November is the month of the Dead, and November 1st, All Saints Day, is also the Day of the Dead. All Saints Day is one of only eight holy days of obligation. On this day we attend Mass and say prayers of thanksgiving for both the well and little-known saints; some of them, perhaps even from our own communities, who have inspired us and who, we believe, are interceding for us in Heaven.
Some Christians may be distressed by the fact that the Day of the Dead has many pre-Christian parallels, for example, Aztec festivals honoring the dead and worshipping the goddess of the underworld. This should not be reason for concern, as Catholics worship the Trinity, not other gods. And yet, of course there are many points of connection between Christianity and other religions. Christianity does not obliterate the unique cultural heritage of a people. On the contrary, the Church takes what is good and true in a culture and re-interprets it in light of the Christian story. This is known as inculturation. Learn how to make a Day of the Dead Altar in your home from NPR here: Decoding the Food and Drink on a Day of the Dead Altar
