"Let us beset the just one, because he is obnoxious to us." How many of us will mutter such words to ourselves before Pope Francis' visit to the United States is over? Sure, we will lap up the mercy stuff. But what about when he challenges the "jealousy and selfish ambition" that permeates our hearts and souls? Left, right, center, whatever; none of us are getting a free pass. So how will you respond? Turf protection mode, as the wicked ones do? Or a hearty alleluia for grace that is truly sustaining?
