The "Francis effect": What did Bishop Lynch mean?

US media have been abuzz about a possible "Francis effect," as American bishops gathered for a conference in Baltimore this week.

The Washington Post, the first to address the "Francis effect" and prognosticate about what it might mean for the future of the American Church, cited as evidence the following comments from the blog of St. Petersburg, FL, Bishop Robert Lynch:

"The pendulum has begun to shift back and how long it will continue to do so, well that is up to the Holy spirit. For the moment, I find all this absolutely amazing."

"Shift"? From where? To where? "Amazing"? What?
