If Francis was focused really on the interior lives of most Catholics....which is the MOST important by far thing he could do....he'd need far more courage...but he should open people up to a very difficult subject:  Reform of the lay.

How much and well and regularly are they praying?
Do they pray for the feelings they get from prayer, or do they pray for the love of God?
How much do they sacrifice daily, for the lives of millions around the world? 
How well do they fast? 
Are they fasting cheerfully, quietly, heroically, offering their little suffering for the good of many others, hopefully most for their family members, for their own cases of un-generosity?
How well do the lay prepare for Mass?  How much do they love the Mass?  How much love do they put into the Mass? 
How quietly and cheerfully do they put up with a bad homily?  Are they praying for their priest?

How well do the lay work? Are they offering their work to God, as part of the common priesthood?

Reform the lay.
