First, just because your church looks diverse doesn't mean it is diverse.
Second, the multi-cultural ministry is a recipe for conflict.
Third, multi-cultural ministry slows down ministry.
Fourth and finally, being a multicultural church takes a lot of listening.
Maybe too much weight given to the challenges and not enough to the HUGE amount of positive stuff to say about the richness that comes from diversity as well as the challenges
Yet the conclusion is spot on...
"Scripture goes to great lengths to point out the diversity around the throne. Thus, it seems only right and perhaps pleasing to God that our churches might be signs of the kingdom of God today in increasing multiculturalism. I am encouraged by the efforts I see, and challenged to move forward in my own life and church as the conference theme suggested, For the Sake of the Gospel."
Much has proved true at Twynholm Baptist Church, a church of about 75 with 21 nationalities and pretty significant socioeconomic diversity.
But on the positive side I'd go so far to say that it is a gospel imperative to seek to reflect the cultural diversity of the community in which your church meets.
It is interesting in Galatians 3:28 that, where there were divisions between Jew and Gentile, Paul widens the implications of the gospel to undermine ALL natural divisions Jew/Gentile=ethnic, male/female=gender, slave/free=socioeconomic.
This is not an exhaustive list, but his widening the view of potential divisions undermines any other divisions we could think of: young/old, able-bodied/disabled, educated/uneducated, sound mental health / mentally ill. etc. etc. etc.
