You do have a point, and there are some benefits in reaching a certain demographic or racial group. But that limits the assembly. If God gives you a certain group, train them to be open to all.

If the righteous approach those demographics that you list and a body of believers come out of it, so be it. I see nothing wrong with a demographic-based church. If there is an issue here, then Jesus Himself should be questioned about his wharf-based group. Do you think the tax collectors were upset when they had to sit on the sand to eat with Jesus?

The important thing to remember here is the meaning of the word “church” – the entire community of all who are called by and to Christ. Whether that group ends up in the sand, on horseback or in a pew is of little consequences.
