No one who reads and reveres the New Testament should doubt for a second that the pious poor and marginalized have something to teach all of us - including German theologian-bishops - about the truth of the Gospel and the mysteries of the Kingdom of God.

We're used to institutional-maintenance Catholicism, in which the institution ticks along by its own inertia and people are "born" into the Church. Francis knows that is over and done with: "Kept" Catholicism, whether "kept" by legal establishment or by cultural habit, has no future.

The dynamically orthodox orders of religious women will continue to grow, and the dying orders, which long ago opted for the lightest of Catholic Lite, will continue to die.
