These homogenized Christian spokespersons mean people who look and are like one another. That's not church building. It may be church growth because it is the easy way out. Men's and Women's Clubs and Country Clubs have known that for a long time. We are to be ambassadors of reconciliation, not separation.
Homogeneity implies separation.
One can't maintain homogeneity without separating from those who are different from them. Unity in diversity is much harder to accomplish. Many will take the easy way out and conform to the world's standards. In that case the church is not an example or a role model but a meek little pussy cat that may look successful but is full of dead bones. The church, I am convinced, should speak to a new creation in love.
