The bioethicists, whether libertarian, egalitarian or humanitarian, are by and large unconcerned with the positive good of keeping human procreation human, if upholding the difference between procreation and manufacture, between begetting and making. Few of them ponder what it will mean for the relation between the generations when children do not arise from the coupling of two but from the replication of one. Few seem to care about what it means for a society increasingly to regard a child not as a mysterious stranger given to be cherished as someone to take our place, but rather as a product of our will, to be perfected by design and to satisfy our wants.

What, then, does this suggest about eros and piety, about the love of women and the love of God? Love of the beautiful, this story seems to suggest, is at best a detour and a distraction, at worst a form of idolatry. Love of visible beauty is, at bottom, an attempt to make time stand still, to deny one’s own mortality and insufficiency, to attach one’s perishable self to some seemingly perfect and unchanging earthly form. Only if such love is transformed and domesticated by custom and marriage and turned toward its ever-present possibility, the generation of children, can it become, for the children of the book, a help to piety. For it is from the recognition of our own mortality and the resulting desire to give to our children not just life, but a good and righteous way of life, that men and women can open themselves to the ways and attitudes of the Bible. In the parental love of children lies the possibility of the sanctification of life – even in today’s world. Not eros as such, about which the text is at best neutral, but procreation is the biblical way by which the love of man and woman can lead to the love of God.
