The Shakers were a charismatic and heretical group of Christianity in early America, 18th-19th centuries. This site reprints with favor some of their early writings. Since not all the writings are present, i wonder if the embarassing stuff has been left out. According to Answers.com there is one community still active in Massachusetts. The Answers.com entry includes this,
One of the fundamental doctrines of the society was belief in the dual nature of the Deity. The male principle was incarnated in Jesus; the female principle, in Mother Ann. Other tenets were celibacy, open confession of sins, communal ownership of possessions in the advanced groups, separation from the world, pacifism, equality of the sexes, and consecrated work. Singing, dancing, and marching characterized phases of Shaker worship. The community was organized into groups, called families, of between 30 and 90 individuals. The believers donated their services and possessions but were always free to leave. Shaker furniture and handcrafts are noted for their fine design and crafting.
