Biblical Limitations.
The subject of Biblical kinds has caused much division.
This argument is not just between naturalism and creationists, but even sets
believer against believer. In the Old Testament kinds are mentioned many times,
often when listing the clean and unclean animals. Kind appears to represent
roughly what taxonomy would classify as a genus — a grouping of similar species
— basically corresponding to the folk kind mentioned earlier. So far so good. The problem is old views maintain that these
kinds have been set by God with no drifting over the lines allowed, while
science claims that life evolved from single-celled organisms into the variety
of life we see today.
Much time and effort have been exerted by theologians and
scientists defending their respective positions. The arguments of one side
sound convincing until you hear the opposing view, and then that seems correct.
So which is right? It seems that we may never know for certain how God created
the world around us. There might be some limits to the variation of life on earth
which are impossible to exceed without the direct intervention of God. At the
same time we cannot close our eyes to the physical evidence.
