I used to think progressive and emergence Christianity were more or less the same. But according to Phyllis Tickle, they are not. There are key differences…
on justice matters:
In dealing with matters of social justice, the Progressive stance and course of action generally are first intellectualized, then politicized, and finally formalized. By contrast, the Emergence posture or approach is far more pedestrian and humble in both its articulation and its delivery. Emergence Christians will defend vigorously their position that as long as some act of social justice has been a matter of “our doing something for them,” the act is fundamentally one of enlightened or informed self-interest, if not plain old commonsense. Social justice, Emergence contends, really is—really must be—an exercise in “us helping each other” in whatever way possible here and now because of the bond of commonality that is Christ in all of us.
and in their approaches to the Bible:
Almost as remarkable is the way in which the operative approach to Scripture differs between the two groups. The Progressive stance, once again, is far more intellectualized than is that of Emergence. Born in a time of burgeoning Pentecostalism, Emergence Christianity and Emergence Christians are naturally inclined—increasingly so, in fact—toward the approach of communal discernment and direct appeal to the Holy Spirit for explication and direction. Such a stance allows Emergence to be more or less innocent of biblical literalism and far more inclined toward a kind of apophatic or Orthodox actualism.
So emergence Christianity is pedestrian and humble, communal and Spirit directed.
