Veni Creator Spiritus

Veni Creator Spiritus ("Come Creator Spirit") is a hymn believed to have been written by Rabanus Maurus in the 9th century. When the original Latin text is used, it is normally sung in Gregorian Chant. As an invocation of the Holy Spirit, in the practice of the Roman Catholic Church it is sung during the liturgical celebration of the feast of Pentecost (at both Terce and Vespers). It is also sung at occasions such as the entrance of Cardinals to the Sistine Chapel, when electing a new pope, as well as at the consecration of bishops, the ordination of priests, when celebrating the sacrament of Confirmation, the dedication of churches, the celebration of synods or councils, the coronation of kings, the profession of members of religious institutes and other similar solemn events.
