The specific focus of this conference is on the problems posed by the imminent recognition of homosexual marriages in one or more jurisdictions. The question posed by the "laws of nature" exception to the inter-jurisdictional marriage recognition principle is whether legally endorsed homosexual marriages, involving (as they must) societal approval and endorsement of homosexual conduct, are contrary to natural law. This paper will explore the classic natural law theory of Saint Thomas Aquinas and the reasons why that theory condemns homosexual conduct as being contrary to the law of nature.
