In recent years there has been a growing body of literature in which theistic evolutionists advance arguments in support of their belief that evolution, properly understood, best describes God's work of creation. As they see it, there are mainly two obstacles in the way of an evolutionary account of morality: reductionism in science and a literal-historical reading of Genesis 1–3. The aim of this paper is to draw attention to some of their theological and philosophical arguments and the problems they create for both themselves and young-earth creationists. My starting points are the biblical picture of natural kinds, the image of God, and Jesus' understanding of Genesis 1–3. I then evaluate some of the weaknesses in the main arguments theistic evolutionists advance in support of their evolutionary account of morality. The conclusion is that theistic evolutionism is not only inconsistent with Scripture but also philosophically incoherent.
