I've been reading Mike Frost's Exiles (p. 136-57), and he says that most new churches today, in the non-west (where the church is growing) are in a large part nondenominational, nonstructured, and nontraditional. David Barret and Todd Johnson, researchers in evangelism and mission called these kinds of churches "neo-apostolics" (2001). As of 2001, Barret and Johnson estimated that neo-apostolics numbered 20, 000 movements & networks including 394 million Christians and will grow to over half a billion believers by the year 2025.
Frost writes (p. 136) that the neo-apostolic movements are "marked by four primary characteristics:
1. They reject denominationalism and restrictive, overbearing central authority.
2. They seek a life focused on Jesus.
3. They seek a more effective missionary lifestyle.
4. They are one of the fastest growing movements in the world."
