End of Days : How was she so rich?

How was Christine so rich? Was this ever explained? She also came across as a very sheltered naive spoiled rich girl..I know we are supposed to root for her but she just annoyed me

I assumed that the wealth came from her parents. It was mentioned that the mother died and the father married the live in nurse, then the father died. Obviously that part was all according to plan so the 'nurse' could control Christine.

It may have been wealth from the Satanists since they alresdy knew Christine was the cosen one.
