It’s a sad enough commentary on the American church that most congregations are mostly white, or mostly African-American, or mostly Hispanic, or mostly middle-class, or mostly blue-collar without willingly and knowingly creating another class of segregation by generation.
The church is most able to represent God’s intention for the world when the grand diversity of the human race is at least partly exhibited in the community assembled at worship.
The purest worship is that which brings together old and young, adults and children, boomers and gen-Xers and the generations that bracket them at the other end.
