Separate, but Equal Cultures?

Is the end result of Postmodernity separate but equal or integration? I understand Postmodernism as a rejection of a single meta-narrative and a celebration of the many big-stories. Rather than a single monolithic culture, the local and particular cultures are held in esteem. If we reject a single, integrating culture, are we not proposing of separate, but equal cultures?

I am quickly seeing that I am ministering to two different cultures. The first is the churched kids. Their parents are either church members or are involved at church in some way. There are a couple of exceptions. These students are sheltered intentionally, some more extreme than others. This makes them awkward around their unsheltered peers.

The other group is made up of unsheltered and unchurched kids. Some of them are  from nominally religious homes or have parents who occasionally attend. They are more likely to do "bad things," whether that is swearing, drinking, doing drugs, or having sex. Many have no boundaries set, and the ones who do, are more comfortable with those who don't. This group is no less spiritual and in many ways are more open to the gospel than "the good kids." Clearly, these two groups are at odds.

The "bad kids" are uncomfortable around the "good kids," and vise versa. Each group is culturally different, at least on a micro scale. There is at least enough of a cultural divide that keeps both groups from normally interacting. (I realize there are other factors.)

Missiologically, I believe that each culture should genuinely express Christianity. Navajos should worship in a way that makes sense to them, Ghanians should worship as they see fit, and so should Germans. There will be some overlap, but I expect a Navajo worship to look different from a service in Ghana or in Germany. Language, songs, instruments, liturgy, and mannerisms are (or should be) different. Diversity is a good thing.

So how far should we take this? There are few people who think that a worship service should be multilingual. There are Korean, Spanish, and English speaking people in many communities. I have never heard a trilingual church. Occasionally bilingual is acceptable. The ideal seems to be a separate Spanish meeting and a separate English meeting. How is this not separate but equal? The alternative is to pick a language… say Latin, to unify our worship. So is there middle ground? Are these the only two choices?

When it comes to micro-cultures, do the same rules apply?
