It's a bit of an overstretch -- after all, I have an interest in Stanton Coit and denominational data generally -- but I only write substantively about Christianity in the UUA. I write about worship in Christian terms. I write about mission in Christian terms. I write about connections among Unitarian Universalist Christians, and in ecumenical settings. I write about problems Christians have.
What about everyone else?
Well, for one thing, I know more about Christians than other Unitarian Universalists. There are fewer Christians, so there are fewer people to write. Many are personal friends. I am a member of a Christian church that's a member of the UUA. And Christians make up a small minority among Unitarian Universalists.
For another, much of what I write applies to other Unitarian Universalists, especially since our habits and opportunities rest on a common foundation. If you're willing to apply it to your own situation, you might discover some insights. (Christians are asked to translate meta-narratives all the time; it can be done.)
But the most important reason, is that I want to cultivate a particular voice that speaks consistently and predictably to and from the faith situation I dwell in. Unitarian Universalist Christians, while often spoken of as a singular group, really is remarkably diverse in theology, applied polity, politics and life situations.
There's enough of a there there to give it some focus, to support the faithful and upbuild the body. I hope to do this by writing. I hope many people find this valuable (including non-Unitarian Universalist Christians) and it seems to be the work God has set out for me. It's enough without planning to speak for or about those with whom I have a too-thin understanding.
