In Christianity, Satan is often seen as the leader of the fallen angels. The New Testament mentions Satan 36 times in 33 verses, and the Book of Revelation tells of "that ancient serpent, who is called the devil and Satan, the deceiver of the whole world '', being thrown down to the Earth together with his angels. In Luke 10: 18, Jesus says: "I saw Satan fall like lightning from heaven. '' While the New Testament thus mentions Satan falling from Heaven, it never says that he was an angel, only that he masquerades as one in 2 Corinthians 11: 14. The concept of fallen angels is not foreign to the New Testament, though; both 2 Peter 2: 4 and Jude 1: 6 refer to angels who have sinned against God and await punishment on Judgement Day.
