The Church in the process of collapse, no longer able to actually physically enforce law outside its heartlands.

---

I will even answer the mighty earl
That asked of Wessex men
Why they be meek and monkish folk,
And bow to the White Lord's broken yoke;
What sign have we save blood and smoke?
Here is my answer then.

"That on you is fallen the shadow,
And not upon the Name;
That though we scatter and though we fly,
And you hang over us like the sky,
You are more tired of victory,
Than we are tired of shame.

"That though you hunt the Christian man
Like a hare on the hill-side,
The hare has still more heart to run
Than you have heart to ride.

-Chesterton, Ballad of the White Horse
