Seperating the "Magical" from the "Supernatural"

[Florian]

How might one go about making a clear thematic distinction between "magical" creatures and effects and "supernatural" creatures and effects?

I know the line often gets muddled mechanics-wise, what with clerical magics, spiritualists, and abilities that are "extraordinary" rather than strictly magical. What I'm trying to do is make a clear division between the inherently magical and the inherently spiritual or supernatural. Has anyone else had experience in making this distinction? If so, how did you show it, both thematically and mechanically?

It´s a stance on how reality works. It´s like saying that "we" are bound by the "natural" rules that encompass, say, 1/3 of it, and that works finde, reality and physics are stable, but there are also the other 2/3 that can do things that are way beyond our "regular third" and are still part of reality. Magic is what bridges the gap here.
