Ernst Haeckel and Natural-Scientific Materialism , V.I. Lenin
The word "science" goes back to ancient times. It has always been that branch of philosophy which deals with the natural material world, not the supernatural. Supernatural comes under metaphysics = "beyond physics".
I know, ECO, you desperately want to turn this into an argument of "Science versus Christianity." Then you could zero your rhetorical weapons and happily fire for effect, right?
But I'll remind you that the vast majority of Christians belong to denominations which have long since accepted the school of thought called "theistic evolution," which is also what I believe.
