The question of what, if anything, Christian theology as theology might contribute to ethical debates about appropriate uses of medical genetics has often been ignored. The answer is complex, and the author argues it is best characterized by an explanation of the analogous aspirations of the two: both have as their goal the perfection of the human being, both assert that the present disposition of the human body is on a fundamental level more often than not other than it ought (...) to be, and both aspire to transform the present state of the body toward a future state in which present imperfections no longer exist. Given these analogous concerns, it would seem that one of the primary moral contributions that Christianity can make to debates about medical genetics is to ask whether and to what extent the Christian vision of embodied human perfection is compatible with the vision of perfection offered by the sciences pertaining to medical genetics. The author pursues a discussion of this analogy and its implications in this essay. (shrink)
