A tiny fraction of the 1 billion baptized Catholics worldwide know who Archbishop Carlo Maria Viganò is. This despite the Italian prelate making global headlines in 2018, accusing Pope Francis of, among other alleged failings, abetting clergy sex abuse by lifting sanctions imposed by his predecessor Benedict 16th on an American cardinal who preyed on minors and seminarians.

Now, Viganò, in hiding since he criticized Francis, is back in the news. His June 9 essay argued that the Second Vatican Council of 1962 to 1965, also called Vatican 2, the Church’s most influential ecumenical council since the Council of Trent in the mid-1500s, had led Catholicism astray with this sweeping reforms in many aspects of Church life and doctrine.
