If a miracle can be explained then it would fall out of the realm of the supernatural to the natural.
I don’t think “supernatural” or “natural” are the categories we should be using. We tend to define a “natural” thing as something that can be explained through natural causes and a “supernatural” thing as something that cannot be explained through natural causes…but
that boundary is only “firm” until the next natural process is discovered.
Plus, and more importantly, can we legitimately separate God from even the natural processes we have documented? For example, if an apple falls to the ground on account of gravity, isn’t God the one “powering” gravity in the first place? My understanding of Christian ontology is that only God “really” exists, whereas everything else exists contigently upon God’s will for it to exist. So the earth’s continued existence is dependent upon the will of God for it to continue existing. There is, therefore, no such thing as a “natural” process in the sense that this process can continue functioning as normal apart from the direct involvement of God’s creative and sustaining energies.
In short, I think that instead of “natural” and “supernatural” processes, perhaps better categories would be “explained” and “unexplained”, or, perhaps better yet, “explainable” and “unexplainable”. But science works on the fundamental principle that
everything can be explained. Not knowing an explanation, then, is not the same thing as saying no explanation can ever be found. And that’s where I think the conflict arises. Jesus turns water into wine, and the non-scientist says, “It’s a miracle!” while the scientist starts thinking up hypotheses and ways to test them, always
assuming that an explanation of the miracle is a goal that
can be reached somehow. The scientist
has to make this assumption up front because if the scientist believes that something can’t be explained, he/she isn’t about to spend potentially years of his/her life studying unexplainable phenomenon.
Now, if this is the case, we are certainly in the wrong if we condemn scientists for making an assumption that they
have to make if they want to do science! Likewise, I think that if we make a distinction between “natural” and “supernatural” as if God’s involvement were the deciding factor between the two, because God is involved in absolutely everything that occurs or exists in creation!
I can only hope this little bit of rambling makes sense.
