Dr. Crawford’s teaching, research, and writing have spanned the areas of moral theology and philosophical ethics, the theological and philosophical anthropology of marriage and family, and legal and political philosophy. His publications have addressed human action, natural law, homosexuality, “gender identity,” and the anthropological implications of modern civil law.  He is currently engaged in research concerning morality and nature, as well as the theological and anthropological issues arising under modern legal theory, particularly as they concern marriage, family, and the person. Dr. Crawford has served as a theological advisor on the United States Conference of Catholic Bishops’ Subcommittee for the Promotion and Defense of Marriage and for Vatican Delegation Meetings at the Pontifical Council for the Promotion of Christian Unity. He is the author of Marriage and the Sequela Christi, published by the Lateran University Press, which discusses the relationship between marriage and the natural desire for God. He is in the final stages of completing another book, concerning the philosophical roots of civil law as they pertain to marriage, the family, and personhood. His articles have appeared in the Wall Street Journal, First Things, Communio, and Anthropotes, among other venues. His writings have been translated into several languages, and he has lectured on several continents.
