who wrote the song holy holy holy lord god almighty
Holy, Holy, Holy "Holy, Holy, Holy!" is a Christian hymn written by Reginald Heber (1783–1826).[1][2][3] Its lyrics speak specifically of the Holy Trinity,[2][3] having been written for use on Trinity Sunday.[3] It quotes the Sanctus of the Latin Mass, which translated into English begins "Holy, Holy, Holy! Lord God of Hosts". The text also paraphrases Isaiah 6:3 and Revelation 4:1–11. John Bacchus Dykes composed the tune Nicaea for this hymn in 1861.[1][2][3] The tune name is a tribute to the First Council of Nicaea which formalized the doctrine of the Trinity in 325.[2][3]
