All Hail, Adored Trinity Author unknown 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 songs that angels sing Unite the hymns of praise we bring.
