“In the question of the Church’s teaching on the regulation of birth we are called to profess in union with the whole Church the exigent but uplifting teaching recorded in the Encyclical Humanae vitae, which my Predecessor Paul VI put forth ‘by virtue of the mandate entrusted to us by Christ’ (AAS 60, 1968, p.485).

Ephesians 5:25-27
