"Preceptor"
Pseudonym of one of the spirit controls of William Stainton Moses, who later claimed to be the biblical Elijah. "Imperator" (another control) frequently referred to "Preceptor" as his "Great Master" and director of the movement to uplift humanity through the teachings they delivered to Moses under the leadership of Jesus. Reportedly "Preceptor's" first signed communication was May 27, 1876. He was seen clairvoyantly by Moses as a communications link between himself and Malachi in the chain of spirit influence from Melchizedek to Jesus.
