The Encyclical Humanae Vitae: A Sign of Contradiction: An Essay in Birth Control and Catholic Conscience

Dietrich von Hildebrand’s The Encyclical Humanae Vitae: A Sign of Contradiction was published mere months after Pope Paul VI promulgated the eponymous encyclical. The much-anticipated encyclical quickly proved to be among the most contentious papal documents ever published; the uproar against it was immediate, intense, and widespread—even, perhaps especially, among Catholic intellectuals and clergy in Western countries.

It was in this milieu that Dietrich von Hildebrand published his The Encyclical Humanae Vitae: A Sign of Contradiction, and in doing so, became one of the first Catholic intellectuals of public stature to defend the encyclical.
