Diversity in the Balance

One of the conversations in the air at Unity Church is the value of diversity and the need to become a more diverse community. This is not a new conversation, and this desire is encapsulated in the ends statements of five years ago. So when I encounter stories of other churches which have become more diverse, such as this New York Times article, I pay attention, even when they are vastly different from this Saint Paul setting.
Briefly, the NYT story describes the transformation of Clarkson Baptist Church in suburban Altanta, a dying all-white traditional southern church, into Clarkson International Bible Church, a growing multicultural church.
Certainly the theology of this conservative evangelical Southern Baptist congregation is quite foreign to that almost all Unitarian Universalists would espouse, but that's not the point. The church saw in their theology a need to reach out to a growing community of African and Philippine and Vietnamese immigrants, and they responded to this call, though not without internal conflict.
Do we UUs find in our broad theological base a similar commitment to invite into the community all who might need us?
The diversification of the Clarkson church was a result of a confluence of several factors. The surrounding community became a settling place for large numbers of immigrants over the last few decades, much as parts of the Twin Cities have become. Initially the church rented out space to separate immigrant congregations which worshiped in their own styles and languages. This brought close, but 'safe' contact. But inviting some of these immigrant churches into the main worship meant change and conflict. Some people left, and those who stayed find they miss some things lost, like the older hymns and sermon styles.
Would UU congregations be willing to give up that much? Would welcoming others of many cultures, with their diverse ambitions, experiences and hopes more than balance out those losses? I do this work in fervant belief that it will be so. As I write this, my iTunes begins pumping out Zimbabwean John Chibadra's "Zuva Refuka Kwangu", a small reminder to me that it will be so.
