The Differences Between Satanism and Christianity

I'm not advocating for imposing a certain religion upon society. I don't think most theonomists are. However, we would all recognize that there's a vast difference between Satanism and Christianity. And so we can't say that just because the civil magistrate isn't promoting reform Baptist theology and society, that they somehow get to act as if they're neutral. There's one God, the triune God, and when he does- Who's servant they are?
