Revelations of John<quoted text>
Satan as an entity is only in Job, Jesus' desert vision and the hallucinations of John of Patmos.
The Satan of modern Christianity is based on the fictional works Dante and Milton, not the Bible.
Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. 8 But he was not strong enough, and they lost their place in heaven. 9 The great dragon was hurled downthat ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him.
The Satan is the Gods plaything of destruction.
