Does the Bible directly oppose witchcraft? Does it make any difference if it is white or black?
The Bible is unequivocal about prohibiting witchcraft in any and all forms. For example, Leviticus 19:26-28 makes evident that witchcraft was prohibited for God’s people even in Old Testament times. Furthermore, in 1 Samuel 28 we have the story of how King Saul expelled all mediums and wizards from the Holy Land and then himself consulted a medium, which the narrator of the story makes clear is a very grave sin. In the New Testament, Paul lists sorcery as one of the sins that can keep a person out of the kingdom of God (Galatians 5:20).
