Although old tribal beliefs in witch doctors are not so deeply buried in people's memories, and although there had been indigenous Christians in Nigeria since the 19th century, it is American and Scottish Pentecostal and evangelical missionaries of the past 50 years who have shaped these fanatical beliefs. Evil spirits, satanic possessions and miracles can be found aplenty in the Bible, references to killing witches turn up in Exodus, Deuteronomy and Galatians, and literal interpretation of scriptures is a popular crowd-pleaser.
