2018 marks the fiftieth anniversary of 1968 and Humanae Vitae as well as the centenary of the 1918 Armistice ending the Great War. The negative reception of Humanae Vitae is frequently viewed within the narrow causal lens of “the sixties” and in particular the tumultuous year 1968. However, the factors shaping the laity’s reception were 50 years in the making, including internalized authority and agency via the postwar currents of both “mysticism” and Catholic Action. Additionally, birth control was a discourse spanning 1918 to 1968.
