I saw a Youtube video from some group of biologists who were responding to the documentary Expelled: No Intelligence Allowed. These people were apparently Christians who were also biologists, and their point was that there is no incompatability between Christianity and evolutionary biology. The point was that God can use natural causes, and direct evolution, so they hold to evolution without being in conflict with their Christian beliefs. This view is relatively common, and is often called Theistic Evolution. It says that God used evolution, and guided it along the way.
However, it shows poor science and poor theology. First, as we are told by definition, evolution is caused by random mutations. The whole point is that it is purposeless and happens by chance. The whole idea is that all mutations happen by chance, and some mutations turn out to be beneficial, while most turn out to be deterimental. By defintion, natural selection works by random, purposeless series of chance accidents. By injecting an intelligent guide, they have re-defined evolution. They have also put a curious twist to the argument: If God works through mutations, why does He create a bunch of mutations that don’t work, so that He can get to a few that do? Taking the theistic evolutionary view reeks of compromise for the sake of convenience.
Second, theistic evolution is very poor theology. If a non-believer claims there is compatability between religion and evolution, then there’s no big deal, for non-believers aren’t supposed to know what they’re talking about in Christian theology. But when a Christian says this, it shows they haven’t thought through the implications of their belief system.
The book of Romans in the New Testament lays out a systematic description of Christian beliefs. In Romans 5, the Bible makes a comparison between Adam and Jesus. Adam is said to be a type for Jesus. In Adam sin entered the world, death through sin, plus judgement, condemnation, and separation from God. The reason Jesus died on the cross is to pay our debt to God and reconcile us to Him. So what does this have to do with evolution?
If evolution is true, even theistic evolution, then we gradually evolved from goo to homo sapiens and there was no first man, no Adam. If there was no Adam, then there was no first sin. Some theistic evolutionists might claim that God could have chosen one of the many slight variations of species that would have evolved along the way, then dubbed him Adam. Such a claim really doesn’t take into account the myriad upon myriad of gradual changes that would have had to have taken place to get from a one celled creature to modern human. Others are trying to say that Adam was a literary device, a figure of speech used to illustrate a point. These are both miserably poor viewpoints.
The whole point of Jesus coming to earth and dying on the cross was to reconcile us to God. If there was no Adam, are we to believe that there was no separation from God? No fall? The theistic evolutionist says that gradualism is true. They then have to say that the story of Adam was allegory or myth. They then have a dilemma. They have to either say Adam is not real, but the fall and separation from God are real, which is inconsistent, or they have to say that the fall and separation from God are allegory or myth also, which is heretical. So the theisitic evolutionist must either have an inconsistent belief system, with parts real and parts unreal, or they call themselves Christian but they are heretical, and have invented some other religion and called it Christian.
So anyone that tries to reconcile gradualism with Christianity is expressing bad evolution and worse theology.
