Revisiting Hirsch/Stetzer Missional Ecclesiology

We had a great discussion in a previous post trying to figure out which should take priority in determining a missional ecclesiology—missiology or ecclesiology? Both Stetzer and Hirsch have kindly provided their schematics to help clarify their positions. Stetzer writes:

My point is that scripture sets the agenda and has provides direction for all three– one does not “come from” the other but they are all derived from scripture, interact with each other, etc

Ed Stetzer

Hirsch explains: We believe that Christology is the singularly most important factor in shaping our mission to the world and the forms of ecclesia and ministry that form that engagement…Before there is any consideration given to the particular aspects of ecclesiology, such as leadership, evangelism or worship, there ought to be a thoroughgoing attempt to reconnect the church with Jesus; that is, to ReJesus.

Alan Hirsch

Stetzer sets Scripture as the starting place and Hirsch begins with Jesus. What are the implications for these slightly different starting places? Do these differences matter?
