From wiki:
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.[2] Both of these predecessor organizations began as Christian Unitarian and Christian Universalist denominations. However, modern Unitarian Universalists see themselves as a separate religion with its own beliefs and affinities. They define themselves as non-creedal, and draw wisdom from various religions and philosophies, including Humanism, Christianity, Hinduism, Buddhism, Judaism, Islam, and Earth-centered spirituality.[3][4] Thus, the UUA is a syncretistic religious group with liberal leanings.
