A miracle is
called supernatural because the effect is beyond the productive power of nature and implies supernatural agency.
Thus St. Thomas Aquinas teaches: "Those
effects are rightly to be termed miracles
which are wrought by
Divine power apart
from the order usually observed in
nature"
Contra Gentiles,
III, cii
"and they are apart from the natural order
because they are "beyond the order or
laws of the whole created nature"
Sacra Theologica I:102:4
In ordinary language: that which is beyond the present knowledge and power of the medical or physical sciences.
