A lecture given by Fr. Robert Barron (Rector, Mundelein Seminary/University of Saint Mary of the Lake; founder, Word on Fire) on May 8, 2014, at the University Cub of Chicago.
Cosponsored by Word on Fire
Fr. Robert Barron discusses how to put faith into action in today’s increasingly secular world. With Pope Francis as a model of how to present “the joy of the Gospel,” Barron argues that Catholics have a duty to awaken the faith of the baptized and bring back those who have drifted. While the message has remained unchanged since the first century, Catholics are called to share the beauty, goodness, and truth of the faith with new ardor, new expressions, and new methods that will reach the disenchanted and bring people closer to Christ and to his Church.
