Given the influence of Cluny, this custom first spread to other Benedictine communities associated with Cluny. Before long commemorating the faithful departed on this date was practiced in several dioceses in France before spreading throughout the Western Church. It was quite late coming to Rome, where it was accepted in the fourteenth century. In time, with All Saints day being established on 1 November in AD 835 and the celebration of All Souls on 2 November, the entire month of November came was dedicated to remembering the dead, at least in the Western Catholic Church.
There exists today in many Catholic parishes the practice of placing a list of names of those to be remembered close to the altar. This is a lovely custom we carry on at The Cathedral of the Madeleine, the parish in which I serve.
