As a lifelong Catholic making the shift from young adulthood to whatever comes next , I see  Bishop Tobin's prescription to young adults leaving the church (more faith!) seems based on his own frustration and negative attitude towards that population, and towards those leaving the Catholic Church in general.   Jesus certainly expressed this frustration, as Bishop Tobin quotes from Luke 18.

However, in the very next verse in Luke, Jesus begins the parable of the Pharisee and the tax collector, which he addressed to "those who were convinced of their own righteousness and despised everyone else" (Luke 18:9).    As Jesus spoke of the need to acknowledge one's own sinfulness to receive justification and place in God's Kingdom, so must all of us as Catholics, both as individuals and as Church - Bishop Tobin included.   In castigating an "entitled generation" for their supposed lack of faith, Tobin places himself as the Pharisee rather than modeling how true humility can better serve God.
