Music like Holy Holy

"Holy, Holy, Holy! Lord God Almighty!" is a Christian hymn written by the Anglican bishop Reginald Heber (1783–1826).

It is sung to the tune "Nicaea", by John Bacchus Dykes. Written during the author's time as vicar in Hodnet, Shropshire, England, it was first published posthumously. Appearing in the influential Hymns Ancient and Modern, it is one of Heber's most popular compositions, enduring into the 21st century in many Christian traditions.

Intended for use on Trinity Sunday, the text invites worshipers to join in praising the trinitarian deity, paraphrasing Revelation 4:1–11.

The hymn was written in the early 1800s during Heber's time as vicar (1807–1823) in Hodnet, Shropshire, England, a period in which the author was prolific, writing more than 100 hymns, many having survived to modern times. It was first published posthumously in A Selection of Psalms and Hymns for the Parish Church of Banbury (Third Edition, 1826), and thereafter by the writer's widow in Hymns Written and Adapted to the Weekly Church Service of the Year (1827), one of the first hymnals to group their hymns by the liturgical occasion within the church year.
