This chapter discusses Revelation’s soundscape and meaning as a huge hymn festival around the marriage feast of the Lamb. It is about God’s goodness, mercy, and power over evil in a cosmic view, not a secret code for our calendars. Relationships between the book of Revelation and the church’s liturgy and music are explained, along with influences from the liturgy to Revelation and from Revelation to the liturgy. The Sanctus and Agnus Dei of the Ordinary, hymns, and other music for the worship of the church are included. Oratorios and Olivier Messiaen’s Quartet for the End of Time move to music, which, though outside the liturgy, also relate to Revelation and express its themes. Some implications about Revelation’s relevance for worship, music, and life together conclude the article. In Messiaen’s words, “It is all love.”
