A very interesting book. Author distinguishes between the NT church at Jerusalem and the NT church at Antioch. He argues that the Jerusalem church was based on continuity with the Mosaic law and tended to look backward to determine and maintain its identify. The Antiochian church, however, took its identity from Christ and the Holy Spirit and was more future looking and emerged over time with a different theology, focus, and mission. The author argues that contemporary "emergent" churches should be looking to the Antiochian church for their identity and practice. An enjoyable, thought provoking, scholarly read.
