All Souls Day – 02 Nov
Feast in commemoration of the faithful departed in Purgatory. Abbot Odilo of Cluny instituted it in the monasteries of his congregation in 998, other religious orders took up the observance, and it was adopted by various dioceses and gradually by the whole Church. The Office of the Dead must be recited by the clergy on this day, and Pope Benedict XV granted to all priests the privilege of saying three Masses of requiem
- one for the souls in Purgatory
- one for the intention of the Holy Father
- one for the priest‘s
If the feast should fall on Sunday it is kept on 3 November.
