I think that most theistic evolutionists accept as scientific the claim that natural selection perfomred the creating, but would like to reject the acompanying metaphysical doctrine that the scientific understanding of evolution excludes design and purpose. The problem with this way of dividing things is that the metaphysical statement is no mere embellishment but the essential foundation for the scientific claim. I interpret this to mean that theistic evolutionists are implicitly accepting the metaphysical doctrines of atheists. As Stephen Meyer's essay in this volume points out, it is common for philosophers even at conservative Christian institutions to accept the rules of scientific naturalism, and to accept them for no better reason than that the secular world wills it to be so. This necessarily means endless ages of random changes which, in the process, leave untold waste and pain and death in their wake.
Theistic evolution is a contradiction in terms.
