Necromancer – A person who uses witchcraft or sorcery to foretell the future by communicating with the dead.
God used this word once in Scripture, to Israel in their Masoretic Text Old Testament (Deuteronomy 18:11).
Today, in the Dispensation of Grace, according to Scripture, there is no communication with the dead, Divine Intervention, Satanic Intervention, or etc. These things did occur prior to the resurrection of Christ. But with the introduction of the Gospel of Grace these things are now just ignorant superstitions purported by Christianity.
