Christian tradition often depicts Satan as a fallen angel who rebelled against God and was cast out of Heaven.

Christianity portrays Satan as a once-high angel, sometimes called Lucifer ('Light Bearer'), who led a rebellion against God. This narrative is not explicitly detailed in the Bible but is derived from interpretations of passages like Isaiah 14 and Ezekiel 28, alongside New Testament references such as Luke 10:18. The imagery of Satan as a proud angel cast down from Heaven became central to Christian theology and art, symbolizing pride, disobedience, and the origin of evil. This figure appears in countless works of literature and art, embodying the ultimate adversary of God and man.
