I have always found the Shakers, Amish, Quakers, and Mennonites fascinating. I was surprised the Shaker membership had dropped to TWO seniors- no wonder I never met one in field Service.
My wife's (3rd Gen) German maternal ancestors were from a Germanic Mennonite/Lutheran group.
When I first went to Bethel, I almost expected an almost ascetic environment. I was quickly disabused of that notion after my first week of breakfast announcements of "family member" disfellowshippings. :)
