When you make a rule public, you can either be a goody two shoes, or be above those who follow the rules by finding loopholes or manipulating it.
For example, in Satanic Lesser Magick, one can reasonably predict the desired stimulus for someone else based on the rules that he/she follows. e.g., instead of outright revenge for an offense committed by say, a Christian, one can instead very publicly forgive him, and in the process gain credit and respect for yourself, because you are so "Christ-like".
Or you can suppress certain behaviors from others by using their rules against them. e.g., a lot of people won't dare to say, sleep with your wife, lest they are caught and publicly humiliated in front of their friends who share the same belief system. So you can reasonable expect a "good Christian" to not do so, with zero investment from yourself in ensuring the outcome.
We should be thanking Christians everyday. Their doctrine does a lot of favors for us. Plus, we Satanists are not bound by the same rules (or any rules really), so we can be more effective in achieving our goals by manipulating their rules against them.
Imagine you are a general of an army. You can't be called a great general if you have no walls to siege, and no castles to conquer. The existence of your "enemies" is a boon to you, for through crushing them, you gain glory and fame.
If everyone was an atheist, or if everyone was a rational thinking scientist, we'd have NOTHING to base our predictions about the outcome of certain stimuli in Lesser Magic on. Because every single person will have wildly different worldviews. When that happens, Satanic Lesser Magic is done for. No more twisting people around your fingers, because you won't know how to twist them.

Fun exercise: Knowing that a person has faith in fiction is knowledge of a weakness possessed by said person. How can this be usefully applied by the Satanic operative?

"Satan has been the best friend the church has ever had, as he has kept it in business all these years". I don't understand how somebody calls himself a " Laveyan Satanist" and contradicts himself by saying that "satanism needs Christianity, and has to give thanks for christianism". I personally know that Christianity is full of money suckers, and the only good thing they have for me is their holy scriptures to clean up my pupu , just holy paper to go to the wash room to wipe out my holy a a a a.
Way to present rational thought brah. Saying the Holy Bible is only good for wiping your ass may be funny, but it presents no real thought of value.
