This article argues for the dogmatic rather than just ethical significance of the biotechnological enhancement of human beings. It begins by reflecting on the close theological connections between salvation, sanctification, and affective and bodily transformation in light of the fact that affects and desires are in principle manipulable through biotechnological enhancement. It then examines the implications of this observation for questions of moral responsibility, asking whether biotechnological enhancement can be viewed as a kind of means of grace. The conclusion argues (...) that theological reflection on the relationship between affects, soteriology and bioenhancement reveals limitations of the emphasis on embodiment in recent Christian theology.
