Pope Francis is planning a revolution to outlast him

In an article in Thursday's Guardian, columnist Andrew Brown wrote of Pope Francis: 'In his first year Francis has done all he can do. He must ensure his successor cannot undo all his progress.

"The temptation for observers is to look at the policies of the church and ask which of these he will change. But policy in the long run matters much less than culture; written rules matter less than unwritten ones."

A wise observation.
