Dr. May provides a coherent introduction into the ethical issues surrounding sexuality as taught by the Catholic Church - both from the standpoint of Natural Law and John Paul II's personalistic philosophy. Faithful to the teaching of the Magisterium, May critiques revisionist views such as "consequentialism" and "proportionlism" that have curiously only arisen since Pope Paul VI's issuing of Humanae Vitae. May supplements his argument with copius citations of Church documents. Highly recommended for a Cathechist or anyone interested in what the Church truly teaches on sexual issues, May has a knack for relating difficult philosophical issues to the layperson without prior training.
