Unitarian Universalist thinkers have long recognized the need to bring belief and action together, and encourage their members to go into the larger world and improve it. Because of this importance of action, Unitarian Universalists have long been involved in social, economic, and environmental justice movements, both through organizations created by Unitarian Universalists and through local, regional, national, and international grassroots organizing. Many Unitarian Universalists see this work as inseparable from their Unitarian Universalist faith, and see their participation in justice movements as a deeply important part of their religious faith. Historically, Unitarian Univeralist's predecessor denominations, Unitarianism and Universalism saw members involved in abolitionism, women's suffrage, pacifism, temperance, and prison reform. Today, Unitarian Universalists are deeply involved in causes such as racial justice and the Black Lives Matter movement, LGBT movements, feminism and women's rights, immigration justice, reproductive rights, climate justice, and economic inequality.

Children's and youth's religious education classes teach about the divinity of the world and the sanctity of world religions. One of its more popular curricula, Neighboring Faiths (formerly Church Across the Street), takes middle and high school participants to visit the places of worship of many faith traditions including a Hindu temple, a Reform or Orthodox synagogue, and a Catholic church. There is great variety among Unitarian Universalist congregations, with some favoring particular religious beliefs or forms of worship over others, with many more home to an eclectic mix of beliefs. Regardless of their orientation, most congregations are fairly open to differing beliefs, though not always with various faith traditions represented to the same degree. Diversity of congregations There is a wide variety in how congregations conceive of themselves, calling themselves "churches", "societies", "fellowships", "congregations", or eschew the use of any particular descriptor (e.g. "Unitarian Universalists of San Mateo"). Many use the name "Unitarian Universalist", (and a few "Universalist Unitarian"), having gradually adopted
