Spiritism, spiritualism, and the occult often get mixed up. In fact, spiritism and spiritualism are often used interchangeably, with the most notable difference being that spiritists believe in reincarnation, while not all spiritualists do. Both spiritists and spiritualists believe that disembodied spirits can communicate and carry on relationships with incarnate human beings. Spiritists, though, are empowered to make their own connections with God apart from the work of priests or others invested with spiritual authority. From a Christian perspective, spiritists have made a science, with its own philosophy, out of wizardry and the occult. Occult practices, in general, are regarded by many to be a legitimate aspect of mystical spiritual experience; indeed, modern spiritism is regarded to have emerged from the ground of Swedenbor-gian practices. Psychotherapists do not operate primarily as theologians, evangelists, or apologists for any given spiritual or religious group.
