Satan is a real, existing being, working among people, In the Holy Scripture he appears as early as the Book of Genesis, as the serpent. It is he who persuades the first people to be disobedient to God and thus leads them to their fall. The devil is a cunning tempter who leads away from obedience to God. From then on his work is identified with the spreading of sin, suffering and death. In the book of Job, Satan’s impudence, his power over the physical world and his perversity are shown. The tempting of Jesus Christ depicts the evil spirit as a usurper. It is visible in biblical scenes of exorcism. The devil, tempting through greed, induces Judas to denounce Jesus to the Pharisees.
