Theistic evolution is the concept that Darwin's theory of unguided evolution is absolutely true and unquestionable, but that this unguided process was secretly guided by God. (Any evidence of guidance is not for human eyes, however, especially scientists'.) To make this eyebrow raising assertion, theistic evolutionists Ken Miller and Francis Collins want us to believe a version of process theology, where God didn't know how intelligent beings would come out when he set the self-propelling evolutionary process into motion. We could as well have become not human beings, but big brained dinosaurs or intelligent mollusks, as Ken Miller has said. On his religion blog at Beliefnet ("Kingdom of Priests"), David Klinghoffer enjoys a sporting day at sea with the concept.
Theistic evolution makes no sense and simply begs for such satire. As science it defies Darwin's theory, as such Darwinians as Jerry Coyne and Richard Dawkins state. (If theistic evolution is unguided, even behind the scenes, it's not Darwinian evolution.) But theistic evolution also makes a hash of orthodox religious belief.
If the human body is just a fleshy vessel, and not the temple designed for the soul, then the downgraded product is justly relegated to the status of other animals. That's how we get Stephen Pinker and his views on radical animal rights. That is how we get to embryonic stem research, unlimited abortion and euthanasia.
There are reasons why orthodox Christians and Jews have granted dignity to the body; and why, for example, the traditional Judeo-Christian culture opposes self-mutilation. In contrast, the early Christian heresy of gnosticism sought to downgrade the body and set the spirit against it. But Christians especially treat the human body as different from all others and a partner of the soul. For example, Catholics, Eastern Orthodox, Lutherans and Anglicans are chief among the Christian denominations, though not the only ones, that attach great significance to the body of Christ in the Eucharist. Christ's body was raised from the dead, as, in Christian cosmology, our human bodies, too, will be raised at the day of Judgement.
It is doubtful that Collins or Miller have much appreciation of the thin theological ice on which they blithely skate. "The theology of the body", Pope John Paul II's phrase, is crucial to the faith, and the "body" that it, the Bible and tradition have in mind is irrefragably human and two legged, not aquatic.
Intelligent design is not involved in this fight since it doesn't identify a designer or get into theological issues. ID does have implications for theology (and philosophy), , of course, as does Darwin's theory. But it doesn't try to make them part of its scientific argument as the theistic evolutionists seemingly cannot resist doing.
