All Souls Day
Historically, the Western tradition identifies the general custom of praying for the dead dating as far back as 2 Maccabees 12:42-46. The custom of setting apart a special day for intercession for certain of the faithful on November 2 was first established by St. Odilo of Cluny (d. 1048) at his abbey of Cluny in 998.From Cluny the custom spread to the other houses of the Cluniac order, which became the largest and most extensive network of monasteries in Europe. The celebration was soon adopted in several dioceses in France, and spread throughout the Western Church. It was accepted in Rome only in the fourteenth century. While 2 November remained the liturgical celebration, in time the entire month of November became associated in the Western Catholic tradition with prayer for the departed; lists of names of those to be remembered being placed in the proximity of the altar on which the sacrifice of the mass is offered.
