Unitarian Universalism does not hold one particular religious text to be the most sacred or authoritative. Members use sacred texts from a variety of traditions or none at all, but the Bible is the most commonly used sacred text.
The Unitarian Universalist Association website says the following about sacred texts:
In most of our congregations, our children learn Bible stories as a part of their church school curricula. It is not unusual to find adult study groups in the churches, or in workshops at summer camps and conferences, focusing on the Bible. Allusions to biblical symbols and events are frequent in our sermons. In most of our congregations, the Bible is read as any other sacred text might be-from time to time, but not routinely. We have especially cherished the prophetic books of the Bible. Amos, Hosea, Isaiah, and other prophets dared to speak critical words of love to the powerful, calling for justice for the oppressed... We do not, however, hold the Bible-or any other account of human experience-to be either an infallible guide or the exclusive source of truth. Much biblical material is mythical or legendary. Not that it should be discarded for that reason! Rather, it should be treasured for what it is. We believe that we should read the Bible as we read other books (or the newspaper)-with imagination and a critical eye. We also respect the sacred literature of other religions. Contemporary works of science, art, and social commentary are valued as well. We hold, in the words of an old liberal formulation, that "revelation is not sealed." Unitarian Universalists aspire to truth as wide as the world-we look to find truth anywhere, universally.
