Possibly the most significant theological advancement that my dissertation, neé book (The Church Is Flat: The Relational Ecclesiology of the Emerging Church Movement) accomplishes is in chapters four and five, in which I look at the ecclesiology of German theologian Jürgen Moltmann and put it into conversation with the ecclesial practices of the emerging church movement (ECM). Further, I believe mine is the first published work to deal with Moltmann’s most recent book, Sun of Righteousness, Arise!: God’s Future for Humanity and the Earth.
Moltmann’s ecclesiology, although spelled out at length in his third major book, The Church in the Power of the Spirit: A Contribution to Messianic Ecclesiology, is largely ignored by the theological academy. I have a theory about why that is: Because, unlike much of Moltmann’s theology, his ecclesiology is eminently practical.
But before getting to that, a quick primer on Moltmann’s overarching theological project is in order.
