Veni, Creator Spiritus

Veni Creator Spiritus (“Come creator Spirit”) is a hymn normally sung in Gregorian Chant. It is believed to have been written by Rabanus Maurus in the 9th century. Listen here.

According to newadvent.org, it is the only Breviary hymn retained by the Protestant Episcopal Church, a translation being given in the Prayer Book (Ordering of Priests). There are about sixty English versions.

COME, Holy Spirit, Creator blest,
and in our souls take up Thy rest;
come with Thy grace and heavenly aid
to fill the hearts which Thou hast made.
O comforter, to Thee we cry,
O heavenly gift of God Most High,
O fount of life and fire of love,
and sweet anointing from above.
Thou in Thy sevenfold gifts are known;
Thou, finger of God’s hand we own;
Thou, promise of the Father, Thou
Who dost the tongue with power imbue.
Kindle our sense from above,
and make our hearts o’erflow with love;
with patience firm and virtue high
the weakness of our flesh supply.
Far from us drive the foe we dread,
and grant us Thy peace instead;
so shall we not, with Thee for guide,
turn from the path of life aside.
Oh, may Thy grace on us bestow
the Father and the Son to know;
and Thee, through endless times confessed,
of both the eternal Spirit blest.
Now to the Father and the Son,
Who rose from death, be glory given,
with Thou, O Holy Comforter,
henceforth by all in earth and heaven.

Amen.
