When Archbishop Chaput suggests that people should leave the church, I believe he is demonstrating the weakness of his own faith and not theirs.  I would never suggest that this is a reason for him to leave the faith.  However, if he tires of ministering to sinners, I would suggest that is a good reason for him to not be a leader. We don't trust the people of God, guided by the Holy Spirit, to choose our leaders.  Instead, leaders are chosen for us, and then show their mistrust.  It is this consecration of unCatholic attitudes and outright fears that drives people away.
