Still, responses of this sort—explicit, thorough, and precise—are necessary and helpful in other ways. They are helpful for the multitude of lay Catholics who remain confused and hurt by the pope's apparent madness, and feel timid or impious at the thought of making their concerns heard. They are helpful also for those who have steadfastly ignored all but the most benign words coming from Rome, since the most essential Franciscan errors are now very helpfully collected, summarized, and explained. Willfully ignorant Catholics are prodded to pull their heads out of the dirt and pay attention to reality. The signatories do not allow the Holy Father to get away with his careless words spoken in interviews, nor with his silence in response to the "implementations" of episcopal conferences.
That this correctio is being published during the quincentenary of Fr. Luther's revolution is not lost on its authors. There is a rather extensive section on "The Influence of Martin Luther" in the document (p. 12f), and it is worth nearly as much consideration as the marriage-related material.
Pray for the signatories. Pray for the pope. Only truth and repentance will heal these wounds. "For everyone who exalts himself shall be humbled, and he who humbles himself shall be exalted."
