Francis Bacon once wisely said, “God has, in fact, written two books, not just one. Of course, we are all familiar with the first book he wrote, namely Scripture. But He has written a second book called creation.” The Christian community is divided on the issue of evolution for a variety of reasons, but the primary reason for this division has to do with the perceived tension between the Bible and science (the study of nature). A secondary factor of this division has to do with the definition of evolution itself.
In order to determine whether or not Christians believe in evolution, it is important to address these two issues. We will look at them in reverse order.
The Definitions of Evolution
Evolution has four primary meanings. The first of these meanings is simply a synonym to the word “change.” This is not what we are talking about when we ask whether or not Christians believe in evolution.
The second and third definitions are related. One of them refers to naturalistic evolution as a worldview or philosophy in life. This naturalistic evolutionary worldview advocates for evolution on the macro scale (macroevolution) as the theory of the origin of life.
Macroevolution is a theory that says that the entire universe has a purely material cause and came about by chance. This theory posits that the Big Bang was the starting point some 13.8 billion years ago. At that time, life began through the formation of a single-celled organism. That cell reproduced, and over a period of billions of years, it produced offspring that underwent slow and progressive change that became gradually more complex until arriving to today.
Microevolution refers to the small changes within a species over a short period of time that occurs largely in response to environment. It is separated from the naturalistic evolutionary worldview, and it does not believe in the transformation of one organism into another organism. Under this theory, a human has always been a human and a bacterium has always been a bacterium. There is no such thing as species hopping under microevolution.
