If the papal nuncio wants the USCCB to stand up and be counted, he may have to take the lead and challenge them to follow him -- that is, if he really wants change and isn't just repeating the (new) party line. 

Would he be willing, for example, to challenge the bishops to formally sponsor large numbers of families of undocumented parents in order to accompany them in the process of becoming fully incorporated into US society? Would he lead them in opposing attempts to deport families with children born here? Would he ask them to cease spending the people's funds on building/remodeling churches until they have effectively confronted the issues of the gospel as they emerge from our present situation? 

Or will he sit idly by as the bishops cozy up to the new administration with selective "faith-based initiatives?"
