Yes. But given how Christians are supposed to believe all people as God's children, self-segregation seems wrong. Churches should be the least segregated of places, shouldn't they?
If Christians really care about the building up of the mystical Body of Christ, they should seek to blend and mingle with those of different races and cultures. What they have in common is something in the new creation in that they share the life of God.
Now no doubt, language, ethnicity, country, even region of the country, forms some lesser bonds of unity in the old creation. But having a vision of the
"one new man" Christians should ask only one important question -
"Has Christ received this person? If Christ has received this person then I must receive this person."
"Therefore receive one another as Christ also received you to the glory of God." (Romans 15:7)
This does not mean that we scold the Spanish brothers for preparing Spanish food in their dinner, or insist that the Japanese saints not speak their language in their worship. Practicality may call for a English speaking meeting because most of the Christians in that meeting speak English. Or practicality may call for a Chinese speaking meeting because most of the participants speak Chinese.
But these are not churches defined by race. They are meetings designated by language. And if the vision of the saints in for the universal Church it is good for them to mingle, blend, unite in spirit with those with whom their unity is based on the life of Christ alone.
