I need to explain myself about that.
I will first say that I had no expectations about this show respecting Christians. But I did unfortunately have expectations that they wouldn't have the witches using black magic that was given to them by the Prince of Darkness either. Boy was I wrong. The moment I saw those photos of the Horned God at Sabrina's birthday, I knew this show was gonna be bad. When I saw her smiling at that guy with this mischievous look, like she was looking at an old friend, that told me everything I wanted to know about the show; that it was gonna glorify Satan and everything he stood for, and I was right, as it turns out.
The original Sabrina tv show in the 90s didn't mention religion very much, save as lightly poking fun at it. Only two episodes make any reference to religion of any kind, and in one of them, Sabrina was just being playful about Christianity. I didn't find what she said insulting at all, and I got that she and her family wouldn't be Christians, but they don't appear to worship Satan either. In fact, her aunts showed more of an inclination towards ancient Greek/Roman paganism than anything else!
