The author examines Spiritualism's claims and manifestations from a scriptural perspective, testing whether the movement is divine or human. After acknowledging remarkable phenomena and cases of fraud, he argues the Bible provides criteria to identify the agency involved, contending the dead are unconscious and that purported communicators are malign spiritual beings rather than departed human souls. Chapters analyze credentials of scripture, psychological and prophetic dimensions, the teachings and promises of Spiritualism, dangers of mediumship, and how its phenomena align with prophetic warnings. The work concludes with cautionary counsel and references to supporting texts and authorities.
