In much of the world, November 1 is All Saints Day, or All Hallows.
For Roman Catholics, this is a “holy day of obligation” celebrating all those who are in heaven. (Eastern Christianity celebrates its own All Saints Day in the spring, after Pentecost.)
For Protestants, the word “saint” typically refers to any Christian, so the church universal (now and throughout time) is celebrated.
In addition, many cultures use this day to also celebrate the dead, especially those who passed away in the last year. This is done by special readings and ceremonies, family get-togethers, as well as visiting, cleaning, and leaving flowers at family graves. Nowhere is this so evident as in Mexico, where it’s also the first day of the Dia de los Muertos, or the Day of the Dead.
“Precious in the sight of the Lord
is the death of his saints.”Psalm 116:15
