Humanae Vitae and the Cross of Infertility (Video)
Elizabeth R. Kirk, JD
This presentation given at the 2018 fiftieth anniversary symposium of Humanae vitae, reflects on Sacred Scripture to arrive at a deeper understanding of the fruitfulness of the married couple.Kirk sees Church teaching on fruitfulness as representative of the teachings of Christianity on suffering, hope, and joy. She notes that the task of fruitfulness belongs to every Christian, and infertility is simply one example of the way in which human suffering can bear spiritual fruit.

Humanae Vitae and the Technological Conquest of Humanity (Video)
Michael Hanby, PhD
This presentation presented at the 2018 fiftieth anniversary symposium of Humanae vitae, argues along with St. John Paul II, that the “anthropological vision” of Humanae vitae is indispensable to defending the humanum against the anti-human tendencies of technological society.

In Defense of Humanae Vitae: Dietrich von Hildebrand on Human Generation as the “Superabundant End” of the Conjugal Act (Video)
Maria Fedoryka, PhD
This presentation given at the 2018 fiftieth anniversary symposium of Humanae vitae, argues that Dietrich von Hildebrand’s view provides the necessary metaphysical bridge that renders the order of nature morally relevant in the case of persons. Dr. Fedoryka sees this as providing a cogent argument against contraceptive use due to the law of love, according to which the two dimensions of union and fecundity must be respected in their absolute inseparability. 

Natural Family Planning and an Integral Vision of the Person 
Marshall Fightlin, MA, MTh, STL
This article discusses that love is the true meaning behind the marital act (which is an action spoken as words with our bodies). NFP can help couples to focus on the conjugal embrace as a mutual self-gift of love.

Perspective: Is NFP Good?
Rev. Richard M. Hogan, PhD and Rev. John M. LeVoir, MA (now Most Rev.)
