You are in Beware the Wolves -> List of False Teachings
Many Christians mistakenly believe that “Lucifer” is the name of the devil (Satan). They believe this simply because they hear others repeating it. The secular world also loves to repeat this, for they do not know any better. However, this is a false interpretation of Isaiah 14:12 (KJV translation). The context of the verse mentioning “Lucifer” is speaking of a specific man, a king/ruler, not Satan.
Various names are given to Satan, including: “the Devil” (Greek diabolos), “serpent/snake”, “Abaddon,” “Beelzebub,” and “Belial.” His name means adversary and deceiver. He is also described as “a liar and the father of lies,” “a murderer from the beginning,” and that “there is no truth in him” (John 8:44). He is your “accuser” before God (Revelation 12:1, Job 1), “the prince of the power of the air [this fallen world]” (Ephesians 2:1-2), and “the ruler of this world” (John 12:31). Note, however, that he is not called “Lucifer.
You might wonder why I am spending time addressing such an unimportant false teaching, which is obviously not a matter of salvation, since we are told not to “wrangle about words.”[1] The reason is to teach you that you need to watch for a pattern, which is: Where you find one false teaching, you will almost always find others lurking nearby from the same group, sect, or cult. False teachings, like “wolves,” often travel in packs. So, when you hear the name “Lucifer” being bandied about as the name for Satan, you know that you need to be on the alert for other false teachings as well! [2]
