"I believe in science, not Christianity."
This statement is built on a false dichotomy. It assumes that in order to accept science you must reject Christianity. However, the two are not in conflict. Science is a process (systematic study through experimentation), while Christianity is a philosophical claim (that a creator made the universe and provided salvation through Jesus).
Belief in Christianity is not only consistent with studying the natural world through experiments, it strengthens our motivation to do so. That's why modern science was founded primarily by Christians. Newton, Kepler, Bacon, Pasture, and many others believed that understanding the natural world was a way to understand the creator on a deeper level. This lead to many great discoveries and areas of study such as Astronomy, Chemistry, vaccination, and the scientific method itself.
Isaac Newton
Newton was a key figure in the scientific revolution and widely recognized as one of the most influential scientists of all time. He was a student of the Bible and wrote several theological works. He firmly believed God was necessary for the existence of material things.
"Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find suited to different times and places could arise from nothing but the ideas and will of a Being, necessarily existing."
-Isaac Newton
"This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being....This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is won't to be called Lord God "pantokrator," or Universal Ruler..."
-Isaac Newton
Fancis Bacon
Bacon established the scientific method of inquiry based on experimentation and inductive reasoning. He was a devout Christian who believed that nature pointed to a creator and atheism was the result of shallow philosophy.
"May God never allow us to publish a dream of our imagination as a model of the world, but rather graciously grant us the power to describe the true appearance and revelation of the prints and traces of the Creator in his creatures."
-Francis Bacon, The Great Instauration, 1620
"It is true, that a little philosophy inclineth man’s mind to atheism; but depth in philosophy bringeth men’s minds about to religion."-Francis Bacon
Johannes Kepler
Kepler was an astronomer who discovered three major laws of planetary motion, provided a new and correct account of how vision occurs, developed an explanation for the behavior of light in the newly invented telescope and discovered several new, semi regular polyhedrons. (1) He was a devout Christian who saw science and mathematics as a way to discover harmony in the universe God created.
“The chief aim of all investigations of the external world should be to discover the rational order and harmony which has been imposed on it by God and which He revealed to us in the language of mathematics.”
—Johannes Kepler
