The core idea of Theistic Satanism is the belief in Satan as an entity. Spiritual Satanism is an individualistic belief system around the idea of Satan as an entity, a personal relationship between the Satanist and Satan. Religious Satanism is where an individual has chosen to adopt structured predefined ritual and ideology (dogma) as part of a shared group-minded activity around the idea of Satan as an entity, commonly described as devil worship.
The individual Satanist chooses liberty over slavery regardless of their form of Satanism
Religious Satanism in all its forms is problematic in that it results in the individual becoming enslaved to dogma, entity or group. If it is accepted that the ideal of the individual Satanist is “manifestation of personal will to become their own god in their own life,” then nothing can become a master other than self in their own life, thus all enslaving aspects must be avoided. Pursuit of the individualistic form that is Spiritual Satanism places the entity of Satan in the form of a liberating guide at the right-hand of the individual, rather than as an enslaving entity that the individual has chosen to worship as a slave. At all times the Satanist is master and never slave, thus Satan becomes a guide rather than master, where the individual Satanist is the primary authority in their own lives, and Satan is placed as a type of guiding figure rather than a master to be worshiped.
In my opinion the individual is no better off if they are enslaving themselves to Satan than they were if they had previously been worshiping Jesus. It is perfectly acceptable in my opinion to believe in Satan as an entity, as longs as the individual remains as central authority in their own lives i.e. rejecting all slavish notions.
Satan can take many names and appearances, but the meaning the Satanist gives to Satan is important
Satan can take the form of many names and appearances, all which is down to the individual preference of the Satanist, for instance the belief in Satan as the entity called Cthulhu in the Lovecraft books. The form that Satan takes is not so important as the meaning that the individual Satanist gives to Satan, which in my opinion should promote values of liberation, empowerment and personal development for the individual Satanist.
