Ambrose of Milan (340–397)

Come, Holy Ghost, with God the Son
And God the Father, ever One;
Shed forth Thy grace within our breast,
And dwell with us a ready Guest.

By every power, by heart and tongue,
By act and deed, Thy praise be sung;
Inflame with perfect love each sense,
That others’ souls may kindle thence.

O Father, that we ask be done,
Through Jesus Christ, Thine only Son,
Who, with the Holy Ghost and Thee,
Shall live and reign eternally.
