All hail, adored Trinity!
All hail, eternal Unity!
O God the Father, God the Son,
And God the Spirit, ever One.
Behold to Thee, this festal day,
We meekly pour our thankful lay;
O let our work accepted be!
That sweetest work of praising Thee!
Three Persons praise we evermore!
One only God our hearts adore;
In Thy sure mercy ever kind
May we our true protection find.
O Trinity! O Unity!
Be present as we worship Thee;
And with the song that angels sing,
Unite the hymns of praise we bring. Amen.
J. B. Young, The Roman Hymnal (New York: Fr. Pustet & Co., 1884).
