Lucifer vs. Satan

Lucifer vs. Satan: What's the difference?

Both Lucifer and Satan are names for the devil, the personification of evil. Satan is seen as a fallen angel and the adversary of humanity and God in Christianity and Islam, but as an entity subservient to God in Judaism. Lucifer is a mythological figure whose name was later adopted into Christianity to refer to Satan. The connection between the two figures was popularized by John Milton’s epic poem Paradise Lost.
