Reportedly, there are some multi racial/cultural Christian churches in the U. S. and the number is growing. Yet, to predict this will be a vast new experience that sweeps the country seems unlikely.
It will not work for this reason: It assumes the faith is based on “The Word” and all that is required is for different kinds of people to worship together.
The truth is the faith is not based on The Word, but the culture interpreting it. Thus, what the truth of the faith is to any particular individual depends on the person’s culture.
For example, a white Southern Baptist might see today’s religious issues as abortion and gay marriage. A black Baptist would see the great religious issue of our time as social justice.
I’ve read the Republican Party is running into the same problem trying to crack into the hipanic and black voting blocks. Republican leaders see their party as owning the “family values” political franchise which means anti gay marriage and abortion.
What they are running into is the black/hispanic view “family values” mean equal opportunity for their families.
That religious values come from a culture, not from some sovereign source, can be seen in the may images in art of Jesus. Jesus’ race is the same as the people who display it, black, white and brown.
The message of Jesus changes in the same way from one cultural heritage to another. They won’t worship together until they share a common culture.
