The Congregation for the Doctrine for the Faith, previously Holy Office, after Vatican II saw an exponential increase in the production of normative or doctrinal texts aimed at explaining in an increasingly detailed way the stance of the Church's Magisterium on various aspects of faith and morality. Thus, the period between 1966 and 1978 sees the redaction of an array of documents of different literary genres by the Congregation for the Doctrine of the Faith, focusing on a variety of different themes: from the reception of Vatican II to infallibility, celibacy and sexuality. A survey of these documents and how the Congregation structures its activity after Vatican II can shed light on the workings of the formerly most powerful Congregation of the Roman Curia after Vatican II.
