I hope he's right, but it's funny how these things happen. After all, who was Martin Luther? One Augustinian monk in Germany. But when the time is right and various cogs in the wheel all turn in the right (or wrong) direction, massive change can grow out of small events. In fact, some make the argument that history is nothing but a serious of unforeseen ramifications of minor events.
As I see it, the reason is this is such a huge crisis is not just because of the crimes and sins of pedophilia themselves, but of the authority's reactions. What has already happened, and will only continue to happen if somthing's not done to remove the offending bishops soon, is that the teaching authority of the Church will be even more compromised than it is already. You can hear hints of it all over - what "right" do these people have to talk about abortion, name your issue here when they don't even have their own house in order?
