Unitarian Universalist Association (UUA), in full the Unitarian Universalist Association of Congregations in North America, is a liberal religious association of Unitarian Universalist congregations formed by the consolidation in 1961 of the American Unitarian Association and the Universalist Church of America. Both of these predecessor organizations began as Christian Unitarian and Universalist denominations; but modern Unitarian Universalists define themselves as non-creedal, and therefore they are not limited to Christian beliefs or affinities, but may also draw wisdom from other religions and philosophies as well, such as Humanism, Buddhism, Judaism, and Earth-centered spirituality, among others, or different combinations of them. Therefore the UUA qualifies as a form of post-Christian liberal religion.
The UUA is not a denomination in the traditional sense; the UUA is an association of congregations. The congregations have authority over the larger body, through the annual General Assembly of the Unitarian Universalist Association. Because of this relationship between the congregations and the association, Unitarian Universalist congregations have a congregational polity of governance. However, for the more day-to-day decisions, there is a Board of Trustees that is elected by Districts and at General Assembly.
In its role as a national organization representing the congregations, the UUA is a member of various organizations, both religious and secular
The Unitarian Universalist Association, is composed of 19 Districts. Each District has its own District-level organization, complete with governing body (in the form of an elected council, or board).
The mission of the UUA Districts is to serve as a resource for local congregations and to help extend Unitarian Universalist influence in the larger community.
The Mid-Columbia Unitarian Universalist Fellowship is a member of both the Unitarian Universalist Association of Congregations (UUA) (UUA website) and the Pacific Northwest District (PNWD) (PNWD website)
