At a time when everybody and their brother is beginning to use the word "missional," it's hard to sort through who's just jumping on the bandwagon with the new lingo without embracing a missional way of being, and who is really promoting and seeking to implement the (New Testament) vision for the church that gives rise to the missional church movement in the first place. What's more, those who have embraced a missional vision often find it very difficult to translate that vision into very practical steps that leaders and congregations can take as they seek to be faithful.
One group of leaders that has both participated in the initial formation of the contemporary missional church movement and is doing some very practical things to see it take shape in the lives of congregations is the Missional Leadership Institute. These folks are working with denominational leaders, doing seminars for congregational leaders, writing books, etc., and they understand that missional transformation is an extended process. I commend them to you as a resource.
