Spiritualism is the Science, Philosophy, and Religion of continuous life, based upon the demonstrated fact of communication, by means of mediumship, with those who live in the Spirit World.
Spiritualism has been called a religion of conviction, not conversion.
Many discovering Spiritualism feel they have come home. Students learn the Science, Philosophy, and Religion of Modern Spiritualism. Spiritualism proves the continuity of life—that life continues after so-called death. Through its religion, Spiritualism follows Natural Law, the law of God (Infinite Intelligence).

Definitions
A Spiritualist is one who believes, as the basis of his or her religion, in the communication between this and the Spirit World by means of mediumship and who endeavors to mold his or her character and conduct in accordance with the highest teachings derived from such communication. (1914, Rev. 1938) Learn about Joining a Spiritualist Church
A Medium is one whose organism is sensitive to vibrations from the spirit world and through whose instrumentality, intelligences in that world are able to convey messages and produce the phenomena of Spiritualism. (1914)
“The office of mediumship is to bless humanity, to enable the race to overcome conditions of matter sufficiently to make such the servant rather than the master of intelligent beings, to enable it to guide (through intuition) the individual for their own and others good.”
Mary T. Longley from “Teachings and Illustrations As They Emanate From The Spirit World.”
