This may be a good way of working with the debates people have over how to define a miracle. My guess is that most of us probably do agree, but as a friend said in the comments of my original, it can be about semantics.
I do believe we have to be careful about relegating all miracles to only what God can obviously do, though, because then we can fall into the idea of the "God of the gaps," where God only does what science cannot explain. And that gap gets smaller and smaller everyday.
I fully believe God works through science and in ways that we can "explain away" fairly easily. And that's the beauty of his work.
