All Saints’ Day
On All Saints’ Day, the Church commemorates the communion of saints in a special way. The commemoration of All Saints’ Day stems from a belief that there is a powerful spiritual bond between those in heaven, and the living. All Saints’ Day celebrated the saints of the Church, both those that are well-known and those unknown. The day has been celebrated in some capacity since at least the 4th century. All Saints’ Day is a Holy Day of Obligation, meaning Catholics are required to attend Mass.
