Declaration of Principles

As an informal movement, spiritualism does not have a defined set of rules, but various spiritualist organizations within the United States have adopted variations on some or all of a "Declaration of Principles" developed between 1899 and 1944. In October 1899, a six article "Declaration of Principles" was adopted by the National Spiritualist Association (NSA) at a convention in Chicago, Illinois. An additional two principles were added by the NSA in October 1909, at a convention in Rochester, New York. Then, in October 1944, a ninth principle was adopted by the National Spiritualist Association of Churches, at a convention in St. Louis, Missouri.

In the UK, the main organization representing spiritualism is the Spiritualists' National Union (SNU), whose teachings are based on the Seven Principles.
