Satan and witchcraft (again?)

Rating: Null/10 (22 May 2000)

I have a question about Sleepy Hollow (1999). I had just seen it for the first time and felt there was at least one error.
There were two young girls that saw the living "headless horseman" - one ran away, and the other saw the beheading. The girl that witnessed the beheading said that she "sold her soul to satan that moment."
It is well pounded in my head that witchcraft has nothing to do with satan, but in the movie, satan and witchcraft were paired up once more.
I also found the clash between science and religion (Christianity) and paganism and religion interesting. I.e., the comment of "The only book you need to know is..." (WHAM) - the Holy Bible plopped in front of the constable.
Good movie, nonetheless.
