A good article in The Christian Century on “Anglican Angst” and the Anglican Mission in America (AMiA, connected with Rwanda’s Anglican Church) and their leaving the Episcopal Church. The result, at least around Chicago, has been split after split after split.

Here is the concluding paragraph:

Theologians from Augustine onward have insisted that the effort to leave one church to start a better one results not in a better church but a worse one—and it also fosters the bad habit of defection. The history of Western Christendom attests to the wisdom of this view. The question for the Anglican Mission in the Americas is whether antagonism toward the Episcopal Church is enough to shape a coherent Anglican identity in a complex global setting.
