In the Roman Catholic church, a day commemorating all the Christians believed to be in purgatory.

Celebrated on November 2, it was first established by Odilo (d. 1049), abbot of Cluny, in the 11th century, and it was widely celebrated by the 13th century. The date follows All Saints' Day, with the idea that remembering the saints in heaven should be followed by remembering the souls awaiting release from purgatory. Roman Catholic doctrine holds that the prayers of the faithful on earth will help cleanse these souls in order to prepare them for heaven.

▪ Christianity

      in the Roman Catholic church (Roman Catholicism), a day for commemoration of all the faithful departed, those baptized Christians who are believed to be in purgatory because they have died with the guilt of lesser sins on their souls. It is celebrated on November 2. Roman Catholic doctrine holds that the prayers of the faithful on earth will help cleanse these souls in order to fit them for the vision of God in heaven.

      From antiquity certain days were devoted to intercession for particular groups of the dead. The institution of a day for a general intercession on November 2 is due to Odilo, abbot of Cluny (d. 1048). The date, which became practically universal before the end of the 13th century, was chosen to follow All Saints' Day. Having celebrated the feast of all the members of the church who are believed to be in heaven, the church on earth turns, on the next day, to commemorate those souls believed to be suffering in purgatory.

      Priests celebrate mass wearing vestments of varying colour—black (for mourning), violet (symbolizing penance), or white (symbolizing the hope of resurrection).
