I've long held that matters of an Old Earth or Young Earth are a matter of conscience. Let everyone be convinced unto himself (and keep it to himself).
However, the more I dig into things in the course of this Biologos dust-up, the more I am convinced that an Old Earth is incompatible with orthodox Christianity.
In that light, I will need to expand out formal arguments and definitions in a series of posts.
First, the Biologos "About Us" page says:
"We also believe that evolution, properly understood, best describes God’s work of creation."Now evolution means a lot of things, including:
- Deep time - geological periods and time spans; the geologic column, and fossil record
- Common descent - the belief that all living organisms descended from a single (very simple) organism or possible a common pool of self-replicating organic material
- Macroevolution - in the past referred to as "the transmutation of species", or what might be better termed "transmutation of kinds" (to oppose "reproduction within kinds")
- Stellar evolution - the belief that all matter started originally as hydrogen (one proton and one electron)
- Microevolution - this is the one thing everyone agrees on. This is "descent with modification" which has been readily observed.
