Washington D.C., Mar 1, 2018 / 01:10 pm (CNA).- The first stirring sentences of the new CDF letter to bishops, Placuit Deo, reject the very notion of a “new paradigm” by which “the newness of the Holy Spirit” could somehow mean a departure from the fullness of revelation which has already been revealed to us in Jesus Christ. Yet quickly the document turns to a different kind of “newness,” a newness which resembles the ancient errors of Gnosticism and Pelagianism, about which Pope Francis has frequently warned.
