Is King Diamond both a LaVeyan Satanist and a Theistic Satanist?

Its basically the same. Quotes from famous musician and High ranking Church of Satan member and very close friend to Anton LaVey - King Diamond "Satanism is about the Powers of the Unknown. I have had hundreds of strange supernatural experiences with the occult, the other side, the beyond, whatever you want to call it that proves there is a spiritual world that can cross over into our world. Satanism is a life philosophy so within it you can have your own religion, any religion you want. Or take from various religions or your own whatever makes you happy. I have my own beliefs and Religiously Satan on a spiritual level stands for the Powers of Darkness, the Powers of the Unknown which are always all around us at all times. This is the best way to talk about these Spirits and Powers. Not a god or a devil as both of them are christian god's and that has nothing to do with Satanism. Of course there are different types of satanism. And I never wear gold as that is not healthy for you!

Must need something bad and use that during ritual then you might be able to get help from these powers I believe are all around us. But that is only if they like you. I do not believe in the two christians beings god or the Devil, I believe in the Powers of the Unknown, Powers of Darkness, The Powers of the Occult what ever name you want to use. . I have done Satanic Rituals and have seen and heard spirits.

Some people like to call "Them" God or the Devil or whatever, but I do not believe there is all one good and one all bad power. I believe there are many, many different Spirits and Powers that exist and that they are not good or evil, like humans they have both inside of them and I always treat them with the highest amount of respect and feel that respect returned by Them. It is massive mutual respect. Not Power, but Powers, Big difference. I believe we are one and the same me and these Unknown Forces. You really have to respect them for the incredible power they have. I believe they come to those who they feel can handle it and who will be faithful believers." In the song "Welcome Princess of Hell" you hear me singing to these spirits and powers and they sing back to me. They came to me to let me know they are here for me on my journey and that they are behind me and that they wish me good luck so I see them as my protectors almost like guardian angels. We all live several lives so that our powers/souls can grow in order to reach a higher plane and join with something greater. Our powers live in a human shell several times that will enable us to go on to a new life form a higher plane of being or join one day with a larger greater force. But 99 percent of the population live by the Satanic Philosophy whether they know it or not. As Anton LaVey even told me that Satanism is simply a life philosophy and NOT a religion. Satanism is basically Humanism. Satanism is based on logic and things that are proven which is why it could never be a religion as religion is based on things that cannot be proven.

And that’s why I say that these powers of darkness are always welcome in my home. It’s as if the powers of the unknown came and said ‘Hey, we will stay with you and help you.’ That’s what I feel.”

Personally I do not use electrical lighting at home and on my Satanic Altar or in the studio when I record vocals, only black candles as electrical lighting drives away the spirits and I love having them near me. People who see Satanism from the Christian view point are not treating these powers with respect and that is very dangerous. I once actually summoned a spirit in order to prove they are real to a girl who doubted and Satan came. My wife will not look in our mirror in fear something will come out.

In Satanism you are your own God. LaVey felt and I agree that we are all individuals born with different needs and views and so he felt everyone should make up their own mind about what to believe in spiritually if anything at all which is why he left a huge void in the Satanic Bible when it came to spirituality or any kind of religious beliefs and so within the Satanic Philosophy a person can still be a Christian if that fulfills their spiritual needs. Satan also means the Opposite, Inverted, Reversed which is why we wear the Satanic crosses and pentagrams. Satan means the opposite of religion. Satanism is living out your feelings and instincts without feeling it is a sin, enjoy yourself while you are here now while you can and have your own individual beliefs. One thing I consider almost mandatory though is believing there are powers around us. And you can use these powers to help yourself or those you care about. Or throw these powers at people in a negative way. I am not religious at all but you can say I am spiritual due to my experiences and beliefs. The Satanic bible is not really a bible because a bible is for religion so it should be called a book of philosophy instead. Do what thou wilt shall be the whole of the law.

When people see the word ‘Satan’ they see only negative. Satan is not only bad, to me. It represents both sides of everything. I don’t believe in the Christian devil.

“Christianity has both God and the devil. I believe there is neither of these two. I believe in the powers of the unknown, which I have experienced many times. I know that rituals work. I don’t do them often because you can easily misuse them. They will get back at you if you don’t respect them. Rituals can channel the forces that surround us all the time but I respect the powers and will not abuse them in any way. The Satanic Bible is 70 percent Philosophy and 30 percent magic. Satan is the power of the universe. Satan to me is the Powers of Darkness, not a man with horns. Some people think Satanism is what the Christian church portrays it to be. If you are as bad and as evil as you can be and you think that’s Satanism then you have become part of the Christian religion. That is Christian Satanism which is not what I am about at all.

LaVeyan Satanist. He's mentioned it in interviews.

the stage character is a theistic satanist, the person just wants to freak out the squares.
