Unitarian Universalism (UUism) is a theologically liberal religion characterized by its support for a "free and responsible search for truth and meaning." Unitarian Universalists do not share a creed; rather, they are unified by their shared search for spiritual growth. Unitarian Universalists draw on many different theological sources and have a wide range of beliefs and practices. Both Unitarianism and Universalism trace their origins to Christian Protestantism and thus Unitarian Universalism has its historical roots in the Christian faith. But by the time they decided to combine their efforts at the continental level, the theological significance of these terms had expanded beyond the traditional Christian understanding. Today’s UUs appreciate and value aspects of other religions ranging from Judaism to Jainism. Although Unitarian Universalist congregations and fellowships tend to retain some Christian traditions, such as Sunday worship with a sermon and the singing of hymns, they do not necessarily identify themselves as Christians, nor do they necessarily subscribe to Christian beliefs. The extent to which the elements of any particular faith tradition are incorporated into one's personal spiritual practices is a matter of personal choice in keeping with Unitarian Universalism's creedless, non-dogmatic approach to spirituality and faith development.
