Whose culture determines how you do life together? That’s who your community is really serving. I’ve never heard of a church planting team setting out “to plant a white church.” They have no overt hostility toward any particular group. But in the way they structure their community life together, the “language” they’re speaking is white culture.
“What are some ways that I can connect with a diverse group of people, even though I mostly interact with people who are similar to me?”
It’s easy to rush into things with an idealized attitude of what cross-cultural relationships are like; instead, buckle up for a bumpy ride. There will be difficult dynamics.
