That's a bit tongue in cheek. I'm recalling the 1920s proposed merger of the Congregational churches and the Universalist Church. The Universalists got cold feet at what would have been a virtual absorption. The Congos went to merge with the "Christians" (a part of the American movement that includes the Christian Church (Disciples of Christ)) and then to the Evangelical and Reformed Church, and the Universalists went off to the Unitarians.
Well, I've noted how the United Church of Christ has been adding already-existing churches. Two are noteworthy.
- Higher Dimensions Family Church, of Tulsa, Oklahoma. This is the charismatic church led by Carlton Peason, known for his theological universalism. (Previous blog post)
- Church of the Universal Fellowship, of Orono, Maine. This is a Congregationalist-Universalist local merger that was for a long time independent. (I believe it does and has had some kind of contact with the Northeast District, UUA.)
