Unitarian Universalism (UU) is a liberal religion characterized by a "free and responsible search for truth and meaning". Unitarian Universalists assert no creed, but instead are unified by their shared search for spiritual growth, guided by a dynamic, "living tradition". Currently, these traditions are summarized by the Six Sources and Seven Principles of Unitarian Universalism, documents recognized by all congregations who choose to be a part of the Unitarian Universalist Association. These documents are 'living', meaning always open for revisiting and reworking. Unitarian Universalist (U.U.) congregations include many atheists, agnostics, and theists within their membership—and there are U.U. churches, fellowships, congregations, and societies around the world. The roots of Unitarian Universalism lie in liberal Christianity, specifically unitarianism and universalism. Unitarian Universalists state that from these traditions comes a deep regard for intellectual freedom and inclusive love. Congregations and members seek inspiration and derive insight from all major world religions.
Unitarianism is a Christian theological movement named for its belief that the God in Christianity is one entity, as opposed to the Trinity which in most other branches of Christianity defines God as one being in three persons: the Father, Son, and Holy Spirit. Unitarian Christians, therefore, believe that Jesus was inspired by God in his moral teachings, and he is a savior, but he was not a deity or God incarnate. As is typical of dissenters, Unitarianism does not constitute one single Christian denomination, but rather refers to a collection of both existing and extinct Christian groups, whether historically related to each other or not, which share a common theological concept of the oneness nature of God. Unitarian communities have developed in Britain, South Africa, Central Europe, India, Canada, the United States, Jamaica, Nigeria, and Japan.
