Is Lucifer the same as Satan?
The name Lucifer appears once in the KJV, in Isaiah 14:12, within a taunt against the king of Babylon. Since the early church many Christians have also read the passage as describing Satan's fall, so Lucifer became a common name for the devil, though the Bible never directly calls Satan "Lucifer."
The name Lucifer occurs only once in the King James Bible: "How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!" (Isaiah 14:12). The Hebrew word, helel, means "shining one" or "day star," most likely the morning star we know as the planet Venus. "Lucifer," Latin for "light-bearer," comes from the Latin Vulgate's rendering of that word, and the KJV translators kept it. In its immediate setting, the passage is a "proverb against the king of Babylon" (Isaiah 14:4), mocking a proud ruler who said, "I will ascend into heaven" and "I will be like the most High" (Isaiah 14:13-14), only to be "brought down to hell, to the sides of the pit" (Isaiah 14:15). Many early Christian writers, including Tertullian and Origen, saw in this language something larger than a human king, reading it as a picture of Satan's original pride and fall. They often linked it with Ezekiel 28, a lament over the king of Tyre that speaks of one who was "in Eden the garden of God" and "the anointed cherub" until "iniquity was found in thee" (Ezekiel 28:13-15), and with Jesus' words, "I beheld Satan as lightning fall from heaven" (Luke 10:18). Over time Lucifer became a popular name for the devil, used famously in Milton's Paradise Lost. Today some interpreters read Isaiah 14 strictly as a taunt against Babylon's king, while many others see a double reference, describing the king while also pointing to the spiritual power behind him. Either way, the New Testament's own names for this enemy are Satan, the devil, and "that old serpent" (Revelation 12:9). Interestingly, the image of the morning star is also applied to Christ, who calls himself "the bright and morning star" (Revelation 22:16).
