Is America a Christian Nation? According to author T. Carlos Andersen, the true religion of the land is the confluence of commerce, materialism, and consumerism. Andersen, defining religion as "e;ultimate concern,"e; claims our true devotion is found in material pursuits. It's been a good religion; it has fed, clothed, sheltered, and employed millions of Americans. It can go too far, however. When these pursuits become excessive, the religion breaks bad and the common good suffers.
