Many Christian writers have expressed their doubts about the excessive usage
of the
word 'supernatural' for reasons such as this. CS Lewis and James Houston
come to mind.
Christian doctrine emphasizes the simultaneous and equally-important
relationships of transcendence and immanence. Transcendence: God is not
nature, not natural, not physical, not finite, not temporal, not mortal, not
changeable. Immanence: God is everywhere, at all times past present and
future, inescapable and pervasive even in sheol.
The confusion may go back to what Boyle called the "vulgar received notion
of nature" that he traced to ancient Greek and Roman (i.e. pagan)
conceptions (Greek physis = nature). Ted Davis edited a book of Boyle's on
this subject recently that offers a critique that has the distinction of
coming from a scientist from the pre-"Enlightenment" era, without the burden
of presuppositions of that era.
