I have not read anything by Bardon, so Ileave that part of your question untouched.
I would like to mention that nearly everything of any kind that I have seen coming from self-professed Satanist, Luciferians, LHP, sect (without exceptions) belies serious ignorance on just about any theological or occult subject brought to the table.
Granted, there are fine scholars among them, and granted that a great deal of what comes from all these organizations has some validity. Barring the "Joy of Satan" nonsense and people who just want to adapt medeival grimoires to "dark" themes in spell-casting, most of the organized Satanic sects have a coherent and applicable philosophy to offer their adherents.
I actually know one Church of Satan priest who said Carl Jung (see "Christ Consciousness and Mandala Meditation") had more to offer for Satanic philosophy than Aleister Crowley.
If you like cognac and old jazz, guns, mobsters, and freaky humor, LaVey's crowd is for you. If you like werewolves, secrets of the nazi overlords, and possibly small children, the Setians have a mailing address and you should contact them. For most other forms of unusual interests, there is a Satanic organization waiting to accept you. But for magic and the occult? Not the slightest chance.
This is not to say that they don't know anything at all, that they cannot cast spells and beseech favors from wicked devils, but simply that what these sects promote is by and large totally lacking in-depth study of any occult discipline. they tend to grab a few of the names and sigils, add whatever else fits their aesthetic sense, and tell you how majestically powerful their black arts are.
"You don't need to know any of that occult nonsense" they will say, and perhaps rightly so, but the vast majority of the adherents do not know the slightest bit of what it is they are dismissing, whle still promoting bits and pieces of it here and there as the great powerful rituals of evil. I don't mean to say that they are all wrong or that they are incompetent, but if you look for magic and the occult among Satanists you will find them to be ignorant on almost all accounts.
