Deuteronomy, Chapter 18, Verses 10 and 11: There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch. Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.
Ephesians, Chapter 5, Verse 11: And have no fellowship with the unfruitful works of darkness, but rather reprove them.
Translation: Don't be a Satan-worshiping necromancer. Don't have any connections to them.
This is pure evil. This is nothing more than an evil, Satanic plot to twist people's minds to thinking that necromancy is nothing more than an innocent game.
