Veni Sancte Spiritus
Veni Sancte Spiritus ("Come, Holy Spirit"), sometimes called the "Golden Sequence" (Latin: Sequentia Aurea), is a sequence sung in honour of God the Holy Spirit, prescribed in the Roman Rite for the Masses of Pentecost Sunday. It is usually attributed to either the 13th-century Pope Innocent III, or to the Archbishop of Canterbury, Stephen Langton, among others.
