The missional church discussion is alternately exhilarating and mystifying for pastors and church leaders. On the one hand, missional church literature addresses trenchant issues in ministry, offering a new vision that moves congregations beyond inward focus and toward participating in the triune God’s renewal of the whole creation. On the other hand, understandings of what constitutes the missional church vary widely. According to some, a missional church is one that has rediscovered the centrality of worship in word and sacrament; others contend that worship is simply a motivational session for individuals who are going out into the world, where they are more likely to encounter Jesus. The fact that a new book comes out every few months claiming to disclose the secret of being truly missional does not necessarily help.
