“Devil Worship” and “Church of/LaVeyan Satanistm” are 2 different things.
One of the first sacraments satanism is the act of lying. This causes the devil and his followers to pretend to be something other than what they are.
An example of this deceptiveness is when any given “church of satan” pretends to be “not devil worship.”
But when lying is your first principle, the price you eventually pay is your credibility.
