The occasion of the fiftieth anniversary of Humanae vitae offers a teaching moment. In this compendium, experts representing a variety of disciplines including history, culture, theology, medicine, law, and psychology present their reflections upon God’s divine plan as described in Humanae vitae. The authors first presented this work in an abbreviated form at a symposium held at The Catholic University of America (April 4-6, 2018). Here, their presentations are substantively developed and hopefully will encourage further scholarly work. Ultimately, their purpose is to help the reader arrive at a more positive understanding of the teachings found in Humanae vitae. Although designed for the educated reader, the essays presume that when the teachings of Humanae vitae are embraced by men and women, they can contribute to the healing of the wounds of a world broken by sin but redeemed by Christ.
