Almost every messianic movement in the world came into being as a result of hallucinatory visions of a prophet. One point must be emphasized about the prophet of a messianic movement: He is not a schizophrenic, as was so long assumed. A schizophrenic with religious paranoia will state that he is God, Jesus, the Great Spirit, or some other supernatural being. The prophet, on the other hand, never states that he is supernatural—only that he has been in contact with supernatural powers. (Of course, after his death, his disciples tend to deify him or at least give him saintly status.)
