Here it is...
A few years ago my husband and I took one of the youth from my congregation out to lunch. She had questions, and we were appropriately deemed experts she could turn to in her struggle as she engaged in a yearlong inquiry into leaving the Presbyterian Church to become an Anabaptist.
My husband and I are experts because, as we like to joke, I am an ethnic Presbyterian and he is an ethnic Mennonite, both of us having decidedly chosen as adults to remain in our respective traditions of origin, each of us serving as pastors in those traditions as well.
We came to this lunch armed with all of the historic and modern conflicts between our traditions, ready to entertain and inform her with a friendly point counter-point.
