History of Christianity


Many argue that Lumen Gentium, Vatican II’s Constitution on the Church, stands as the jewel in the Council’s crown. Pope John XXIII convened the 21st ecumenical council with the hope that the Catholic Church would engage in “aggiornamento” or updating. Central to his vision was the idea of updating the Church by “reading the signs of the times.”

To help celebrate the 50th anniversary of this critical document Bishop Madden reflects on Lumen Gentium’s significance at the council, the way that it creates important opportunities for dialogue, and Pope Francis’ use of key images from this text as he leads the Church into the future.
