Question: At our university campus ministry, we sing vespers every Friday. During the month of November, we sing vespers from the Office of the Dead for the souls of the friends, relatives, and benefactors of our community. Does the General Instruction of the Liturgy of the Hours (GILH), No. 245, permit one to celebrate the Office of the Dead even on an obligatory memorial, such as occurred in 2024 on November 22 (St. Cecilia)?
