O God, the unwavering strength of all creation
Unmoved in yourself, forever the same,
Fixing the times by the light
Of day after day,
A fine ending to life’s sweet light,
And may there attend an eternal glory
To the prize of a death most holy.
And You who alone are his equal,
Who with the Spirit Paraclete
Reigns forever and ever, amen.
