Questions on Spiritism and Occultism
A 1927 pamphlet from The Leyden's Home Missionary Movement discusses spiritism and occult practices, citing Biblical verses on witchcraft, familiar spirits, and communication with the dead. It probes why the dead cannot communicate with the living, lists fallen angels and demons, and references various scriptures as sources for Christian opposition to occult practices.
