Speaking to one of the most complex doctrines in the Christian faith, Holy Holy Holy was written by Reginald Heber to be used on Trinity Sunday. It quotes the Sanctus of the Latin Mass, which translated into English begins "Holy, Holy, Holy! Lord God of Hosts". The tune Nicaea was composed by Bacchus Dykes in 1861.
Holy Holy Holy - Lyrics
Holy, Holy, Holy, Lord God Almighty!
Unto everlasting days our song shall rise to Thee;
Holy, Holy, Holy, Merciful and Mighty!
God in Three Persons, blessed Trinity!
Holy, Holy, Holy! all the saints adore Thee;
Heaven’s elders cast their crowns down by the glassy sea;
Cherubim and seraphim worship too before Thee,
Who wert, and art, and evermore shalt be.
Holy, Holy, Holy! though the darkness hide Thee,
Though the eye of sinful man Thy glory may not see,
Only Thou art holy, there is none beside Thee
Perfect in power, in love, and purity.
