A person lights a match in the middle of a train carriage. Two persons observe this from either side of the carriage; they are separated by the same distance. The train travels at 80 km/h. Light will still hit at the exact same time on both persons. Even though the train moves, the speed of light is not affected by movement or direction. This proves that although light are waves, it does not move through a medium, like sound waves move through air or water. Light travels the same speed regardless the direction.
Luciferianism is a very small and individualistic path. As a rule of thumb Luciferians agree and believe that morality is a natural occurrence. Everyone might have diverse beliefs regarding the afterlife, but generally all Luciferians agree about some sort of enlightenment. Whatever comes after, nobody could honestly claim to know for certain.
As for belief in "supernatural beings", some Luciferians believe in angelic and demonic beings, sometimes multiple gods whilst others believe in a more deistic, pantheistic, panentheistic god. The belief in God does not affect Luciferianism, because whether one exists or not, one still must delve deep into oneself to connect. So, the outcome still remains in seeking self-enlightenment.
Concerning religion, there is none, as spirituality and religion cannot coexist. Luciferianism is a path, a way of life. The magick is an intensely deep, personal, natural and psychological thing. We are dealing with our own minds and the strength that comes from within.
