What is the relationship between ‘The Devil and humankind’? In the 16th and 17th centuries, Satan's kingdom is described as the demonic inversion of goodness. He is an anti-God and his son is Antichrist, whose appearance will presage the Last Judgement. A central theme of Jesus' ministry in the New Testament is exorcism — the expulsion of demons. Christians struggle against demonic temptation and suffer punishment if they fail. Sin is the Devil within. In the pre-modern world, the Devil can take control of a person's body. From the 18th century onwards, scientific naturalism and an insulated concept of self gradually diminish belief in the power of demons.
