To me, this is a top ten book. It gives meaning to the word Ekkesia and expresses what meetings of the Ekklesia could and should be in every way. Coming from an "evangelical" semi charismatic background, I read a book like this with the type of excitement, like could it really be. So few understand the Ekklesia because it's been abandoned for more "progressive" approaches. Yet, these "new approaches" leave the veteran believer without means of challenge or growth. You become "old news" and since the kingdom of God means nothing to the average Sunday going to meeting type, what's left other than to warm pews and throw money every weekend.
However, A Third Way, challenges the modern notion of what calls itself church. Lederach articulates that we are the visible Ekklesia and as such, we need spiritual kaizen (continuous improvement). What calls itself church has no means by which to do this. It has no means of developing people other than to put people into functionary roles for a reoccurring weekend play. Lederach talks about dealing with problems, the priesthood of all believers, admonishment, constructive confrontation and all the stuff that helps people to grow.
This book ought to be must reading and study for all believers.
An important book in its time, it describes the Mennonite faith as being neither Catholic nor Protestant. The concerns of the world that the author addresses are different now than when this book was written.
