This article responds to an article by Francis J. Beckwith that argued that the consistent application of generic liberal principles requires that same-sex marriage not be recognised in civil law. This response demonstrates that Beckwith's article contains a series of interpretative and substantive flaws that render his argument unsuccessful. These relate to a misinterpretation of core liberal principles and a sidestepping of the matter of undue bias against same-sex partners. In correcting these flaws I tentatively propose a Voltairean argument in (...) favour of same-sex civil marriage for those citizens with moral qualms about same-sex relationships derived from their reasonable comprehensive doctrine.

The “new natural lawyers” (NNLs) are a prolific group of philosophers, theologians, and political theorists that includes John Finnis, Robert George, Patrick Lee, Gerard Bradley, and Germain Grisez, among others. These thinkers have devoted themselves to developing and defending a traditional sexual ethic according to which homosexual sexual acts are immoral per se and marriage ought to remain an exclusively heterosexual institution. The sterility objection holds that the NNLs are guilty of making an arbitrary and irrational distinction between same-sex couples (...) and sterile heterosexual couples. The NNLs believe that it is a necessary condition for two people’s being morally and legally entitled to get married that they be able to perform sexual acts that are “suited to procreating.” But sterile heterosexual couples are incapable of performing such acts. Therefore, it should follow from the NNLs’ own premises that sterile heterosexual couples are not entitled to marry. But the NNLs do not draw this conclusion. Instead, they maintain that sterile heterosexuals can marry while denying that the same is true of same-sex couples. The sterility objection claims the NNLs are being inconsistent in treating the two kinds of couples differently. Although the sterility objection has been endorsed by recent critics, I don’t think it has yet been adequately defended. The NNLs have responded by arguing that there is a sense in which the sex acts of sterile heterosexual couples are as suited to reproduction as those of fertile heterosexuals. Thus they maintain that the distinction they draw between the two kinds of couple has a rational basis. A successful defense of the sterility objection must show that this response on the part of the NNLs fails. Such is the task I undertake in this paper. I argue that the NNLs’ response fails because acts of penile-vaginal intercourse between sterile heterosexuals lack the actual causal power to produce conception that sexual acts need to be considered truly reproductive, and because their assumption that penile-vaginal intercourse always functions reproductively is bad biology.

Abstract. For the past two decades, I have been developing an integrative Christian marriage theory, based in part on a grounding concept of natural law and an overarching theory of covenant. The natural law part of this theory starts with an account of the natural facts, conditions, interests, needs, and qualities of human life, interaction, and generation—what I call the “premoral” goods or realities of life. It then identifies the natural inclinations of humans to form enduring and exclusive monogamous marriages (...) and to preserve these units as the central site for intimacy, procreation, and nurture of children. In this paper, I first summarize this natural law theory of marriage and then compare it to the formulations of other modern Christian thinkers. I also defend this theory against various modern critics of natural law—in part by reinterpreting some traditional natural law teachings that in my view have been misunderstood, in part by looking at the interesting convergences between the insights into sex, marriage, and family life offered by contemporary Christian theological ethicists and by evolutionary biologists and biological anthropologists.
