Video of a talk given by Professor de Mattei’s in May in Rome during the Rome Life Forum in which he discusses the sexual revolution that took place in the 1960s.  Professor de Mattei says that “Until the 1960s, all Church moralists taught this doctrine and all pastors and confessors referred to it as expressed in the encyclicals Arcanum of Leo XIII and Casti connubi of Pius XI, and in the teaching of Pius XII in numerous speeches given to married persons, doctors and to the Roman Rota.

But in the 1950s and 1960s, a process began by which traditional morality was subverted. The protagonists of the change were theologians like the German Jesuit Josef Fuchs (1912 – 2005), a professor at the Gregorian University, and above all the German Redemptorist, Bernard Häring (1912-1998), professor at the Alphonsian Academy. They applied to moral theory the theses of the nouvelle théologie which had only recently been condemned by Pius XII in his encyclical, Humani generis. This nouvelle théologie, a product of modernism, believed in the principle of the evolution of dogma. The new moralists extended this principle to the moral domain, denying the existence of an absolute and immutable natural law.”
