This is the text as it appears in Hymns Ancient and Modern (1867):
Spirit of Mercy, Truth and Love,
O shed Thine Influence from above;
And still from age to age convey
The wonders of this sacred day.
In every clime, by every tongue,
Be God’s surpassing Glory sung;
Let all the listening earth be taught
The wonders by our Saviour wrought.
Unfailing Comfort, Heavenly Guide,
Still o’er Thy Holy Church preside;
Still let mankind Thy blessings prove;
Spirit of Mercy, Truth and Love.
O Holy Father, Holy Son,
And Holy Spirit, Three in One;
Thy Grace devoutly we implore,
Thy Name be praised for evermore. Amen.
Words: R.W. Kyle, 1842.
Tune: “Melcombe” Samuel Webbe, Sr., 1782.
