One of the great challenges facing the Church in this generation is to foster in all the faithful a sense of personal responsibility for the Church’s mission, and to enable them to fulfill that responsibility as missionary disciples, as a leaven of the Gospel in our world. This will require creativity in adapting to changed situations, carrying forward the legacy of the past not primarily by maintaining our structures and institutions, which have served us well, but above all by being open to the possibilities which the Spirit opens up to us and communicating the joy of the Gospel, daily and in every season of our life. ~Pope Francis, Homily during Mass at Sts. Peter and Paul Cathedral, Philadelphia, Sept 26, 2015
