Lucifer is the figure traditionally identified in Christianity as the devil, often described as a fallen angel who was originally a cherub.
The name Lucifer comes from the Latin word for “light-bearer” or “morning star.” In Isaiah 14, the underlying image refers to the morning star and is presented in the context of the king of Babylon. Later Christian interpretation connected that passage with Satan’s fall from heaven, helping establish Lucifer as the devil’s pre-fall name.
The cherub detail is associated especially with readings of Ezekiel 28, which describes a majestic figure in Eden. These passages do not present a single straightforward biography of Lucifer, but later theology combined them with New Testament references to Satan’s fall.
Lucifer is therefore a traditional theological identification rather than a universally agreed biblical name for Satan. Beelzebub and Belial are separate names associated with demonic figures, while Abaddon is a different apocalyptic figure.
