It seems the term "missional" is one of those current buzzwords in Christian circles. But as buzzwords go, it is a good one. So would Ross Hastings contend. What Hastings writes is not one more handbook or narrative recipe for creating "the missional church". Rather, he writes a missional theology in the truest sense, rooting missionality in the missionality of God. Furthermore, he contends that this flows out of the church's participation in the life of the triune missional God. Hence the title: missional God, missional church.
The book is developed around the text of John 21:19-23, which Hastings calls the greatest commission. Four introductory chapters present the outline of the book, call us into inculturation and out of enculturation, and most of all outline a theology of the missional triune God. The remaining two parts of the book explore the shalom Jesus calls the disciples into and bids them to disseminate.
The great value of the book is that Hastings demonstrates that missional hardly equals shallow and that the missional church and the "deep" church needn't be opposed to one another. Rather Hastings calls for a church that is deep and wide. What I regret is that the style of writing and the depth of the approach will likely consign this book to be read primarily by other missiologists. The language is academic and includes significant excurses into matters such as the current discussions of trinitarian theology. This is regrettable because it seems that a discussion along the lines of this book could be quite significant for the leadership of local congregations--grounding mission not simply in desires for growth or technique, but rather in the greatness of our missional God. It would be a great gift if Hastings would write a sequel focused not toward the academy but toward church leadership.
