Earlham School of Religion functions in tandem with Bethany, a Church of the Brethren seminary, sharing campus space, courses and programs. For example, two of my classes are under the auspices of Bethany. I think this is healthy for Quakers, who can get insular and ingrown and then suspicious of outsiders. Thus I was interested in a blog article on the need for faith groups to widen their "gene pool" at http://biblical.edu/index.php/media/missional-journal: You have to click on the pdf for Founder's Effect. ( I found this through the Jesus Creed site.)
It noted the need for incorporating the message of marginalized groups into the faith discussion, noting that mainstream, evangelical Christianity is dominated almost entirely by white voices and white, middle-class perspectives.
