Massachusetts bishops are addressing the state’s Catholics prior to the Feb. 21-24 Vatican Summit on the sexual abuse crisis. It is a crisis, they say, “that has again enveloped the life of the Church.” “The Summit Meeting, convoked by Pope Francis, will involve the presidents of over 180 Episcopal Conferences from throughout the world; along with (Boston) Cardinal (Sean) O’Malley, participating in his role as President of the Pontifical Commission for the Protection of Children. The goal of the Summit Meeting, as stated by the Holy Father, is ‘catechesis’ of the episcopal conferences,” the bishops said in a letter to the people of the Commonwealth, published below.
