The Willow Creek style churches have a ‘kingly’ emphasis on leadership, strategic thinking, and wise administration. The danger there is that the mechanical obscures how organic and spontaneous church life can be. The Reformed churches have a ‘prophetic’ emphasis on preaching, teaching, and doctrine.
The danger there is that we can have a naïve and unBiblical view that, if we just expound the Word faithfully, everything else in the church — leader development, community building, stewardship of resources, unified vision — will just happen by themselves.
The emerging churches have a ‘priestly’ emphasis on community, liturgy and sacraments, service and justice. The danger there is to view ‘community’ as the magic bullet in the same way Reformed people view preaching. (Online source)
