Optimism and pessimism are mere matters of optics, of how you look at things, and that can change from day to day, or with a new prescription for your glasses - or with a new set of ideological filters.

The impact remains to be seen; I don't think we can measure the enduring impact of John Paul II, for example, for another hundred, perhaps two hundred, years.

The pope [Francis] takes his vocabulary from his pastoral experience, not from the rhetorical tool kit of liberation theology, with its Marxist yammering about "center" and "periphery." The "peripheries," for Francis, are all those who have fallen through the cracks of late-modernity and post-modernity - in his native Argentina, because of colossal corruption, political and financial.

[Pope Francis] comes to that conviction [of family crisis] as a pastor, not as Brad Wilcox or Charles Murray. So he wants to challenge the Church to find pastoral responses to that crisis that meet real human needs.

In the Vatican, if you don't get something new done quickly you may not get it done at all.

Perhaps the dumbest of these story lines is that [Pope] Francis has re-opened conversation and debate in a Church that had been closed and claustrophobic for 35 years under John Paul II and Benedict XVI. I defy anyone who, over the last 35 years, has spent time on the campuses of Notre Dame or Georgetown, or who has read the National Catholic Reporter, or who has gone to a meeting of the Leadership Conference of Women Religious, to make that claim without experiencing a twinge of conscience that says, "I should wash my mouth out with soap."

[Pope Francis] is 78 years old and knows that his will be a short pontificate.
