One of the most divisive and important issues in the opening decades of this century has been the issue of marriage. The definition of marriage and law's relationship to it have been in the forefront of public debate, rising all the way to the Vatican and the US Supreme Court.

The International Union of Catholic Jurists offers in this book the work of renowned scholars, accomplished senior judges, and lawyers a significant contribution to the consideration of the "question of marriage" based on the classical tradition.

The contributors to the volume include Danilo Castellano (Italy), Ricardo Dip (Brazil), Bernard Dumont (France), Brian McCall (United States of America), Alejandro Ordóñez (Colombia), Luis María de Ruschi (Argentina), José María Sánchez (Spain), and Wolfgang Waldstein (Austria). The book was edited by the president of the International Union of Catholic Jurists, Miguel Ayuso (Spain).

Professor McCall's chapter presents the classical doctrine on natural law and its relationship to human positive law and then applies this analysis to the topic of marriage.
