The authority to cast out demons and to free the world from their dark threat, for the sake of the one true God, is the same authority that rules out any magical understanding of healing through attempts to manipulate these mysterious powers. Magical healing is always tied to the art of turning the evil onto someone else and setting the “demons” against him. God’s dominion, God’s Kingdom, means precisely the disempowerment of these forces by the intervention of the one God, who is good, who is the Good itself.
