles grafted into Israel. It is a new entity, composed of individuals who receive the gift of eternal life by grace through faith in the gospel revealed to Paul, with Christ as the head and believers as members of his body.
The question is whether Scripture gives a specific purpose statement for this body.
The Ministry of Reconciliation
The clearest purpose-related passage is 2 Corinthians 5:18-20:
“And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God.”
Here we see:
God has reconciled us to himself by Jesus Christ.
He has given to us the ministry of reconciliation.
He has committed to us the word of reconciliation.
We are ambassadors for Christ, appealing to others to be reconciled to God.
Assuming that the “us” here appropriately includes members of the body of Christ (and not merely Paul and his immediate companions), this passage functions as a purpose statement: the body of Christ is entrusted with the ministry and word of reconciliation and serves as Christ’s ambassadors in the world, proclaiming that reconciliation is available.
Other Passages Often Cited
Other texts are sometimes used as purpose summaries, but they must be handled carefully.
The so-called “Great Commission” (Matthew 28:19-20) is commonly treated as the church’s purpose statement: evangelism, discipling, baptizing, and teaching. However, that commission was given to the apostles in the context of Israel’s kingdom program and is not presented in Scripture as the charter of the body of Christ.
Ephesians 2:10 (“we are his workmanship, created in Christ Jesus unto good works”) is often cited. Yet the shift from “ye” in verse 8 to “we” in verse 10 suggests a change of referent, and in Ephesians the “we” consistently aligns with the Jewish remnant, not the broader body of Christ.
Ephesians 3:8-11 describes Paul’s particular commission “to make all men see what is the fellowship of the mystery” and indicates that through the church the manifold wisdom of God is made known to heavenly principalities and powers. While this directly states Paul’s mission, it also reflects what the body of Christ displays: the revelation of the mystery and the demonstration of God’s manifold wisdom. This harmonizes with, and is encompassed by, the ministry of reconciliation in 2 Corinthians 5.
Taken together, the body of Christ proclaims the previously hidden mystery gospel and the reconciliation now available to all.
Avoiding Over-Systematization
There is a danger in forcing a single, narrow “purpose statement” on the body of Christ as if it were a modern corporation. When we do this, we risk excluding many legitimate aspects of Christian life and ministry that are not easily subsumed under that one phrase.
If we said, for example, “the sole purpose of the body of Christ is to proclaim reconciliation,” we might be tempted to downplay or neglect mutual edification, worship, prayer, fellowship, service to one another, and countless expressions of life together that Scripture assumes and commends.
It may be better to see the ministry of reconciliation as a central entrusted task, while recognizing that the body of Christ also exists simply to be Christ’s life on earth: believers joined to their head, walking together, building one another up, and manifesting the reality of that union in many ways.
A Balanced Statement
In light of the passages considered:
The body of Christ is the one new man in which believing Jews and Gentiles are united in Christ.
Its central entrusted task is the ministry and word of reconciliation, functioning as Christ’s ambassadors to the world (2 Corinthians 5:18-20).
Through this body, the fellowship of the mystery and the manifold wisdom of God are made known (Ephesians 3:8-11).
At the same time, the body of Christ lives out its identity in worship, mutual edification, service, and shared life, as those joined to their head and to one another.
So the purpose of the body of Christ can be summarized as bearing and proclaiming the message of reconciliation revealed in the mystery, while embodying the life of Christ together as his corporate body in the present age.
