Paul Littleton has just finished posting a 3-part series entitled "The Church - A Diverse Body" that dovetails nicely with what I have been writing about here, as of late, at Love Each Stone. I think the issues Paul addresses are not of minor importance for us who take seriously the Word of God and the call of Jesus to radical, obedient discipleship. And, I think Paul does a first-rate job of reflecting responsibly and practically on these matters. I thus recommend you to read and think with an open mind and heart about what Paul has to say...
The Church - A Diverse Body
The Church - A Diverse Body 2
The Church - A Diverse Body 3
Update: Ed Stetzer has also posted some good thoughts on the same basic subject (with a good discussion on the comment string here and here).
While I am at it, Paul links to a document on this issue that is so important and central to what we are to be about in world missions, that I want to post the entire text of the key section here, in the hope that more people will read it, and take to heart what it says.
It is section #5 from Lausanne Occasional Paper 1: The Pasadena Consultation - The Homogeneous Unit Principle...
5. The Church, the Churches and the Homogeneous Unit Principle
We are all agreed that, as there is one God and Father, one Lord Jesus and one Holy Spirit, so he has only one church. The unity of the church is a given fact (Ephesians 4:4-6). At the same time, we have the responsibility to maintain this unity (v. 3), to make it visible, and to grow up into the fullness of unity in Christ (vv. 13-16).
How then can the unity of the church (to which we are committed) and the diversity of cultures (to which we are also committed) be reconciled with one another? More particularly, how can separate HU churches express the unity of the Body of Christ?
We are all agreed that the dividing wall, which Jesus Christ abolished by his death, was echthra, "enmity" or "hostility." All forms of hatred, scorn, and disrespect between Christians of different backgrounds are forbidden, being totally incompatible with Christ's reconciling work. But we must go further than this. The wall dividing Jew from Gentile was not only their active reciprocal hatred; it was also their racial and religious alienation symbolized by "the law of commandments and ordinances." This, too, Jesus abolished, in order to "create in himself one new man in place of two, so making peace" (Eph. 2:15).
This did not mean that Jews ceased to be Jews, or Gentiles to be Gentiles. It did mean, however, that their racial differences were no barrier to their fellowship, for through their union with Jesus Christ both groups were now "joint heirs, joint members of the same body and joint partakers of the promise" (Eph. 3:6 literally). The union of Jews and Gentiles in Christ was the "mystery" which was revealed to Paul and which he proclaimed to all (Ephesians 3:3-6, 9, 10). Thus the church as the single new humanity or God's new society is central to the gospel. Our responsibility is both to preach it and to exhibit it before the watching world.
What did this mean in practice in the early church? It seems probable that, although there were mixed Jewish-Gentile congregations, there were also homogeneous Jewish congregations (who still observed Jewish customs) and homogeneous Gentile congregations (who observed no Jewish customs). Nevertheless, Paul clearly taught them that they belonged to each other in Christ, that they must welcome one another as Christ had welcomed them (compare Romans 15:7), and that they must respect one another's consciences, and not offend one another. He publicly rebuked Peter in Antioch for withdrawing from table fellowship with Gentile believers, and argued that his action was a denial of the truth of the gospel, that is, of the justification of all believers (whether Jews or Gentiles) by grace through faith (compare Galatians 2:11-16). This incident and teaching should be taken as a warning to all of us of the seriousness of permitting any kind of apartheid in the Christian fellowship. And it should go without saying that no one visiting a church or requesting membership in it should ever be turned away on merely cultural grounds. On the contrary, visitors and members should be welcomed from all cultures.
All of us are agreed that in many situations a homogeneous unit church can be a legitimate and authentic church. Yet we are also agreed that it can never be complete in itself. Indeed, if it remains in isolation, it cannot reflect the universality and diversity of the Body of Christ. Nor can it grow into maturity. Therefore, every HU church must take active steps to broaden its fellowship in order to demonstrate visibly the unity and the variety of Christ's church. This will mean forging with other and different churches creative relationships which express the reality of Christian love, brotherhood, and interdependence.
During our consultation we have shared several possible ways of developing such relationships. They will range from occasional united evangelistic crusades, Christian concerts, conferences, conventions and annual festivals through a variety of voluntary associations and interchurch federations to the regular enjoying of intercultural fellowship. One model of this we have looked at is the large city church (or congregation) with several HU subchurches (or subcongregations) which normally worship separately but sometimes together. On these occasions their common celebration is enriched by the dress, music, and liturgy of different traditions. Another model a multicultural Sunday congregation which divides into mid-week HU house churches, while a third and more radical way is to work towards integration, although without cultural assimilation.
In our commitment to evangelism, we all understand the reasons why homogeneous unit churches usually grow faster than heterogeneous or multicultural ones. Some of us, however, do not agree that the rapidity with which churches grow is the only or even always the most important Christian priority. We know that an alien culture is a barrier to faith. But we also know that segregation and strife in the church are barriers to faith. If, then, we have to choose between apparent acquiescence in segregation for the sake of numerical church growth and the struggle for reconciliation at the expense of numerical church growth, we find ourselves in a painful dilemma. Some of us have had personal experience of the evils of tribalism in Africa, racism in America, caste in India, and economic injustice in Latin America and elsewhere, and all of us are opposed to these things. In such situations none of us could with a good conscience continue to develop HU churches which seem to ignore the social problems and even tolerate them in the church, while some of us believe that the development of HU churches can often contribute to their solution.
We recognize that both positions can be defended in terms of obedience—obedience to Christ's commission to evangelize on the one hand, and obedience to the commands to live in love and justice on the other. The synthesis between these two still eludes us, although we all accept our Lord's own words that it is through the brotherly love and unity of Christians that the world will come to believe in him (John 13:35; 17:21, 23).
