Who the world rulest mightily,
Who art true God, in substance One,
And also God in Persons Three.

Now that we rise, stretch forth Thy hand,
And thus our soul in vigour raise,
That, burning with the love of God,
It may repay Thee thanks and praise.

To God the Father, glory be,
And also to His Only Son,
With the Great Spirit Paraclete,
While everlasting ages run. Amen.

– translated by Archbishop Edward Gilpin Bagshawe, C.O., Bishop of Nottingham, England
