The human dimension is an essential feature of the church. The church is a gathering of people. It is not simply a divine idea or the divine dimension by itself. The church exists only as the divine and human are united in one community. In the New Testament, the ekklesia or church is called an assembly, a people, a nation (1 Pet 2:9), and a family (Gal. 6:10), each denoting human beings in community. The church, then, becomes visible in the world in a community of living human beings.

There are many kinds of assemblies and communities. The church is a people called together by the Spirit of God to live in Christ for the praise and service of God. But the church could not exist apart from a human response to that call. The most basic response is faith. Apart from a believing embrace of the message of Christ, repentance, baptism, and other churchly activities make no sense. Faith moves us to turn away from our old lives and mark that transition by receiving baptism, which is pictured in the New Testament as a spiritual washing (Acts 22:16) or a death, burial, and resurrection with Christ (Rom 6:1-7).

The transition from nonbelief to belief and its symbolic enactment in baptism is at once a transition from not being a Christian to being one and from not being a member of the church (or family or people) of God to being including in this people. Becoming a member of the church is not an add-on to becoming a Christian but happens simultaneously and is co-essential. It makes no sense to think one could be “in Christ” but not part of the body of Christ, a child of God but not a member of God’s family.

What is the Church?

Until this point in the series I have used the term “church” without defining it. For until we uncover the essential features of the church—that is, those factors that determine the difference between its existence and nonexistence—we cannot define it with precision. What, then, is the church? The church consists of those people who in obedient faith and by baptism have been incorporated into Christ through the work of Holy Spirit and so have become one body, one people, one family.

Wherever these factors are present, the church in its fullness exists. Once the church exists and begins to act, other factors come into play. Some means will be chosen to organize its life and work. Language and culture, too, will place their stamp on the outward forms of church life. But it is important not allow the historical and contemporary forms the church to hide the simple essence of the church. List any factor you please—clergy, systems of organization, property, employees, legal recognition, social visibility, tax exempt status—none are essential. Sweep them all away and the church exists still. The church is simple in essence and, hence, very adaptable in form.

The Individual Christian and the Church

Since New Testament language about the church envisions a community that gathers and acts as one at least on occasion, certain questions naturally arise in our individualistic culture: (1) does the church exist in each individual? (2) Or, does the church exist only when formally and intentionally gathered “as the assembly”? (3) If you were the only Christian left alive in a nation or in the whole world, would the church still exist? (4) Lastly, assuming the church exists even when not gathered formally, must an individual Christian gather regularly with other Christians as the church?

The answers to these four questions are implicit in the definition of the church: (1) Yes, the church exists in each individual believer. Each believer is called by God, lives in Christ, and participates in the life of the Spirit. The divine and human dimensions are united even in an individual Christian. (2) No, the church does not cease to exist when not assembled as a group to act corporately. Christ and the Spirit are not divided by distance. (3) Yes. The church would exist if you were the only Christian in the world. (4) Yes. Though individual Christians can act as members of God’s special people even when not with other believers—in prayer, praise, study, and service—the love of God poured into their hearts by the Spirit (Rom 5:5) will drive them into fellowship with others who share that same compelling love. The gathering is a manifestation in the present of the unity of all things in Christ “when the times reach their fulfillment” (Eph 1:10). And it can be so beautiful!

Next Time: We have not yet addressed the church’s divinely assigned work and purpose. In these areas, too, we will distinguish between essential and accidental features. What is the essential work and purpose of the church? Hint: it, too, is very simple.
