Luciferianism is a belief system that venerates the essential characteristics that are affixed to Lucifer. The tradition usually reveres Lucifer, not as the Devil, but as a rescuer or guiding spirit or even the true god as opposed to Jehovah.
Luciferianism is identified by some people as an auxiliary of Satanism, due to the popular identification of Lucifer with Satan. Some Luciferians accept this identification or consider Lucifer the light bearer aspect of Satan. Others reject it, arguing that Lucifer is a more positive ideal than Satan.
