Unitarian Universalism is a liberal religion characterized by a "free and responsible search for truth and meaning". The Unitarian Universalist (UU) Church does not have a creed. Instead UUs are unified by their shared search for spiritual growth. As such, UU congregations include many agnostics, theists, and atheists among their membership. The roots of UU are in liberal Christianity, specifically Unitarianism and Universalism. Unitarian Universalists state that from these traditions comes a deep regard for intellectual freedom and inclusive love, so that congregations and members seek inspiration and derive insight from all major world religions.
