There is an angel called ‘The Mercy’ in Masefield’s play, who says:
I bring the Mercy of God as peace, as balm,
As loving–kindness between soul and soul.
In the world’s storm I am the central calm,
In the world’s sky my brightness is the Pole. (p4)
God’s Mercy as the fixed, dependable Pole Star that helps us find the way; our loving-kindness to each other as the day-to-day expression of Mercy; here are two ideas worth holding onto. We need Mercy as a star to steer by: Mercy needs us to bring it to where it has to be.
As Masefield wrote elsewhere:
All I ask is a tall ship
And a Star to steer her by.
Polaris is the bright start to the left of this NASA image.
