Bishop Caggiano is reaching out - trying to find ways to keep Catholics as practicing Catholics.  As to why people leave, young and old, think of the problem of living life in the modern world under rules formulated under the knowledge and conditions for a Medieval world.  It just doesn't work.

Bishop Vincent Long Van Nguyen of Parramutta Australia gave an astonishing homily at the re-dedication of a church rebuilt after a fire bombing.  He covers some important points - first of all acknowledging the impact of the sex abuse scandal on the Church and weaving in the gospel readings of the dedication day - the apocalyptic  words of Malachi of God's judgement day and Jesus warning of the crisis which His followers would face in the future, metaphorically describing the fall of the Temple in Jerusalem - which turned out to be prophetic rather than metaphorical.  you can find it here:  http://parracatholic.org/homily-for-33rd-sunday-in-ordinary-time-year-c/

But Bishop Long sees hope.
