How important is the Virgin Mary to Christians outside of Roman Catholicism?

i'm a seventh day adventist christian and my church believes that she is important, but not important like a god! the roman catholics worship her like she is one and i wonder why! she's jesus's mother- sure, but she's not a goddess! she was a normal human being and didnt ascend to heaven or anything. what if jesus's mother was a prostitute? or something worse? would they worship her then? its obvious god blessed her, but JESUS should be the focus of the christian church. that's why we're called CHRISTians, not MARYians.
