The defining theology of Universalism is universal salvation; Universalists believe that the God of love would not create a person knowing that that person would be destined for eternal damnation. They concluded that all people must be destined for salvation.
American Universalism developed from the influence of various Pietist and Anabaptist movements in Europe, including Quakers, Moravians, Methodists, Lutherans, Schwenkfelders, Schwarzenau Brethren, and others. Pietists emphasized individual piety and zeal and, following Zinzendorf, as a "religion of the heart." Early followers were most often German in ancestry. The majority of the early American Universalists lived in the Mid-Atlantic colonies, though Rhode Island also had a fair amount of followers.
The Universalist Church of America involved itself in several social causes, generally with a politically liberal bent.
Universalists, along with various other denominations, vigorously opposed slavery as immoral. They also favored postbellum legislation such as the Fifteenth Amendment and the Freedman's Act to enfranchise all American citizens.
Like many American religions, Universalism has generally been amenable to church-state separation. In New England, Baptists, Universalists, and Quakers provided some of the loudest voices calling for disestablishment of the government sponsored churches of the standing order.
On June 25, 1863, Olympia Brown became one of the first women in the United States to receive ordination in a national denomination, Antoinette Brown having been the first when she was ordained by the Congregational Churches in 1853.
