This is not a stupid question, as Zola already stated.
Well, every Gentile can access this religion, if they wish to. The dedication ritual is the first step into becoming a Spiritual Satanist. However, that's not all there is to it. This religion is unlike no other on the planet. You're not a Zevism only because of your newfound beliefs and the fact your performed the dedication ritual. Not at all. You got to be strong and put in the effort. What does that means? It means that if you want to be regarded a Satanist, you have to:
• Meditate consistently everyday and do yoga. This is the core of Satanism, working to empower yourself and reach new heights with time.• Participate in the war effort by doing Rituals. We are at war and everyone must do its part to secure the best future possible. How much you do is your choice, but the minimum required is performing once per day every Ritual in the daily schedule.
That's all there is to it. If you aren't doing this stuff, you're just a dabbler and not a true Satanist. This religion is for the strong and in time weaklings will either grow and become strong or wither and perish, as per nature's laws (e.g. survival of the fittest).
I hope this was helpful.
