In an unchurched society, people have separated faith from church participation. Many people in an unchurched society identify themselves as having faith but not choosing to participate in a congregation. This seems unacceptable to people living with a churched society mindset, but it is reality for many of the 70 million unchurched people in America. We may not like this, but it is the ways things are now. We must adapt.
People have less loyalty to congregations.
In a churched society people were proud members of a denomination. When they moved, they sought out a church of that denomination. They could tell you the distinctive of their denomination. In an unchurched society some people still care about denominational affiliation and follow the workings of the denomination. But most do not know or care about denominations.
