Anyone who has had any contact -- post-Jesus Music era -- with American evangelicalism will know the lyrics of the classic campfire song, "We are One in the Spirit." Some people may know this song under a different title, "They'll Know We are Christians by Our Love."

One thing is for sure, no doubt about it. The word "Spirit" in this song definitely has an upper-case "S," representing -- even under Associated Press style rules -- a reference to the Holy Spirit, one Person in the traditional Christian Trinity. The first verse of this famous song goes like this: 

We are One in The Spirit, We are One in The Lord. 

We are One in The Spirit, We are One in The Lord. 

And we pray that all unity may one day be restored.

And they'll know we are Christians by our love, by our love, 

Yes they'll know we are Christians by our love.

Now, I bring this up because of a very interesting musical reference at the end of the latest in a long list of Baltimore Sun stories written as tributes to brave progressive Christian congregations -- defined as those with doctrines acceptable to editors at the newspaper that lands in my front yard -- that are fighting to remain alive here in Charm City. In this case, we are dealing with a story about three congregations that are sharing a building in West Baltimore, in an attempt to make ends meet.
