The Secretariat for Divine Worship at the United States Conference of Catholic Bishops has provided Liturgical Resources for the Papal Transition, a document which includes suggested texts for votive Masses for the current pope, during the time of the election of his successor, and upon the election of the new pope. It’s a useful resource. I have already begun to use material from it for use in my parish.
At the end of the document, it provides musical suggestions. While it is complicated to have a musical inventory that will suit the needs of all congregations, this list is deficient in a number of areas. There’s not a single suggestion of Gregorian chant provided. (For example, providing the Latin propers of each Votive Mass would be an ideal point of departure!)
Nonetheless, this is a valuable resource for all involved in planning and executing liturgies in the weeks ahead.
