Organization could help non-Spiritualists distinguish genuine mediumship from the rapidly proliferating varieties of fraudulent mediumship, increase communication among Spiritualists, prevent the legal prosecution of spirit mediums under fortune telling and medical licensing laws, and counterattacks by "orthodox" ministers in the press.
