What Is the Spiritual Meaning of St. Patrick’s Day?

St. Patrick’s Day is a celebration of Irish heritage marked with all things greenincluding Chicago famously dyeing the Chicago River the vibrant hue to celebrateas well as parades and festive music. But the origins of the often-rambunctious holiday are actually more stoic in nature. For hundreds of yearsSt. Patrick’s Day in Ireland was a religious observation with more modest fanfare and the closure of pubs. Some people still honor the holiday’s spiritual meaning today.

OriginallySt. Patrick’s Day was a spiritualreligious observance for Christians. For centuries in Irelandit remained primarily spiritualsays Diarmuid Wheelerheadmaster of Chelsea Academya Catholic elementary and high school in Front RoyalVirginia. Until the clause was repealed in 1960pubs in Ireland were legally prohibited from opening to respect the religious nature of St. Patrick’s Daythough drinking in public is now common on the holiday on the Emerald Isle and in the United States. Despite the holiday’s evolutionSt. Patrick’s Day continues to be a spiritual occasion for some people today.

St. Patrick’s Day originated as the saint’s dayor Christian feast dayfor the fifth-century bishop St. Patrick. It marks the anniversary of St. Patrick’s death on March 17 and entry into heavensays Sarah Waidlera visiting assistant professor of Irish languageliterature and culture at New York University.

St. Patrick’s feast day began in Ireland in the early Middle Agesbut as Waidler explainsit was likely celebrated internationally before too long. St. Patrick’s Day was formalized on the Catholic liturgical calendar in the 17th century. Originally“it was a solemn religious occasion with Massprayer and feastinghonoring Patrick’s missionary zeal and the arrival of Christianity in Ireland,” Wheeler says. People even traveled to churches dedicated to St. Patrick in hopes of receiving miracles or cures. After the Reformationboth Catholics and Protestants saw Patrick as an important saintdespite the fact that he wasn’t canonized.

Although St. Patrick’s Day is no longer a holy day of obligation for CatholicsIrish Catholics typically attend Masssays Christopher Maginna history professor at Fordham University and the past director of its Institute of Irish Studies. And while St. Patrick’s Day falls during Lentwhen many Catholics fastdiocesan bishops often permit the faithful to imbibe for the day.

There are many prayers and blessings associated with St. Patrick’s Day. St. Patrick’s Breastplate is a popular incantation or hymn that the saint allegedly wrote. Also called St. Patrick’s prayer or The Lorica—Latin for “body armor” or “breastplate”—it is a prayer of protection. Traditional blessings like “May the road rise to meet you” are also commonly recited.

St. Patrick’s Day shifted into a more secularIrish cultural celebration due to an influx of Irish immigrants in America in the 18th and 19th centuries. “In the 19th centuryamid a lot of discrimination[including] anti-Catholic bigotry and a desire to affirm their heritageIrish communities turned the day into big public paradesparties and cultural pride,” Wheeler says.

Boston held one of the first St. Patrick’s Day parades in either 1724 or 1737and New York’s parade came later in 1762Maginn says. The holiday was soon marked by annual paradeswhich were also held in Dublin starting in the 18th centuryand ornate society dinners in cities like New York and BostonWaidler says. In the early 20th centuryfestivities began to include play productions and games.

“Over timethat lively spirit influenced celebrations back in Irelandevolving [St. Patrick’s Day] into a global festival of Irish culture—musicdanceeverything green—while still rooted in faith for many,” Wheeler says.
