Here at the office following an amazing experience. Four college-aged persons arrived unannounced at the church door, wanting a tour. They were from the Columbia, Maryland suburb, and one of the four knew about Unitarian Universalism. (Her parents had been married in a San Francisco Bay area UU church.)
They were interested and keen, especially when the talk moved from the architectural to the theological. (We have a John Murray memorial window, and I tell his landing story, with the "Not hell, but hope and courage" ancedote.)
Seems they are part of a collegiate ministry to the city, and they wanted to pray with me for the church, my ministry, "that you Father might send [me] a new word" and the city.
They were positive, affirming, and open for us to participate in the ministry to disadvantaged children in a local park. I liked these people, and they seemed to appreciate an open door.
But there's another lesson here: connections — and especially the ecumenical contact that so many Unitarian Universalist Christians crave — will follow the same rules as the post-Constantinian church. The connections will be lateral and personal. (Not unlike this blog.)
We don't have to wait to be welcomed by the ecumenically-assertive denominations (indeed, it may never happen) but contact may be as close as the front door.
